Indications for Use
B-CAD is a computer-aided detection (CAD) software application designed to assist radiologists to analyze breast ultrasound images. B-CAD automatically segments and classifies shape and orientation characteristics of user-selected regions of interest (ROI). The software allows the user to annotate, tag, measure, and automatically record selected views. The software automatically generates reports from user inputs annotated during the image analysis process. An output may be viewed and sent to standard film or paper printers or sent electronically to an intranet web server or other DICOM device. The software may retrieve archived reports from a web server or other DICOM device. B-CAD includes the option to add annotations based on the ACR-BI-RADS® Breast Imaging Atlas. In addition, the report form has been designed to support compliance with the ACR-BI-RADS® Ultrasound Lexicon Classification Form. When interpreted by a skilled physician, this device provides information that may be useful in screening and diagnosis. Patient management decisions should not be made solely on the results of B-CAD analysis. The ultrasound images displayed on B-CAD must not be used for primary diagnostic interpretation.
Device Story
B-CAD is a CAD software application for breast ultrasound analysis. Input: digital ultrasound images. Operation: user selects region of interest (ROI) via seed point; software performs automated segmentation and classification of shape/orientation using multivariate pattern recognition. Output: segmented views, measurements, annotations, and automated reports. Used in clinical settings (PACS, standalone PC) by radiologists. Workflow: images pushed from ultrasound imager; radiologist reviews, annotates, and tags views; software generates reports based on ACR-BI-RADS lexicon. Output viewed on monitor, printed, or sent via DICOM. Benefits: assists radiologist in standardized analysis and reporting of breast ultrasound findings.
Clinical Evidence
Bench testing only. The device underwent software design, verification, and validation testing. Risk assessment was performed to identify and control potential hazards associated with quantification results. No clinical study data provided.
Technological Characteristics
Software-based CAD application. Operates on Windows 2000/XP platforms. DICOM-compatible. Uses multivariate pattern recognition for tissue segmentation and classification. Standalone or PACS-integrated deployment. No specific hardware materials or energy sources defined as it is a software-only device.
Indications for Use
Indicated for use by radiologists to assist in the analysis of breast ultrasound images. Provides information for screening and diagnosis; not for primary diagnostic interpretation. Patient management decisions should not be based solely on device output.
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).

#### 4. Device Description:
B-CAD is a computer-aided detection (CAD) software application, designed to assist radiologists to analyze breast ultrasound images. B-CAD automatically segments and classifies shape and orientation characteristics of user-selected regions of interest (ROI). The device uses multivariate pattern recognition methods to perform tissue segmentation and classification of images.
For breast ultrasound, these pattern recognition methods are used by a radiologist to analyze such features as shape and orientation [refer to American College of Radiology's (ACR) Breast Imaging Reporting and Data System (BI-RADS®) Breast Imaging Atlas and ACR-BI-RADS® Ultrasound lexicon].
The software application consists of proprietary software developed by The Medipattern Corporation. The software is a Windows 2000/XP, DICOMcompatible platform that may be installed on a standalone PC, PACS, or embedded in software applications cleared for use in medical imaging. The B-CAD user interface is designed to follow typical clinical workflow patterns to process, review, and analyze digital images.
The Medipattern software is designed to be compatible with any of the DICOM-compliant medical devices distributed by various OEM vendors.
To initiate B-CAD analysis and processing, images are acquired and pushed to the software application from an ultrasound imager for review and further analysis on a monitor. The user selects a ROI by clicking on a seed point and dragging the cursor to the selected boundary of the ROI. A circle appears, defining the region of interest. Once the ROI is selected, the B-CAD software initially displays a gallery of up to six segmented views on the monitor. The user may select any view for further analysis of anatomy and pathology. The software allows the user to annotate, tag, measure, and automatically record selected views. Results of the analysis are displayed on the monitor and may be selected by the user for automated reporting.
The software application automatically generates reports from user inputs annotated during the image analysis process. The user may select inputs for the report from various pull-down menus and toggle buttons and the user may direct the B-CAD software to prepopulate various fields contained in the report. All fields may be modified by the user at any time during the analysis and prior to archiving.
