• Attributes: 3rd-Party Reviewed

Intended Use

CSTC is intended to display the body and patient table beyond the normal field of view. Images generated by this software are not to be used for diagnostic purposes. Standard distance measurements are allowed.

Device Story

CSTC-002A is a software option for the TSX-201A Aquilion LB CT system; expands visualization of body and patient couch beyond standard CT field of view (FOV) from 70 cm to 85 cm. Operates as post-processing tool; images generated are explicitly non-diagnostic; allows standard distance measurements. Used in clinical radiology settings by trained CT technologists/radiologists. Output provides extended anatomical context for positioning or planning; does not replace diagnostic imaging. Benefits include improved visualization of patient anatomy and table positioning within the scanner bore.

Clinical Evidence

No clinical data. Device is a software modification to an existing cleared CT system; substantial equivalence supported by design and performance characteristics.

Technological Characteristics

Software-based post-processing option for CT imaging. Operates on TSX-201A Aquilion LB CT system. Conforms to IEC 60601-1, IEC 60601-2-32, and IEC 60601-2-44. Complies with 21 CFR Subchapter J (Federal Diagnostic X-ray Equipment Standard).

Indications for Use

Indicated for use as a post-processing software option for the TSX-201A CT system to increase image information from a 70 cm field of view (FOV) to an 85 cm FOV.

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.

#### Description of this Device:

The CSTC-002A will be added to the previously cleared TSX-201A Aquilion LB CT system. This addition requires software modifications to the existing device. Addition of this option will allow for visualization of the body and patient couch beyond the normal field of view.

## Summary of Intended Uses:

CSTC is intended to display the body and patient table beyond the normal field of view. Images generated by this software are not to be used for diagnostic purposes. Standard distance measurements are allowed.

# Technological Characteristics:

This package is similar in uses and applications as those of the predicate devices. The main difference is in the method used to obtain the final results.

{1}------------------------------------------------

## Safety and Effectiveness Concerns:

This device is designed and manufactured under the Quality System Regulations as outlined in 21 CFR § 820. All requirements of the Federal Diagnostic Equipment Standard, as outlined in 21 CFR § 1020.30 and 1020.33, that apply to this upgrade, will be met and reported via a supplement to the initial report for the predicate device. Additionally this system is in conformance with the applicable parts of the IEC 60601-1 {applicable portions}; IEC 60601-2-32, and IEC 60601-2-44. Medical Device Safety standards.

### Substantial Equivalence:

This package provides similar tools to those found in the predicate device. This package does not provide new indications or functions when compared to those that are already available in products already being marketed.
