Standard panoramic program
Orthogonal panoramic program
The standard panoramic program has a traditional path and angles of the beam.
The basic imaging geometry is the same as in the standard panoramic program but the X-ray beam is perpendicular to the jaw.
NOTE This program is optimized for orthogonal imaging and
a shadow of the opposite side teeth may therefore be visible in the radiograph.
Interproximal panoramic program
The basic imaging geometry is the same as in the standard panoramic program but the X-ray beam is more parallel to the interproximal contacts of the teeth.

Adjusting DEC density
CONTROL PANEL
Touch the DEC field on top of the main display to switch Dynamic Exposure Control (DEC) on or off for the exposure you are going to take.
Dynamic Exposure Control (DEC) automatically provides optimal exposure values for each patient during exposure. This function adjusts the exposure values individually for each patient based on their anatomic structure and bone density. Switching DEC on improves the image quality as the function produces images of more consistent brightness and contrast.
When DEC is switched on the exposure values will be automatically adjusted during exposure. The kV value will be adjusted by max ±4 kV and the mA value will be adjusted by max +4/-3 mA within the available scale.
If the images appear to be too bright or too dark, DEC density can be adjusted on the DEC Settings display (i25.1).
To adjust DEC density for panoramic exposures touch either of the Panoramic density arrow fields. DEC density is expressed in percentage in comparison to DEC calibration value. The setting can be adjusted between 20% (lower exposure values -> brighter image) and 200% (higher exposure values -> darker image). The recommended setting is 100% (default setting).

SINUS EXPOSURE
This procedure will produce an exposure of the maxillary sinus along the selected plane.
Insert the chin support into the adapter. Insert the adapter into the holes in the patient support table.
Select the sinus program you wish to use (see section 5.5 “Selecting sinus program” on page 25). Select the patient size (see section 5.2.1 “Selecting patient size” on page
15). The exposure values will automatically change to
correspond with the selected exposure program and patient size. The preset exposure values are shown in the following tables. The preset exposure values are average values and they are only meant to guide the user. If necessary, you can change the preset values as described in section 5.2.2 “Selecting kilovolt and milliampere values” on page 15.

10.1 Patient positioning

NOTE Always try to minimize the radiation dose to the
patient.
Move the C-arm to the patient entry position if it is not already there. Refer to section 5.2.5 “Selecting patient entry position” on page 17 for differences between the two positions.
Prepare the patient for the exposure as described in section 7.2 “Preparing patient” on page 31.
Press the temple support button to open the temple supports if they are not already open.
Guide the patient towards the unit so that they are facing the chin support.
To adjust the height of the unit, press either of the height adjusting buttons until the opening in the chin support is approximately level with the patient’s mouth.

The X-ray unit moves slowly at first, then faster.
Ask the patient to step forward, grasp the patient handles, stretch and straighten their back and neck, and press their lips against the chin support. The patient's nose must rest on top of the support and their mouth must be closed.
The positioning lights for the midsagittal plane, Frankfort plane and layer position will come on. Note that they will automatically switch off after two minutes. If the lights go out before you have positioned the patient, switch them on by touching the thumb wheel on the underside of the patient support table or by pressing any of the positioning controls (button or joystick).

Position the patient’s head so that the midsagittal plane coincides with the midsagittal light beam.
Position the patient’s head so that the Frankfort plane is tilted up between 0 and 30 degrees depending on the build of the patient. To do this support the back of the patient’s head with your hand and, using the Frankfort plane light as a reference line, adjust the tilt of the patient’s head by raising or lowering the unit with the height adjusting buttons. The patient’s back and neck should be straight.
User’s Manual (2D)
The Frankfort plane light, which is located on the side of the column, can be moved up or down. This is done by rotating the thumb wheel below the light slot.
NOTE Make sure that you have selected the right patient and
the panoramic exposure mode in the Planmeca Romexis program before you take an exposure. Refer to the Romexis User’s Manual.

10.2 Taking an exposure

When you are ready to take an exposure touch the Ready field on the main display. The X-ray unit will move to the ready position and the temple supports will automatically close.
On the exposure button and on the control panel a green indicator light will come on. Additionally, the word READY will be shown on the control panel display. The Romexis program will show the Waiting for Ready message on the computer screen.
The green indicator lights and the word READY will flash while the unit moves to the ready position. They will stop flashing when the unit has reached the ready position. The Romexis program will now show the Waiting for Exposure message on the computer screen.
Ask the patient to swallow and stand as still as possible.
Move to a protected area.
Press and hold down the exposure button for the duration of the exposure. The C-arm will move through one complete exposure cycle. During the exposure cycle the radiation warning lights on the exposure switch and on the control panel will come on and you will hear a radiation warning tone. When the C-arm has completed the exposure cycle the temple supports will automatically open. You can now guide the patient from the unit.
NOTE Maintain audio and visual contact with the patient and
unit during exposure. If the C-arm stops moving during exposure, or moves in an erratic way, release the exposure button immediately.
When you have taken the exposure the image will be shown on the computer screen. Note that you must accept the image in the Planmeca Romexis program ­only accepted images will be stored in the database. Refer to the Romexis User’s Manual.
