Device zeroes in on small breast tumors
Date:1/28/2008

ee-dimensional PET images of the breast. The PEM/PET system images the breast with a movable array of two pairs of two flat detection heads.

If a suspected lesion is found, a single pair of heads is then used to guide a needle biopsy of the lesion; the biopsy is performed with a person-controlled robot arm. Raylman is the author of the concept and has a patent on this idea. The system is especially useful in imaging tumors in women who have indeterminate mammograms because of dense or fibroglandular breasts.

The Jefferson Lab Radiation Detector and Medical Imaging Group, with a group member now affiliated with the University of Maryland School of Medicine, developed the detector heads with the on-board electronics, the data acquisition readout and the image reconstruction software. The imaging devices gantry and the motion-control software was developed by West Virginia University researchers.

The next steps for the team include minor improvements in the detector systems and image reconstruction software and the addition of components for taking x-ray computed tomography (CT) scans. Initial clinical trials are planned after completion of system testing.
