Hello, I am the webmaster.

According to the comprehensive medical website Medical NEWS
Tohoku University announced on January 12 that its Graduate School of Dentistry has begun joint research and development with other institutions toward the commercialization of a "dental X-ray CT system," which will make it possible to perform diagnostic examinations according to the purpose of examination with a single device (all-in-one) for dental diagnosis.

When our webmaster visited a dental clinic, he asked the dentist about it and was told that an X-ray CT for dental use currently costs about 30 million yen, so it would be difficult for an individual dentist to install one due to cost. Therefore, it is difficult for individual dental clinics to introduce it due to its cost. It would be more convenient if an inexpensive device is developed and becomes widely used.
The dentist there had an X-ray transmission device (commonly known as an x-ray), and I was shown the images, and was a bit surprised to see that the artifacts (noise) derived from the dental fillings (silver palladium) were reduced by image processing.
As a further aside, the X-ray CT used in our service costs about 100-150 million yen. In addition, it is necessary to have the skill to use it. We are looking forward to working with you.
