#### 8. System requirements to operate with other radiographic system components
- 1) Recommended Generator Specification:
Energy range: 40~150kVp
mA range: 10~1000mA (depending on the generator power)
ms range: 10~6300ms to produce 0.1~1000mAs (depending on the generator power) Note: To our best knowledge, the detector is compatible with the X-ray generators with the specifications described above. If you have any questions regarding the compatibility issue for other generators, please contact the distributor or iRay's service office.
- 2) Application Program Interface (API) for system integration manufacturer Peripheral hardware: Mars1717X connected via wireless communication.
| Operating System: | Windows XP/7/8/10, 32/64bit |
|-------------------|------------------------------------------------------------------------|
| CPU: | Intel Core i7 3.6G |
| Memory: | 4G DDR3 |
| Hard Disk: | 640 G |
| LAN Card: | Intel Pro EXP9301CT PRO<br>Gigabit Network Adapter with PCIe interface |
#### 3) X-ray exposure mode
The AED trigger module is a unit can connect X-ray signal in the Mars1717X. Once there is X-ray generator exposure exist, the AED trigger module will detect the X-ray radiation and output signal to the detector. Until the exposure finished, the detector will receive a signal which represent the end of exposure from the inner trigger module and begin to acquire the image.
### 9. Substantial Equivalence [21 CFR 807.92(b)(1) and 807.92(b)(2)]

# 8 of 10
{11}------------------------------------------------
Electrical, mechanical, environmental safety according to IEC/ES 60601-1 was performed, and EMC testing was also conducted in accordance with IEC 60601-1-2. All test results are meet the standard requirements.
- 2) Biological Evaluation:
The materials of the detector which contact operators' or patient's skin have been evaluated with the ISO 10993-1. And the evaluation results and test result assured the safety the same as the predicate device.
- 3) Non-clinical Considerations:
One main modification from the predicate device is Amorphous Silicon (a-Si) panel size design, related to Amorphous Silicon (A-Si) panel size. Another modification is structure design with thinner panel thickness, higher IP grade and surface pressure performance.
The non-clinical studies have been performed and the results have shown that sections of the non-clinical consideration mentioned in the 'Guidance for the Submission of 510(k)s for Solid State X-ray Imaging Devices' are substantially equivalent to the non-clinical consideration of predicate devices on the Market (Mars1717V-VSI, K201043).
- 4) Clinical Consideration:
Intended use, fundamental scientific technology, regulatory requirement, non-clinical performance, labeling, quality-assurance program and software keep the same with those of predicate device. Additionally, as mentioned in clinical considerations in 'Guidance for the Submission of 510(k)s for Solid State X-ray Imaging Devices', clinical consideration may not necessary for changes in the dimensions of the image receptor with otherwise identical materials if non-clinical information is sufficient to support the substantial equivalence.
