#### 8) Device Description

The RADspeed Pro is an X-ray radiography system that is mainly used for the radiography of various regions of the patient's body in a standing or recumbent position. The RADspeed Pro can be used in a wide range of applications from general radiography using X-ray film or Computed Radiography (CR) cassettes, to digital radiography. The RADspeed Pro consists of an X-ray high voltage generator, X-ray tube unit, X-ray tube support and collimator. The system can be configured with radiographic table, radiographic stand and digital radiography system as well.

Optionally, the device is also used to perform tomosynthesis radiography by three different reconstruction modes. Filtered Back-Projection (FBP) mode is used to obtain a tomosynthesis image by performing back-projection after correcting the projection data. Shift Addition (SA) mode is used to obtain a tomosynthesis image at an arbitrary slice plane height by shifting each image according to projection angle of the tube based on the reconstruction height, and by applying image addition processing to them. Iteration (IR) mode is used to reduce metal artifact in tomosynthesis image. FBP mode is generally recommended for all body parts. In case an artifact is observed at joints and other similar places, SA mode may remedy this artifact. In case metal artifact is obviously displayed. IR mode is recommended to reduce metal artifact.

#### 9) Intended Use

The RADspeed Pro is a stationary X-ray system for taking general radiographic and tomographic images of the whole body. The device is intended to be used in hospitals, clinics, imaging centers, and/or other healthcare facilities by qualified/trained professionals.

{6}------------------------------------------------

SECTION V:

# 510(k) Summary

# Software Verification and Validation Testing

Digital radiography system is using similar, but different software processing method. Therefore, Software Risk Analysis and Verification and Validation testing were conducted as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" and "Content of Premarket Submissions for Management of Cybersecurity in Medical Devices" to assure substantial equivalence.

As a result, we identified the level of concern associated with new device and provided documentation consistent with that level. Based on our risk analysis of software, the difference does not affect its safety and effectiveness.

# Non-clinical Performance Testing

For the difference of software processing methods which is different from primary predicate device, we performed non clinical performance testing between new device and predicate devices, in accordance with the FDA Guidance "Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging(SSXI) Devices" issued on Aug. 6, 1999.

We conducted performance bench test and image quality evaluate substantial equivalence of image processing technique to each predicate device respectively.

We also performed phantom tests using several different anatomical body phantoms.

For Dual Energy Subtraction, additional test report was submitted to assure the distinction of lesion overlying bones to calcification or tubercle shade.

For metal artifact reduction function of tomosynthesis option, we conducted performance testing. The result indicates that both FBP(filtered back-projection) mode and IR(Iteration) mode of new device has a same level of metal artifact reduction capability as the mode with artifact reduction of its predicate device.

We performed a U.S. board-certified radiologist review of the anthropomorphic phantom images of tomosynthesis reconstruction. The review covers an evaluation of each reconstruction mode of new device for each anatomies. As a result, the review supports that new device is substantially equivalent in its image quality of tomosynthesis reconstruction as compared to its predicate devices. SA (Shift Addition) mode is acceptable as a traditional image, however, it is suggested that SA mode is used together with FBP or IR mode, whenever available.

Considering all these aspects, the result of non-clinical performance data demonstrates substantial equivalence of new device to the predicate devices in aspect of image acquisition, image processing as well as image quality capabilities.

SECTION V:

510(k) Summary

# Clinical Performance Testing

The result of non-clinical bench testing demonstrates substantial equivalence to the predicate devices. Therefore, it is our understanding that clinical testing is not required in this case.

# Radiation safety

New device and primary predicate device is substantially equivalent by their conformities of CFR and IEC60601-1-3.

# 13) Conclusion

The non-clinical data support the safety of the device and the hardware and software verification and validation demonstrate that new device should perform as intended in the specified use. Based on our risk analysis and bench testing, the differences do not affect its clinical safety or effectiveness.

From the result of our risk analysis, software verification and validation, and nonclinical testing discussed above, it is our conclusion that,

- -New device is substantially equivalent to the legally marketed predicate devices, K093427 FDR ACSELERATE SYSTEM, DR-ID 200 FLAT PANEL DETECTOR, K121499 FUJIFILM Tomosynthesis Option for FDR ACSELERATE STATINOARY X-RAY SYSTEM, K101686 FDR IMAGE STITCHING OPTION and K122454 FUJIFILM DUAL ENERGY SUBTRACTION (DES) SOFTWARE OPTION.
- Additional Indication for Use of new device does not introduce any new safety and effectiveness concern.
- Therefore, new device is as safe, as effective, and performs as well as or better than the predicate device(s).
