Intended Use
The PEDRA Digital Flat Panel X-ray detector is indicated as a digital imaging solution designed for the general radiographic system for human anatomy. It is intended to replace film or screen-based radiographic systems in all general-purpose diagnostic procedures. It is not to be used for mammography.
Device Description
The PEDRA are wired or wireless digital flat panel detectors that have been designed for a faster, more streamlined approach to digital stationary X-rav systems. The PEDRA detector utilizes a combination of propriety TFT glass and scintillators (CsI / Gadox), and those and electronics are housed in one package. The detectors support an auto-trigger signal sensing technology that allows the detectors to be used without generator integration. The flat panel sensors of the PEDRA are fabricated using thin-film technology based on amorphous silicon technology. Electronically, the sensors are much like conventional photodiode arrays. Each pixel in the array consists of a light-sensing photodiode and a switching Thin Film Transistor (TFT) in the same electronic circuit. Amorphous silicon photodiodes are sensitive to visible light, with a response curve roughly comparable to human vision. The sensitivity of amorphous silicon photodiodes peaks in green wavelengths, well-matched to scintillators such as CSI and Gadox. The response has the excellent linearity of a charge-integrating-biased photodiode. SDK-Pedracalib(DMS) is the software of Detector that performs image acquisition, image correction, and pre-processing. An x-ray generator (an integral part of a complete diagnostic x-ray system) is not part of this submission.
More Information

No
The document describes standard digital X-ray detector technology and image pre-processing, with no mention of AI or ML algorithms for image analysis, interpretation, or other functions.

No
The description states the device is "indicated as a digital imaging solution designed for the general radiographic system for human anatomy" and "intended to replace film or screen-based radiographic systems in all general-purpose diagnostic procedures," which means it's used for diagnosis, not therapy.

Yes
The "Intended Use / Indications for Use" states that the device "is intended to replace film or screen-based radiographic systems in all general-purpose diagnostic procedures."

No

The device description clearly states it is a digital flat panel detector utilizing hardware components like TFT glass, scintillators, electronics, and amorphous silicon technology. While it includes software for image processing, it is an integral part of a physical hardware device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. These tests are performed outside of the body (in vitro).
  • Device Function: The PEDRA Digital Flat Panel X-ray detector is a component of a general radiographic system. Its function is to capture X-ray images of the human anatomy within the body. It does not perform tests on biological samples.
  • Intended Use: The intended use clearly states it's for "digital imaging solution designed for the general radiographic system for human anatomy" and "intended to replace film or screen-based radiographic systems in all general-purpose diagnostic procedures." This describes an in-vivo imaging device, not an in-vitro diagnostic device.

The device is an in-vivo imaging device, specifically a digital X-ray detector.

Table 2. Comparison of Proposed Device to the Reference Device

The proposed device is substantially equivalent to the predicate device and the reference device as part of the complete imaging system.

It is substantially equivalent to these devices in design, function, materials, operational principles, and intended use. The proposed device, PEDRA has been tested for electrical safety, EMC, and performance, and the software has been validated.

7

The differences between the subject device and the predicate device are the size of the detector, and the availability of wireless module of the subject device is compared with the reference device. As a result of verification, it was confirmed that there is no difference in other performance. Therefore, the difference in the size of the detectors does not affect the safety and effectiveness. The wireless module performed substantially equivalently in comparison with the reference device.

These differences do not raise new questions of safety and effectiveness for the subject device.

7. Non-clinical test summary

The PEDRA complies with voluntary standards for electrical safety, electromagnetic compatibility. The

following data were provided in support of the substantial equivalence determination:
