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. ## Device Story Prowin™ is a Windows-based software application for personal computers; processes carotid artery ultrasound images to measure intima-media thickness (IMT). Input: ultrasound images transferred via various media (JPEG, BMP, TIFF, DICOM). Operation: proprietary algorithms identify arterial walls; software calculates IMT for near and far walls; generates reports. Usage: clinical setting; operated by physicians or trained personnel. Output: IMT values and reports used by physicians to assess cardiovascular risk. Benefit: provides objective, repeatable measurements (coefficient of variation <1%) to support clinical decision-making regarding patient cardiovascular health. ## Clinical Evidence Bench testing only. No clinical trials or patient studies were conducted. Performance was validated through measurement repeatability testing, demonstrating a coefficient of variation of <1%. ## Technological Characteristics Software-only device; runs on standard Windows-based personal computers. Supports JPEG, BMP, TIFF, and DICOM (DIC, DCM, ACR) image formats. Proprietary algorithm for automated IMT measurement. Standalone deployment. No specific hardware requirements beyond standard PC specifications. ## Regulatory 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). ## Predicate Devices - M'Ath® Std ([K040686](/device/K040686.md)) - SonoCalc™ ([K030223](/device/K030223.md)) - QLAB™ software package ([K021966](/device/K021966.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Date of preparation: 14 February 2005 #### 1. Submitter Medical Technologies International, Inc. ("MTI") 74-980 Highway 111 Indian Wells, California 92210 FDA Owner/Operator Number: 9062380 #### Contact Gary F. Thompson, Chairman & CEO Medical Technologies International, Inc. 74-980 Highway 111 Indian Wells, California 92210 Phone: (760) 200-1179 Fax: (760) 200-1168 Email: gthompson@i-mti.com #### 2. Device Identification Tradename: Prowin™ Common name: Medical image measurement software Classification: 892.2050 - System, Image Processing, Radiological FDA has classified these devices as Class II devices under FDA Product Code LLZ. #### 3. Substantial Equivalence MTI believes that Prowin™'s measurement of IMT is substantially equivalent to other legally marketed products, specifically Intelligence in Medical Technologies' M'Ath® Std (K040686), SonoMetric Health's SonoCalc™ (K030223) and ATL Ultrasound's (d.b.a. Philips Ultrasound) QLAB™ software package (K021966) when the latter is used for the automated measurement of carotid intima-media thickness. #### 4. Device Description 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 {1}------------------------------------------------ computer running Prowin™ by way of any media. Following the transfer of images, Prowin™ uses proprietary, patent-pending r vilowing one trailerer of attammedia thickness (IMT) of the near and argoritimins of the carotid artery. The Prowin™ software enc has the capability to generate a report indicating the IMT value. #### 5. Intended Use The Prowin ™ software program is a Windows-based application used on a Firsonal 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 (111) from in fromation in conjunction with other medical data in the assessment of a patient's cardiovascular risk. {2}------------------------------------------------ Image /page/2/Picture/4 description: The image contains two small, dark, indistinct shapes against a white background. The shapes are simple and lack detail, making it difficult to determine what they represent.
