Perimeter Medical Imaging AI, Inc. announced the expansion of its ongoing pivotal study to include an additional clinical trial site at Baylor College of Medicine in Houston, TX, under the direction of Dr. Alastair Thompson, Principal Investigator of the study. A multi-center, randomized, two-arm clinical trial is underway to measure the effectiveness of the Perimeter B-Series OCT imaging platform combined with ImgAssist artificial intelligence (AI) technology in reducing the number of unaddressed positive margins in breast lumpectomy procedures when used in addition to standard intraoperative margin assessment. Approximately 300 patients undergoing breast conservation surgery across eight U.S. clinical sites are expected to participate in the pivotal trial, with study completion anticipated by the end of 2022.
