PowerLook Density Assessment V4.0

PowerLook Density Assessment V4.0 is an adjunctive software application that automatically analyzes synthetic 2D images derived from Digital Breast Tomosynthesis (DBT) exams to provide a BI-RADS 5th Edition breast density category, aiding healthcare professionals in assessing breast tissue composition. The system employs a new, independently developed algorithm running on the PowerLook AMP platform, processing DICOM data from compatible Hologic and GE DBT systems to deliver consistent density assessments, including for GE V-Preview V4.1 data.

PowerLook Density Assessment V4.0 is a software application developed by iCAD, Inc., designed to assist healthcare professionals in evaluating breast tissue composition. It processes synthetic 2D images generated from Digital Breast Tomosynthesis (DBT) mammography exams, specifically those containing up to four such views, using an algorithm to assess these images and assign a breast density category according to the BI-RADS® 5th Edition lexicon. This tool provides adjunctive information, not a diagnostic aid, and is intended to support radiologists in their interpretation process. The V4.0 iteration features a new custom software application designed for the PowerLook AMP platform and includes validated support for GE V-Preview V4.1 images, distinguishing it as a new and independent application from its predecessor, V3.4. The software integrates with iCAD’s PowerLook DICOM server platform (PowerLook AMP) for managing data input and output. The results, which include the BI-RADS category and a 'fractional indication of distance inside breast density category,' can be displayed on mammography review workstations, mammography reporting applications, radiology information systems (RIS), or printed case reports. PowerLook Density Assessment V4.0 is compatible with specific DBT systems, namely Hologic Selenia Dimensions/3Dimensions (C-View), GE Senographe Essential with SenoClaire (V-Preview), and GE Senographe Pristina (V-Preview). Non-clinical performance data from verification and validation testing, including unit, integration, and regression testing on Hologic C-View, GE V-Preview V3, and GE V-Preview V4.1 cases, demonstrated that the system accurately calculates the BI-RADS breast density category for these datasets.

• Q1. How does the performance of PowerLook Density Assessment V4.0, specifically its accuracy in BI-RADS categorization, compare when processing synthetic 2D images from different DBT vendor systems (Hologic C-View, GE V-Preview) and varying image acquisition parameters?; What are the specific algorithmic differences in V4.0 compared to V3.4, particularly in its ability to process GE V-Preview V4.1 data, and how do these changes affect the precision of density boundary determination within BI-RADS categories?; What is the clinical utility and impact of the 'fractional indication of distance inside breast density category' output, and how does it influence radiologist confidence or subsequent patient management recommendations compared to a simple BI-RADS category assignment?; Are there known limitations or types of breast tissue characteristics (e.g., presence of implants, extensive calcifications, architectural distortion) where PowerLook Density Assessment V4.0's accuracy might be compromised, and what are the recommended workflows in such scenarios?; How does the integration of PowerLook Density Assessment V4.0 with the PowerLook AMP platform affect workflow efficiency and data integrity in a typical radiology practice, and what are the system requirements for optimal performance?
