New results for polycrystalline HgI2 detectors are reported here. Due to its decent electrical properties and high stopping power for X-rays and gamma rays, HgI2 is a good candidate for many medical imaging applications. HgI2 were deposited by a hot wall Physical Vapor Deposition (PVD) method, and the electrical properties of the films, including X-ray response and dark current data are reported. Results of imaging capabilities and spatial resolution obtained by polycrystalline HgI2 deposited onto a 2'x2' TFT imaging array on an amorphous silicon substrate are also given. These tests were carried out at Xerox-PARC Research Center.
