The Prowin™ software program is a Windows-based application used on a personal computer intended for viewing carotid ultrasound images and measuring arterial wall thickness. It is specifically indicated for the measurement of carotid artery far and near wall intima-media thickness (IMT) from images obtained from an ultrasound system. A physician may use this information in conjunction with other medical data in the assessment of a patient's cardiovascular risk.
Prowin™ is a software program designed to measure carotid artery intimamedia thickness from ultrasound images. Prowin™ operates on a stand-alone personal computer running a Microsoft Windows™ operating system. Carotid artery images from any ultrasound machine are transferred to the computer running Prowin™ by way of any media. Following the transfer of images, Prowin™ uses proprietary, patent-pending algorithms to measure intima-media thickness (IMT) of the near and far walls of the carotid artery. The Prowin™ software also has the capability to generate a report indicating the IMT value.

§ 892.2050 Medical image management and processing system.
(a)
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.(b)
