The summary describes standard image analysis techniques for calculating perfusion parameters from CT data and does not mention AI or ML.
No.
The "Intended Use" section states that the software "will aid in the assessment of the extent and type of perfusion... which may be related to stroke or tumor angiogenesis and the treatment thereof" but it does not directly treat or diagnose. It is an image analysis software that aids in assessment rather than providing a therapeutic function.
Yes
Explanation: The device is image analysis software that helps assess perfusion changes related to stroke or tumor angiogenesis, which are diagnostic purposes. It also takes CT images, processes them, and outputs parameters related to blood flow, blood volume etc. all of which are used in a diagnostic manner.
Yes
The device is explicitly described as an "image analysis software package" and its function is to process existing CT perfusion images to generate parametric images and perfusion-related parameters. There is no mention of any associated hardware component being part of the device itself.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that CT Perfusion 4 is an image analysis software package that processes CT Perfusion images. These images are obtained through a medical imaging procedure (CT scan) performed on the patient's body, not on a sample taken from the body.
- Input: The input is imaging data (CT images), not biological samples.
- Output: The output is processed imaging data and calculated parameters related to perfusion, displayed as parametric images.
Therefore, because the device analyzes medical images obtained directly from the patient's body rather than performing tests on biological samples, it falls outside the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
CT perfusion 4 is an image analysis software package that allows the user to produce dynamic image data and to generate information with regard to changes in image intensity over time. It supports the analysis of CT Perfusion images, obtained by cine imaging (in the head and body) after the intravenous injection of contrast, in calculation of the various perfusion-related parameters (i.e. regional blood flow, regional blood volume, mean transit time and capillary permeability). The results are displayed in a user-friendly graphic format as parametric images.
This software will aid in the assessment of the extent and type of perfusion, blood volume and capillary permeability changes, which may be related to stroke or tumor angiogenesis and the treatment thereof.

Device Description
CT Perfusion 4 is an image analysis software package that allows the evaluation of dynamic CT data following an injection of a compact bolus of contrast material, generating information with regards to changes in image intensity over time. It provides a quick and reliable assessment of the type and extent of perfusion disturbances by providing qualitative information on various perfusion related parameters. The results are displayed in a user-friendly graphic format as parametric images (single image calculated from a set of time course images at a single location).

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.(b)

510(k) #:
CT Perfusion 4 is an image analysis software package that allows the evaluation of dynamic CT data following an injection of a compact bolus of contrast material, generating information with regards to changes in image intensity over time. It provides a quick and reliable assessment of the type and

extent of perfusion disturbances by providing qualitative information on various perfusion related parameters.
The results are displayed in a user-friendly graphic format as parametric images (single image calculated from a set of time course images at a single location).
Indications for Use:
CT perfusion 4 is an image analysis software package that allows the user to produce dynamic image data and to generate information with regard to changes in image intensity over time. It supports the analysis of CT Perfusion images, obtained by cine imaging (in the head and body) after the intravenous injection of contrast, in calculation of the various perfusion-related parameters (i.e. regional blood flow, regional blood volume, mean transit time and capillary permeability). The results are displayed in a user-friendly graphic format as parametric images.
This software will aid in the assessment of the extent and type of perfusion, blood volume and capillary permeability changes, which may be related to stroke or tumor angiogenesis and the treatment thereof.
Comparison with Predicate:
CT Perfusion 4 images as compared with the CT Perfusion 2 device are obtained by CT scanning after an injection of contrast media. CT Perfusion 4 is a software post-processing device and as such does not affect the dosage characteristics or the imaging performance of GEMS CT scanners. The algorithms used to calculate the perfusion parameters are similar to CT Perfusion 2 device. The functional features of the CT Perfusion 4 software package are substantially equivalent to that of the following device:

Adverse Effects on Health:
The potential hazards are identified in a risk management summary (hazard analysis) and are controlled by:
- · Software Development, Validation and Verification Process to ensure performance to specifications, Federal Regulations and user requirements.
- · Adherence to industry and international standards.
Conclusions:
CT Perfusion 4 does not result in any new potential safety risks and performs as well as devices currently on the market. GE considers features of the CT Perfusion 4 to be equivalent to those of CT Perfusion 2 (K010042).
