Cutting edge image sensor technology offers significant advantages over traditional film or existing electronic imagers for dental radiography
Dental Imaging amounts to far more than ‘just’ digital X-rays, because now 3D cameras are also used in dental technology - to prepare fillings, to simulate complete jaw structures, and to replace the impression material for bridges, crowns, etc. This kind of 3D camera provides a screen image rotatable by six degrees of the relevant jaw or tooth portion, in which the dentist and dental technician can perform direct modelling, so as to achieve a perfect fit.
New combined procedures such as MRI and CT or MRI and PET provide more precise results for the determination of findings
Everyone can remember imaging techniques such as ultrasound, X-ray, CT (Computer Tomography), MRI (Magnetic Resonance Imaging), NMR (Nuclear Magnetic Resonance) or PET (Positron Emission Tomography) from their last visit to the hospital. In the X-ray area, there are CMOS image sensors for detecting X-rays. These involve a complete wafer or extremely large semiconductor dies that are used as X-ray sensors. In all the imaging systems very fast A/D converters and computationally intensive digital signal processing are required. Imaging systems also include cameras, such as those used in nevus checks in dermatological medicine. This provides digital documentation of skin changes.
Portable devices in the medical imaging area include ultrasound devices and smaller X-ray machines (mainly in veterinary medicine)
For portable ultrasound devices in particular, there are built-in front-end modules, which process a large part of the signal chain. Other portable imaging systems include endoscopes and cameras in pill form suitable for inspecting the small intestine (especially for the detection of small-bowel cancer), where the small bowel cannot be reached by normal endoscopes. Currently, such pill cameras cannot be controlled from the outside, but manufacturers of medical technology devices are already working on the next generation of externally controllable pill cameras.
