The Trophy Radiologie digital imaging kit is now designed for use with the following panoramic X-ray units : OP100, manufacturer Instrumentarium, K912893 ; OrthoSlice OS1000, manufacturer ASAHI, K991455 pending ; Panoura Ultra, manufacturer YOSHIDA, K number unknown to us ; X-Caliber, manufacturer ASAHI, K number unknown to us. The image generated is displayed on a computer monitor and can replace the conventional film for primary diagnostic purpose. The image can then be archived through computer storage and archival means. Referal copies of the image can be obtained with optional hard copy systems.
Not Found
The provided text is a 510(k) clearance letter from the FDA for the DIGIPAN Digital Kit for Panoramic X-Ray and its Indications for Use. It does not contain specific details about acceptance criteria, device performance studies, sample sizes, expert qualifications, or ground truth establishment.
The document states that the device is "substantially equivalent" to legally marketed predicate devices. This means that the FDA's decision was based on a comparison to existing devices, not necessarily on a de novo study proving specific performance metrics against pre-defined acceptance criteria.
Therefore, many of the requested details cannot be extracted from the provided text.
Here is a summary of what can be inferred or directly stated from the document, with the understanding that most of the requested information regarding a detailed study is not present:
1. Table of acceptance criteria and the reported device performance
- Cannot be provided from the text. The document does not define specific acceptance criteria or report performance metrics (e.g., sensitivity, specificity, spatial resolution, contrast resolution). The clearance is based on substantial equivalence to predicate devices, implying that its performance is considered comparable enough for its intended use.
2. Sample size used for the test set and the data provenance
- Not mentioned. The document does not describe a test set or its provenance.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not mentioned. The document does not indicate that a ground truth was established by experts for a test set.
4. Adjudication method for the test set
- Not mentioned. No adjudication method is described.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- No. This device is a "Digital Kit for Panoramic X-Ray," which digitizes existing panoramic X-Ray units to replace conventional film. It is not an AI-based diagnostic tool, and therefore an MRMC study comparing human readers with and without AI assistance is not applicable or discussed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not applicable/Not mentioned. As noted above, this is a digital imaging kit, not an AI algorithm. No standalone algorithm performance is discussed.
7. The type of ground truth used
- Not mentioned. No specific ground truth methodology is described. The basis for clearance is substantial equivalence to predicate radiography devices, implying that the diagnostic capability of the images produced is considered equivalent to those from conventional film.
8. The sample size for the training set
- Not mentioned. The document describes a "digital imaging kit," not a machine learning algorithm that requires a training set.
9. How the ground truth for the training set was established
- Not applicable/Not mentioned. No training set or ground truth establishment for a training set is discussed.

K991912 DIGIPAN Digital Kit for Panoramic X-Ray Dated: June 3, 1999 Received: June 7, 1999 Regulatory Class: II 21 CFR 872.1800/Procode: 90 EHD
Dear Ms. Marie-Pierre Labat-Camy:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 dass 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 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4613. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification"(21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or (301) 443-6597, or at its internet address "http://www.fda.gov/cdrh/dsma/dsmamain.html".
