Intended Use

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.

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.

Indications for Use

Indicated for measurement of carotid artery far and near wall intima-media thickness (IMT) from ultrasound images to assist physicians in assessing cardiovascular risk in patients.

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).

Predicate Devices

• M'Ath® Std (K040686)
• SonoCalc™ (K030223)

#### 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.

- Data Translation images converted to BMP .

## 8. Performance Testing

As an indicator of measurement repeatability, data collected using Prowin™ As an marcator of model the coefficient of variation to be <1%.

#### 9. Conclusions

Based on available information, Prowin™ is substantially equivalent to predicate devices for viewing carotid ultrasound images and measuring prodicate are and thickness. The Prowin™ software application has the same intended use and incorporates the same basic features and benefits of the described predicate devices cleared through premarket notification without raising any new issues of safety or effectiveness.
