The CT Brain Perfusion for Ziostation option is intended for post-processing based on dynamic CT images continuously acquired during the injection of contrast, for the visualization of apparent blood flow in brain tissue and pictorial illustration of perfusionrelated parameters to aid in the assessment of the type and extent of cerebral perfusion disturbances.

Device Story

CT Brain Perfusion for Ziostation is an add-on software module for the Ziostation workstation. It processes dynamic CT image sequences acquired during contrast agent injection. The software performs post-processing to calculate and visualize cerebral blood flow and other perfusion-related parameters. It generates color maps and pictorial illustrations of these parameters. Used in clinical settings by trained medical professionals, the output assists clinicians in evaluating cerebral perfusion disturbances. The device does not contain physical materials; it is purely software running on standard PC hardware.

Clinical Evidence

No clinical data provided. Bench testing only.

Technological Characteristics

Software-only image processing package. Runs on standard PC hardware. Provides color mapping and quantification of perfusion parameters from dynamic CT image sequences. No physical materials or energy sources.

Indications for Use

Indicated for trained medical professionals to aid in the assessment of the type and extent of cerebral perfusion disturbances using dynamic CT images acquired during contrast injection.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

#### Dear Mr. Ball:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
