PROTEUS XR/a

The Proteus XR/a Table is equipped with an emergency stop switches located on the left and right side of the table. (See Illustration 6-1)

In the event of an emergency, press the emergency stop in with force. When normal conditions are confirmed, turn the button clockwise so the table can be powered up.

GE MEDICAL SYSTEMS Operator Manual REV 22 DIRECTION 2259724-100

- Foot Pedals. The control pedals are used to raise and lower the table top and to

free the table top for longitudinal and transverse positioning.

- Bucky Assembly. The Bucky assembly is mounted on a carriage beneath the table top. It

contains a Manual Cassette Tray which accepts all standard sizes of cassette ranging from130 x 180 mm to 350 x 430 mm (5 x 7”to 14 x 17”).

An ionization chamber can be located beneath the Bucky grid to implement automatic exposure control. This is a optional component.

- Telescopic Covers. These covers are assembled in two levels. Their purpose is to cover

the table power supply, and the electronic and mechanical components located in the table base. This is essential when the table top is raised or lowered.

- Hand Grips. Two hand grips are included with the Proteus XR/a. These serve to

maintain the patients’ hands away from the table top edges and to give patients a feeling of security. The grips are not intended to support the weight of patients. For safety reasons the patient handgrips must be used during all examinations. The grips slide onto the side rails of the table top. They can be locked in place in any position along the side rails with the thumbscrews.

- Table Inhibition Buttons. Two Table Inhibition buttons are located on both front and back table

base. They are used to inhibit the table up-down and table top movement.

If the cassette tray is not inserted all the way into the Table Bucky, the exposure will be prohibited either with or without AEC.

To remove a cassette from the manual cassette tray, pull the tray out fully by its handle. Pull up on the tightening lever and pull it back away from the cassette. The cassette is now free to be removed.

It is important that the X-ray tube unit be transversely centered accurately with the center of the Bucky. Density cut off at the edges of the film and appearances of grid patterns indicate inaccurate transverse alignment. With an anti-diffusion grid vertical alignment is not critical, and tilted tube techniques may be used without undue cut-off.

The center of the cassette tray handle is marked to indicate the longitudinal center of the Bucky to the X-ray beam. Depending on the position of the tabletop, the Bucky handle may need to be pulled out to allow the collimator light to shine on it.

CHAPTER 7 PROTEUS XR/A OVERHEAD TUBE SUSPENSION

7-1 Introduction

The Overhead Tube Suspension (OTS) is the positioning device that supports the X-ray tube and OTS Console.

Each suspension provides convenient movement and accurate positioning of the equipment.

The X-ray Tube Overhead Suspension consists of four major elements

-The Overhead Rail System,

-The Telescopic Column and Carriage,

-Tube Support and User Interface.

-Multileaf Collimator \ Eclipse Proteus Collimator .

ILLUSTRATION 7-1

OTS Components

7-2 Overhead Rail System

The overhead rail system consists of the stationary rails (ceiling or wall mounted) and a bridge that travels longitudinally (LONG) along the rails. Guide bearings maintain alignment of the bridge with the rails and the X-ray table.

An electric lock controls motion of the bridge along the rails. A switch marked

“LONG” on the user interface activates this longitudinal lock. Press down the

switch will releases the lock. Releasing the switch reapplies the lock.

7-3 Telescopic Column and Carriage

The carriage rides laterally (LAT) within the bridge. The lateral lock controls its motion. The switch marked LAT on the front of the collimator operates the lock. This switch functions in the same manner as the one for the longitudinal lock.

The telescopic column permits vertical (VERT) travel of the tube unit. The vertical lock controls its motion. The switch marked VERT on the user interface operates the lock. The switch must be held down while moving the tube unit.

The vertical load is balanced by a spring counterpoise system within the carriage. The counterpoise system is equipped with a safety-locking feature to prevent the tube unit from falling in the event of spring or main cable failure. Adding an accessory such as a collimator extension cylinder may cause the suspension to be slightly out of balance.

Proteus XR/a Collimator accessory weight may not exceed 4.5 kg (10 pounds), and Eclipse Proteus Collimator accessory weight may not exceed 7.0 kg (15.4 pounds).Use special care when using such an accessory since the tube unit will tend to descend when the vertical lock is released.

SID SENSOR AND BRACKET LOCATIONS

Use of Longitudinal and Transverse Detents

The suspension is equipped with Longitudinal and Lateral detents to automatically apply the locks and signal the collimator when the tube is positioned at specific

SID’s, for vertical table or wall stand procedures. The locks are actuated through

SID detent sensors that ride along the bridge and stationary rails, and detect coded brackets set at pre-determined locations. For table, lateral detent is set at the table lateral centerline. For wall stand, lateral detent is set at the wall stand panel lateral centerline, and the longitudinal detent is set at SID 180cm(72 inches) and 100cm(40 inches). Selection is made at the time of installation and is usually with the focal spot over the longitudinal table and wall stand centreline. The locks are actuated through electrical detents and the switch marked

DETENT. Depress the “DETENT” switch and the “LAT” switch to index the focal

spot over the longitudinal table centerline. Depress and momentarily hold the

“LONG” switch (with the “DETENT” switch still depressed) to index the focal spot

at one of the pre-selected SID’s. When reaching the approximate position, motion should be slow to avoid passing over the detent bracket. To move out of the indexed positions, depress the “DETENT” switch a second time.

Use of Vertical Detent

Note: The longitudinal and lateral locks are the electromagnet type and are “off”

when the power is off. They are applied when the power is on and their switches are in the upper position (not depressed). To release the locks, depress the switches.

There is a vertical detent switch in the Overhead Tube Suspension column that will set the locks when the tube reach the pre-set distance, such as 100cm (40

inches) above the film. Depress the “DETENT” switch and the “VERT” switch to

index the focal spot at the 100cm (40 inches) SID.

Note: This function doesn’t apply to tube angulation radiography.

7-4-3 X-ray Tube Angulation

ILLUSTRATION 7-6

X-RAY TUBE ANGULATION

The other rotational feature of the tube support permits TUBE ANGULATION about the short axis (front to back). The amount of angulation is indicated on the user interface. Limits of angulation are 180° in either direction from the X-ray beam down position. The angulation lock that is controlled by the switch marked ANG maintains angular positions. while angulating the tube.

Angular positions will detent every 90° automatically starting with the X-ray beam down position. To move out of a detent position, depress the ANG button and hold this switch down, rotating the tube assembly. Release the button to lock the tube in place.

Note: Angulation lock is the Electro Magnetic, spring applied, type. They remain

“on” when the system power is off. They can be released only when the power is on and their respective switches are depressed. In emergencies, the tube unit can be moved against the force of the locks.

The gravity center of the angulating parts (including tube, OTS console,

collimator, etc.) is lower than the angulating axis. So when tube angulation is 90 degree, if release the angulation lock, there will be a trend of tube to

angulate downward. When tube angulation is 90 degree, please pay attention to hold the OTS console with both arms as release the angulation lock.

Note: When taking exposure with the Wall Stand (GPCP No. 600-0301) or SG120

Wall Stand (GPCP No. 2402562), if the Wall Stand or SG120 Wall Stand is

mounted to the side of the Table (C or D in the illustration below), the X-ray

tube should only be angulated anticlockwise and not be angulated

clockwise. When angulated anticlockwise, the position of the X-ray tube Anode is lower than angulated clockwise, so the heat dissipation performance of the tube is distinctively better than angulated clockwise.

8-2 Operation

8-2-1 Vertical Positioning

The Bucky/Stationary grid cabinet is held in vertical position by Electromechanical locks.

By operating the vertical lock handle (located on both left and right side of the Bucky carriage) the Electro-mechanical locks can be released and the carriage can be moved up and down, for infinite vertical positioning within its travel range.

Note: The Electro-mechanical lock of wall stand is a Power Off Protection Lock.

The lock is negative without power on.

8-2-2 Cassette Loading

This wall stand is equipped with cassette tray which is inserted into the Bucky tray

slot.

1. To insert a cassette, pull the tray out of the Bucky to the tray stop.

2. Insert the shelf (See Illustration 5-2) in the centering scale slots that correspond to the cassette size selected.

3. Lift the clamping lock handle to unlock it.

4. Slide the clamping apart to insert a cassette on the shelf. Clamp and center the cassette transversely on the tray.

5. Push the clamping lock against the cassette and lock it by pressing down the lock handle.

6. Push the cassette tray all the way into the Bucky.

Note: If select “Wall Stand” as the image receptor on System Console (refer to

section “5-3-1 Technique Selection” in Chapter 5) when taking exposure

either with or without AEC, the cassette tray must be inserted all the way into the Wall Stand Bucky. If the cassette tray is not inserted all the way into the Bucky, the exposure will be prohibited either with or without AEC.

Note: To prevent damage to the cassette clamps locking assembly always close it

prior to inserting (pushing) the cassette tray into the Bucky.

Note: Normally the cassette tray does not have to be completely removed from the

Bucky in order to load a cassette. Cassette may be inserted in the tray by pulling the tray until movement is stopped by the catch on the lower rear of the tray.

However, if it is desired to remove the tray from the Bucky, pull the tray out until it is stopped by the catch, then press the catch against the tray bottom and hold it while sliding the tray out.

IT’S A TWO-HAND OPERATION BUCKY. PLEASE BE CAREFUL WHEN YOU

POSITIONING OF ION CHAMBER DETECTORS

 Sensing area Number 2 is at the center of the x-ray beam.  Area Number 1 and Area Number 3 can be selected to cover an exposure of

two symmetrical parts of the body at a time, such as the lungs or the kidneys.

 If this is the case, care should be taken to center the patient and detector

areas accordingly.

PROTEUS XR/a

8-5

GE MEDICAL SYSTEMS Operator Manual REV 22 DIRECTION 2259724-100

8-2-5 Applications for Detector Areas

Applications for the detector areas are given in Table 5-1 For example, one application for the ion chamber detector is chest radiography.

 In this application area 1 and area 3 must be located in line with radiation

transmitted through the left and right lung fields, so that areas 1 and 3 are not influenced by variations in tissue opacity caused by the heart or vertebrae.

If the patient is improperly positioned and the sensing areas are exposed to direct radiation, the phototimed exposures will be too short and the films underexposed.

The opposite will be true if the patient’s thoracic spine or sternum is

positioned over the sensing areas.

 The basic positioning requirements are also important when using area 2.

Misalignment may result in unusable film. Therefore, care should be taken when positioning the area of interest over area 2.

1. Before positioning the patient, align the x-ray tube to the center of area 2.

2. Collimate the light field to an area of 205mm-230mm. This light field is now cen-tered on area 2 and encompasses two sides of areas 1 and 3. See Illustration 8-3.

3. Position the patient’s area of interest within the light field. Readjust the light field to the desired size. The detector sensing area is now aligned with the patient area of interest.

 When using area 2 only, a light field (51mm-102mm), if properly centered,

will define that area and can be used to align a particular body portion with it.

bucky in order to load a cassette. Cassettes may be inserted in the tray by pulling the tray until movement is

stopped by the catch on the lower rear of the tray.

from the bucky, just pull the tray out until it is stopped by the catch (located on the upper or lower side of the tray depending if the SG120 is left or right tray insertion configured), then press the catch to the bottom of the tray and keep it pressed while you slide carefully the tray out of the bucky assembly.

Procedure

1. Extract the cassette tray pulling by its handle.

2. Pull up the tightening lever and remove it from the cassette, which remains free.

3. Remove the cassette.

The SG120 may operate with an Ion Chamber Detector. The three field pattern on the front panel of the SG120 corresponds to the three detection areas for the Ion Chamber Detector.

9-4-5 Alignment

It is important that the X-ray tube is accurately centered with the Bucky transversely. If the alignment is not accurate, density cut-off at the edges of the film and appearance of grid patterns may be found.

The alignment is not critical when an anti-diffusion grid is used. In this case, tilted tube techniques may be used without undue cut-off.

Note: The cassette tray handle is marked to indicate the vertical center of the

bucky. To assure the bucky is vertically aligned with the X-ray beam, move the bucky or the tube in order the collimator light is aligned with this center mark.

9-4-6 Frontal Panel

The bucky assembly mechanism and grid can be easily accessed by removing the front panel of the SG120. Loosen the screws that hold the front panel to the bucky support and remove it with care.

9-4-7 Bucky Rotation

It is possible to rotate the SG120 bucky assembly SG120 from 0º to 180º. The rotation movement is permitted means of the lock lever located on the back side of the bucky assembly.

Procedure

1. Release the lock lever.

2. Rotate the bucky to position.

3. Put the lock lever back into locked position.

Note: The bucky can be rotated CW (clockwise) or CCW (counter-clockwise). Note: To avoid degradation of image quality and loss of bucky functionality, it is

recommended not to perform exposures with the bucky in other position than 0º or 180º.

9-4-8 Bucky Angulation

The bucky is designed to operate only at 0º or 180º positions, but will function in a range within 30º of these positions. The image quality may be degraded, however.

The SG120 bucky assembly can be angulated in a range that varies from –20º to 90º. The bucky in locked means of the electro-mechanical detents located in the bucky support assembly. The angulation movement is left free when activating one of the pushbuttons located behind the bucky support.

Procedure

1. Press one of pushbuttons located behind the bucky support.

2. Keeping the pushbutton pressed, angulate the bucky to the desired position.

GE MEDICAL SYSTEMS Operator Manual REV 22 DIRECTION 2259724-100

Note: For SG120 Wall Stand Auto Exposure Control (AEC), please check the form

below to ensure the fulfillment of each item of AEC requirements. Otherwise, the exposure operation will cannot be made under AEC.

For SG120 Wall Stand, there are two circumstances (Bucky is in vertical

position and Bucky is in horizontal position, refer to Illustration 9-2) under which the AEC exposure can be made. And in the form below, The AEC exposure requirements under these two circumstances are specified respectively. Pay attention to distinguish these two sets of requirements.

Note: For SG120 Wall Stand, to take exposure under AEC, the Cassette must be

loaded in the tray, and the Cassette tray must be inserted all the way into

the Bucky. And the image receptor must be selected to be “Wall Stand” on System Console (refer to section “5-3-1 Technique Selection” in Chapter 5).

For SG120 Wall Stand, if the cassette is placed on the top of the Bucky

(Bucky is in horizontal position, Angulation is 90°, see illustration 9-2) while not be loaded in the tray and inserted into the Bucky together with the tray, the exposure only can be taken without AEC. And the image receptor

should be selected to be “Table top” on System Console (refer to section

“5-3-1 Technique Selection” in Chapter 5).

For SG120 Wall Stand, if the tray is not inserted all the way into the Bucky,

the exposure will be prohibited either with or without AEC.

Note: For the vertical position, rotation and angulation of SG120 Bucky, please see

contents 9-4-1, 9-4-7 and 9-4-8 for references. For OTS Console position and Collimator override switch on OTS Console, please see 7-3, 7-4-3 and 75 in Chapter 7. For Image Receptor Mode chosen on System Console, refer to 5-3-1 in Chapter 5.
