Intended Use

suRESubtraction Ortho software is intended to generate subtraction images and improve the visualization of contrast enhancement. The system can load two or more CT images with and without contrast enhancement. When used by a qualified physician, a potential application is to determine the course of treatment.

Device Story

SURESubtraction Ortho is post-processing software for CT systems. It takes two or more CT image datasets (one contrast-enhanced, one non-contrast) as input. The software uses registration algorithms to align the datasets and subtracts intensity values to isolate bone and contrast-enhanced structures. The output is a subtraction image that improves visualization of contrast enhancement. Used in clinical settings by physicians to aid in diagnosis and treatment planning. The device benefits patients by providing clearer visualization of anatomical structures and contrast-enhanced areas compared to standard CT images.

Clinical Evidence

Bench testing only. Performance studies compared original CT images processed with SURESubtraction Ortho versus the predicate software. Results demonstrated that the subject device successfully visualized calculated enhanced edema in varying positions and rotations and provided improved visualization of contrast enhancement compared to the predicate.

Technological Characteristics

Post-processing software for CT systems. Operates via image registration and pixel-intensity subtraction. Conforms to IEC 62304 (software lifecycle) and IEC 62366 (usability). Designed under 21 CFR 820 and ISO 13485 quality standards.

Indications for Use

Indicated for use by qualified physicians to generate subtraction images from CT datasets (with and without contrast) to improve visualization of contrast enhancement and assist in determining treatment courses for any body region containing bone.

Regulatory Classification

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.

Predicate Devices

• SURESubtraction, CKOS-001A (K051833)
• Aquilion ONE Vision, TSX-301c/1, v4.90 (K122109)

# 12. REASON FOR SUBMISSION:

Modification to an accessory software

## 13. DEVICE DESCRIPTION:

The SURESubtraction Ortho, CSSO-001A is a post-processing software that subtracts image information by comparison of two data sets, one of which is contrast enhanced. Registration software is used to match the two independent studies. This registration software has been used on Toshiba CT systems for a number of years with no adverse events reported.

## 14. INDICATIONS FOR USE:

suRESubtraction Ortho software is intended to generate subtraction images and improve the visualization of contrast enhancement. The system can load two or more CT images with and without contrast enhancement. When used by a qualified physician, a potential application is to determine the course of treatment.

## 15. SUBSTANTIAL EQUIVALENCE:

This device is substantially equivalent to SURESubtraction, the subtraction tool used for Orbital Synchronized Scan System, CKOS-001A, which was originally cleared under the premarket notification for TSX-101A/H, /i, Aquilion 64/32 SP CT Scanner 510(k), K051833. Since this clearance all Toshiba CT systems have incorporated this post processing software; the latest clearance being on the Aquilion ONE Vision, TSX-301c/1, v4.90, K122109.

sureSubtraction Ortho includes modifications to the predicate software which improves on the anatomical region with which the software can be used. This post processing software performs in a manner similar to the predicate device in that subtraction images are created which aid in diagnosis. Additionally, this software includes modifications that improve upon the visualization of contrast enhancement as demonstrated in the performance studies included in this submission.

#### 16. SAFETY:

This device is designed and manufactured under the Quality System Regulations as outlined in 21 CFR § 820 and ISO 13485 Standards. This device is in conformance with the applicable parts of the IEC62304 and IEC62366 standards. All requirements of the Federal Diagnostic Equipment Standard, as outlined in 21 CFR §1020, that apply to this device, will be met and reported via product report.

#### 17. TESTING

Risk analysis and performance testing conducted through bench testing are included in this submission. Performance studies demonstrated that resultant subtraction images produced by the software can be used to successfully visualize calculated enhanced edema in varying positions and rotations and that in comparing original CT images processed with SURESubtraction Ortho versus the predicate software, the resultant images demonstrate improved visualization.

Software Documentation for a Moderate Level of Concern, per the FDA guidance document, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices Document" issued on May 11, 2005, is also included as part of this submission.

## 18. CONCLUSION

SURESubtraction Ortho, CSSO-001A, performs in a manner similar to the predicate device in that subtraction images are created which aid in diagnosis. Based upon the data presented in this submission including conformance to standards, application of design controls and performance data, Toshiba America Medical Systems, believes that SURESubtraction Ortho, CSSO-001A, is substantially equivalent in safety and effectiveness to the predicate device.
