## Indications for Use
The MCT-1 EX F is intended to be used for three dimensional X-ray Computed The ITCT + DF + 1 to med and neck by limited cone shaped x-ray beam projected on to an FPD to be operated and used by doctors, dentists, properly licensed professionals and other legally qualified professionals.
## Device Story
MCT-1 EX F is a limited cone beam X-ray CT scanner for head and neck imaging. Device uses rotating arm and base to acquire 360-degree rotational X-ray sequences; replaces previous image intensifier (XII) with Flat Panel Detector (FPD). System reconstructs 3D matrix of examined volume; produces 2D and 3D images for diagnostic support. Operated by physicians, dentists, and technologists in clinical settings. High-resolution images obtained in short duration; compact system design; low radiation dosage. Healthcare providers use displayed images to assess complex hard tissue morphology; aids clinical decision-making for diagnosis.
## Clinical Evidence
Bench testing only. No clinical data provided. Device certified for CE marking by VDE; performance specifications compared to predicate via technical analysis.
## Technological Characteristics
Limited cone beam X-ray CT; Flat Panel Detector (FPD) image receptor; rotating arm and base mechanical structure; MCT electric circuit; compact form factor. Software is identical to predicate. Standards met include VDE certification.
## Regulatory Identification
A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

#### 6. Description of the device:
The MCT-1 EX F is an X-ray CT using the limited cone beam. MCT-1 EX F makes diagnosis be possible due to its high resolution three dimensional images for small diagnosis be possible add to the extremely complex morphology of the hard tissue of the head and neck region
High resolution images are obtained in the same short period as that of the Panoramic Radiology. Low X-ray radiation dosage is realized and the overall system structure is assembled to be compact unit.
The J.MORITA. MFG. CORP. has manufactured the MCT-1EX as the original model of such kind of X-ray scanner, and modify the device for MCT-1 EX F by replacing the image receptor , XII for FPD ( Flat Panel Detector).
### 7. Intended Use
The MCT-1 EX F is intended to be used for three dimensional X-ray Computed The ITCT + DF + 1 to med and neck by limited cone shaped x-ray beam projected on to an FPD to be operated and used by doctors, dentists, properly licensed professionals and other legally qualified professionals.
#### Safety and effectiveness of the device 8.
As the MCT-1 EX F is modified from our legally marketed device, MCT- 1 EX (K#030450) by replacing image receptor from XII to FPD with remaining all the other parts be common, so that the MCT-1 EX F is substantially equivalent to MCT-1EX as is shown in the comparison summary table below because they have . . similar general intended uses, technological characteristics and operating principles.
Any differences in the technological characteristics do not raise any new issues of safety or effectiveness.

Dear Mr. Barritt:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
