Operation Manual
1.5.3 Principle of Radiographic
Panoramic modes
Keep pressing the X-ray Exposure switch to rotate the arm unit. The X-ray tube assembly
that irradiates a narrow beam is suspended to the arm unit. The arm unit rotates at a
speciedspeedaroundthestationarypatient.Duringthearmunitrotation,datawillbe
acquired by the Sensor unit multiple times. In the image processing unit, data acquired in the
Sensor unit are superimposed with the shift value according to the desired tomographic area
to acquire tomographic view.
TMJ mode
In the same manner as that in the panoramic mode, the patient can be positioned within
theeldofradiographictoacquireonlytheimagesofleftandrightjointareasnecessaryfor
diagnosis.
Cephalometric radiography (*)
Aplainradiographicimagewithstablemagnicationpercentageoftheproperlypositioned
patient's head, between the narrow beam irradiating X-ray generator and the Cephalometric
sensor which is the optical receiver, can be acquired.
Carpus radiography (*)
Aplainradiographicimagewithstablemagnicationpercentageoftheproperlypositioned
patient's hand, between the narrow beam irradiating X-ray generator and the Cephalometric
sensor which is the optical receiver, can be acquired.
3D image acquisition (**)
Keep pressing the X-ray Exposure switch. Irradiate from the X-ray generator which rotates
around the stationary patient. The X-ray which passes through the patient is detected by the
3Dsensor.ReconguretheimagebycomputerusingtheX-rayabsorbeddatadetectedto
acquire tomographic view.
* Caution
• Errors may be observed when measurement is made on 2D images acquired in the
panoramic mode.
* For equipment with Cephalometric
** For equipment with 3D function
