Ergonomy
Patient positioning is fast, easy, and accurate. An adjustable two-positioning chin support is used to carry out all exposure procedures. No additional positioning or measuring is required for any imaging procedure. An extremely rigid four-point head support and bite-block system holds the patient's head firmly and comfortably and allows excellent reproducibility.
A large adjustable mirror allows you to look directly at the patient and also see all the positioning lights. The positioning lights automatically come on when the cassette carriage is moved or the height of unit is adjusted. A special TMJ-positioning light makes temporomandibural joint exposures effortless.
During patient positioning the cassette carriage is moved horizontally out of the way so that you can easily see, talk to, and position the patient.
Imaging principles
CRANEX TOME uses the principle of autotomography with a spiral blurring movement. This movement, which is similar to the movement used by Soredex Scanora, is achieved by tilting and rotating the C-arm at the same time.
Wide experience using the Soredex SCANORA in university clinics and large busy x-ray centres has shown that dental tomograms taken using this method are far superior to images taken using linear tomographic techniques. In fact, for many professionals multi-directional spiral tomography is the method of choice.
System Intelligence
The control panel with its "soft touch" keys and large graphical display is the heart of the unit. As you use the unit, display messages guide you through the program menus and procedures and make sure that the correct exposure settings, layer thickness, collimator slot, secondary slit, and the chin support position is selected.
A large ergonomically positioned control panel with built-in wide-angle Electro-Luminescence graphical display centralises all controls and program information.
Imaging Programs
Taking x-ray images of the dental and temporomandibular regions is a complicated task because of its anatomic complexity and wide variety of diagnostic problems. Because the CRANEX TOME has such a wide range of programs you can approach these problems with complete confidence.
Panoramic Imaging
The first step in the examination of the patient's dental anatomy is to take a panoramic exposure. This panoramic exposure is a dental overview that serves as basis for further examinations that will be used to diagnose and treat the patient
CRANEX TOME’s panoramic picture is based on the geometry used in SOREDEX Scanora, which is world famous for the quality of its panoramic images. As well as taking standard and child panoramic exposures the CRANEX TOME can also take high-magnification panoramic exposures.
Ghost shadows in ramus area are eliminated without causing major overlapping in the premolar region. The magnification factor in the normal panoramic program is 1.3. In the magnified dental panoramic program it is 1.5. In the pediatric program the exposed area is limited, the magnification factor is 1.3.
Cross-Sectional Imaging
The cut is perpendicular to the jaw bone so that the measurements are accurate and reliable.
One (1) to four (4) cross-sectional exposures of a cut series can be taken in one group or separately per one film. The cuts in one series are parallel and located side by side.
The magnification factor in all the tomograms obtained with CRANEX TOME is 1.5.
Co-ordinate system
The panoramic image is used as a guide for location cross-sectional tomograms. The dental arch is divided into eleven basic regions. With numerous exposure possibilities for each region the whole dental arch can be accurately covered.
Temporomandibular Joints
Comprehensive Temporo-Mandibular Joint (TMJ) imaging Scanograms give an overview of the temporomandibular region and they can also be used as primary imaging method.
Lateral orientation program helps select the best projection angle for tomograms.
- TMJ-PA
- TMJ-LAT
- Corrected Lateral
Dental Scanograms
- Available for the first time in a panoramic x-ray unit.
- Scanograms are localised views produced using the same technique as panoramic imaging.
- They are recommended when the region of interest is small.
- Follow-up scanograms reveal bone integration in the region of implant sites.
