3-Dimensional Imaging of the Breast
Abstract
Initial investigations of the four proposed reconstruction methods have been delayed due to the sale of the original detector system by Thomas Jefferson University Hospital. An experimental framework for performing 3-D imaging of the breast has been developed. We have also developed and begun to characterize two detectors that will replace the detectors originally proposed for use in the grant. The first detector is an active matrix amorphous-selenium device, and second uses a phosphor screen optically coupled to a CCD camera. The first device has excellent dose efficiency (DQE) and resolution, but is too slow to allow easy tomographic imaging. The latter device again has excellent resolution, but lacks the dose efficiency of the flat panel detector. This detector does, however, have the temporal response needed to perform CT. Due to the sale of the equipment, it will be necessary to alter the original work plan. We will not be able to image surgical specimens, instead we will image mastectomy and cadaveric breast tissue.
