Guardian extends CAD collaboration with USC
Guardian Technologies International of Herndon, Va., reported that the medical imaging and informatics laboratory at the University of California (USC) in Los Angeles has extended its collaboration agreement to further validate the application of Signature Mapping computer-aided detection (CAD) technology and to develop a prototype that will serve as a model for future use by radiologists.

According to the agreement, Guardian and USC will collaborate on three specific areas for the Signature Mapping technology: breast imaging and breast cancer research; chest imaging and tuberculosis detection and monitoring; and traumatic brain injury and acute intracranial brain hemorrhaging.

USC will focus on the development and evaluation of a clinical prototype for use in mammography for the visualization of breast cancer and study the integrated use of MRI and mammography as an effective screening and diagnostic tool. In addition, USC will provide continued analytical validation of Signature Mapping as it relates to the South Florida mammography database.

USC will also support the development and evaluation of a prototype for use in screening, monitoring and staging after the detection of tuberculosis. USC’s clinical focus will be on chest x-rays, either from direct digital or scanned film.

Furthermore, USC will apply its efforts towards Signature Mapping’s application to acute traumatic brain injury with the development and evaluation of a prototype for use in detection and quantification of acute intracranial hemorrhage, with primary deployment on CT scanners. USC will also assess how the current work in multiple sclerosis and normal pressure hydrocephalus can be used for patient screening and evaluation in traumatic brain injury work that was jointly conducted last year, Guardian said.
