WARNING

THE FOLLOWING WARNINGS, CAUTIONS AND NOTES MUST ALWAYS BE CONSIDERED WHILE SERVICING, IN ORDER TO AVOID EITHER PERSONAL INJURY OR DAMAGE TO THE UNIT.

CAUTION RADIATION SAFETY RULES

Some procedures described in this manual produces X-ray radiation. Always follow rules for radiation safety.

Never touch or scratch the surface of the x-ray tube radiation window. The window is made of beryllium that can be harmful if inhaled or swallowed.

Never attempt to open the TUBE-HEAD. It does not contain any serviceable parts and this would make it inoperable and void the warranty.

Never make any exposures without the Mo/Al filter in the beam, or without the beam limiting device (collimator) in place. Otherwise the radiation safety cannot be guaranteed.

CAUTION ELECTRICAL SAFETY RULES

The unit contains hazardous voltages. While servicing internal parts, always disconnect the unit from the mains (if possible) by removing the plug from the wall outlet, and wait for 2 minutes before touching any electrical parts.

Always replace the fuses with ones of the same type and rating. Otherwise patient, operator or equipment safety cannot be guaranteed.

The circuit boards can be damaged due to static discharges and requires careful handling and storage.

CAUTION GENERAL SAFETY RULES

The unit must be serviced only by qualified personnel, trained by PLANMED Repairs and parts replaced by unqualified personnel carry no warranty.

MANUAL VERSIONS

2 MANUAL VERSIONS

PLANMED pursues a policy of continuous product development. Although every effort is made to produce up-to-date product documentation this manual should not be regarded as an infallible guide to current production specifications. Planmed reserves the right to make changes to specifications without prior notice. This manual is valid for all versions of the Sophie Mammography X-ray units with SID 650mm. In case you have the unit with SID 600mm, you need a technical manual revision 9.

NOTE	THIS TECHNICAL MANUAL IS VALID FOR SOFTWARE REVISIONS: TUBE CPU 2.41
	(OR LATER) AND REAR CPU 4.41 (OR LATER).
	If you find that your SOPHIE doesn’t have some keyboard functions, or its keyboard
	functions differs from procedures described in this manual, then either the software
	must be replaced with at least the above mentioned revision, or you have to relate to
	an older version of this manual. The former procedure is recommended.

3 UNIT MODELS

All Sophie Mammography X-ray unit models are electrically and mechanically identical, except for some minor details. This manual is valid for all versions since the differences are small.

The darkroom versus daylight differs only in the size and dimensions of the cassette table and film marking device.

The mobile versus the stationary units differs only in the base wheel system and the X-ray tube locking system (for transportation).

Daylight units can be converted to darkroom units (and vice versa), please contact PLANMED for details.

SOFTWARE REVISIONS & COMPATIBILITY

4 SOFTWARE REVISIONS & COMPATIBILITY

Background

Since this unit is fully microprocessor controlled, its operation is controlled by the currently installed software. PLANMED reserves the right to improve functionality or to add new features to the product by modifying the software and/or hardware. Manuals are updated accordingly and technical bulletins published in order to inform about these changes or additions.

Hardware compatibility

As a general rule; new software releases are compatible with all existing hardware. New software releases (or possible upgrading kits containing new software) are normally directly compatible with existing hardware, but not necessarily without some re-calibration procedures.

Software numbering & compatibility

Since the unit contains two communicating microprocessors, these must be able to “understand” each other.

Incompatible software versions should never be used together, the unit would either be totally non-functional, produce continuous error codes, or some important features or functions could be missing. However, no damage or safety hazard would result if two non-compatible software chips are accidentally used together.

The following table contains information about compatible software versions. Use versions together only as listed in this table.

7.2Toshiba E7272 x-ray tube ratings

Manual exposures

With manual exposures the tube kV, mAs and focal spot can be selected by the user. The mA value is automatically determined by the selected kV value, and the exposure time is determined by the selected mAs value. The mA value used is always the highest possible value, that depends on the kV value, focal spot, exposure time and line frequency (see following table on the next page). The maximum exposure time is 6.0 sec. for the large focal spot, and 9.9 sec. for the small focal spot. The minimum mAs value is 10 mAs and it can be increased in approx. 20% steps to the maximum (see values below). The maximum mAs value for the large focal spot is either 300, 500, 550 or 600 mAs, depending on the value of the service mode parameter 6. The maximum mAs value for the small focal spot is 200 mAs.

The possible mAs values are: 10, 12, 14, 16, 18, 20, 25, 30, 35, 40, 50, 60, 70, 85, 100, 120, 140, 160, 180, 200, 225, 260, 300, 350, 400, 450, 500, 550, 600.

Automatic exposures

Automatic exposures are terminated when the radiation detector indicates that the required dose has been reached. In this mode the kV is selected by the operator and mA is chosen to be the maximum allowed mA for the selected kV and Hz (line frequency).

If the exposure time is longer than 1 sec (5 sec for the small focal spot) then a falling load technique is used. The exposure is started at the mA as specified in the following tables. The accumulated dose is checked at 0.45 sec (2.45 sec for the small focal spot) and if it has reached more than half of the required dose, the exposure can be continued at the same mA level, and will be terminated within 1 second (5 seconds for the small focal spot) - well before the tube is overloaded.

If the accumulated dose is detected to be less than half of the required, a longer exposure time than the one specified for the tube current can be expected. Therefore the tube current is reduced at this time (after 0.45 or 2.45 sec exposure) to a lower mA that, when added to the already produced tube loading, will not exceed the maximum tube rating. The falling load current levels are listed in the two following tables.

Thermal ratings

Two separate methods are used to protect the tube from overload. One is measuring the tube head enclosure temperature and if it exceeds 60 °C no further exposures are allowed until it falls below 60 °C.

The other method keeps the average input power into the tube below or equal to 500W. The exposure parameters are limited as indicated by the following tables, but this feature forces a waiting time between the exposures to ensure that the average power into the tube never can exceed this limit. For example if an exposure of 24 kV, 100 mA, 1 sec is performed a wait period of 5 seconds is calculated and no further exposures are allowed until this time has elapsed.

There is no way to bypass these safety feature under any circumstances, and it is thus virtually impossible to overload the X-ray tube.

USER’S STATEMENT FOR PLANMED SOPHIE (TOSHIBA

9.1Toshiba E7290 x-ray tube ratings

Manual exposures

With manual exposures the tube kV and mAs can be selected by the user. In order to keep the exposure times at minimum the required mAs is always achieved at highest possible tube current for the kV selected. The parameters are listed in the following table.

Automatic exposures

Automatic exposures are terminated when the radiation detector indicates that the required dose has been reached. In this mode the kV is selected by the operator and mA is chosen to be the maximum allowed mA for the selected kV.

If the exposure time is longer than 1 sec (5 sec for the small focal spot) then a falling load technique is used. The exposure is started at the mA as specified in the following table. The accumulated dose is checked at 0.45 sec (2.45 sec for the small focal spot) and if it has reached more than half of the required dose, the exposure can be continued at the same mA level, and will be terminated within 1 second (5 seconds for the small focal spot) - well before the tube is overloaded.

If the accumulated dose is detected to be less than half of the required, a longer exposure time than the one specified for the tube current can be expected. Therefore the tube current is reduced at this time (after 0.45 or 2.45 sec exposure) to a lower mA that, when added to the already produced tube loading, will not exceed the maximum tube rating. The falling load current levels are listed in the following table.

Thermal ratings

Two separate methods are used to protect the tube from overload. One is measuring the tube head enclosure temperature and if it exceeds 60 °C no further exposures are allowed until it falls below 60 °C.

The other method keeps the average input power into the tube below or equal to 500W. The exposure parameters are limited as indicated by the following table, but this feature forces a waiting time between the exposures to ensure that the average power into the tube never can exceed this limit. For example if an exposure of 24 kV, 100 mAs is performed a wait period of 5 seconds is calculated and no further exposures are allowed until this time has elapsed.

There is no way to bypass these safety feature under any circumstances, and it is thus virtually impossible to overload the X-ray tube.

B UNPACKING & INSTALLATION

1 PRE-INSTALLATION REQUIREMENTS

Since the SOPHIE is a very small and light-weight unit, the installation can be performed by one person only. The unit is shipped complete so there is no need to perform special assembly or calibrations on the field. The unit is normally used free-standing, and the mobile version standing on its own locked wheels, so there’s not normally any need to drill holes during the installation.

1.1Tools required

Tools for the mechanical installation

A standard set of screwdrivers (a motorized one is recommended for opening the packaging crate) and millimeter based Allen-keys is about what you need.

Other tools

Please refer to chapter “PREVENTIVE MAINTENANCE CHECKS” on page E-2 for details of test instruments needed for the installation check-up.

1.2Environmental requirements

Strength requirement for the floor

The weight of the unit (approx. 160kg) is moderate and does not cause any special requirements for the strength of the floor.

However, the floor must be straight within 0,5%. The stationary unit has four small feet in the base that can be adjusted to level the unit if the floor is uneven.

The unit should never be placed on thick carpets for stability and reliability reasons. Antistatic floor materials should be preferred.

Temperature & Humidity

The operating temperature range is from +15°C to +35°C, non condensing. The acceptable humidity range is from 25% to 75%. The storage temperature range is from 0°C to +45°C.

NOTE	If the unit has been stored at temperatures under +10°C for more than a few hours, time
	must be allowed for the unit to reach room temperature before turning it on.

1.3Space requirement

Width of door openings

The unit can be transported on its wheels through door openings that are 76 cm wide.

Minimum and recommended Height & Width

The following illustration shows the absolute minimum space requirement of the Sophie unit. The texts in the following picture indicates the minimum recommended space needed.

Technical Manual

Sophie Mammography X-ray unit B-1

Chapter B - UNPACKING & INSTALLATION

PRE-INSTALLATION REQUIREMENTS

Recommended minimum clearance above the C-ARM is 200 mm (8 inch) when the arm is in the highest possible position.

This equals a ceiling height of 2190 mm (84.3 in.)

Recommended minimum clearance around the unit (left - front - right) is >900 mm (>35.5 in.).

This equals an operating depth (from the wall) of 1500 mm (59 in.), and and operating width (side to side) of 2980 mm (117 in.)

1.4Radiation protection

The radiation safety regulations of individual countries must be complied with. Radiation protection devices should be used, as movable or stationary radiation shields. The mobile version of the Sophie has an integral radiation shield that must be attached to the unit.

Safe distances without specific shielding

A few exposures (without additional radiation shielding) can be made without exceeding the mR/ hour per month limit, if the operator distance is far enough from the unit. Please refer to local regulations. However, protective operator shielding is always recommended, and should always be used.

Wall LEAD-equivalence

The lead-equivalence of the walls in the room depends on the material used, please refer to local radiation protection regulations. A recommended safe value of the wall lead equivalence is ≥1 mm and should cover even the most strict requirements.

Movable shields

Radiation shields are also available. Please refer to the “SPARE PARTS MANUAL”.

1.5Power requirement

Mains voltage & frequency

Nominal operating voltage can be from 208-240 V~, single phase, either between the phases or between one phase and neutral. The built in line voltage compensation ensures proper operation within ±10% fluctuation (187-265 V~). The mains frequency can be either 50 or 60 Hz ±10%.

Fuse ratings

The minimum recommended external fuse rating is 15 AT (time-lag). Electromagnetic circuit breakers can be used, since the unit’s power factor is >0.95. The unit is also protected internally with 15 AT fuses.

Mains impedance & earthing

To ensure proper operation over the recommended mains voltage range, the resistance of the mains should not exceed 1 Ω. The unit must be connected to an earthed outlet.

Typical power consumption

The idle power consumption is less that 100VA. The maximum power consumption is worst case 4000VA for a maximum of 5 seconds (Toshiba E7272 tube: at 27kV / 110mA exposure settings, Toshiba E7290 tube: 33kV / 97mA exposure settings.

UNPACKING THE UNIT

2 UNPACKING THE UNIT

2.1General about unpacking

Unpack the unit indoors in a convenient place, preferably as close as possible to the final installation location. The unit can be transported to the final location on its own wheels. The only limiting factors can be narrow doors or lifts and the fact that you need a mains outlet (208-240VAC) within 3 meters from the unpacking location. Unpacking the mobile version is similar to what is described below.

2.2Step-by-step unpacking instructions

a)Open and remove the 8 screws on the top of the crate cover. Lift and remove the top cover. Remove the four large Allen head bolts (item 1). Remove the accessory box from the crate.

b)Remove the 8 screws (item 2) around the base of the crate and lift the rectangular crate carefully up and away.

Please refer to the User’s manual for instructions how to insert the upper compression paddle, the lower compression paddle or the Bucky device.

3.2Remote control attachment (optional for the mobile unit)

NOTE	There are two types of the remote control box, the traditional and the extended (that has
	an additional READY-light). They unit must be programmed accordingly, depending of
	which box is in use. See paragraph “12. Setting type of remote control box” on page F-18
	for details.
	Attach the remote control box to the rear of the radiation shield to be used, or to any other conve-
	nient location that is shielded from radiation. According to local radiation safety regulations, there
	must often be a visual contact between the patient and the operator. Please take this into
	account when finding a proper location for the remote box.

	excess length. The cable should be attached to the walls or put in a cable viaduct, never let the
	cable lye on the floor where it can be damaged. Please notice that the remote cable has one
	male an one female connector. The male connector is the one that is connected to the unit.
