Publication number: 20220155471Abstract: A time of flight positron emission tomography (TOF PET) detector comprises a direct conversion semiconductor crystal (e.g. CZT), cathode and anode disposed on respective first and opposite second faces of the crystal, and a timing circuit operatively connected to generate a trigger signal in response to absorption of a 511 keV gamma ray by the direct conversion semiconductor crystal. The timing circuit generates the trigger signal with jitter of 500 picoseconds or lower. One or both of the cathode and/or anode is a blocking electrode. In some embodiments, the cathode is a single continuous electrode, the timing circuit is operatively connected with the cathode, the anode comprises an array of electrode pixels disposed on the second face of the direct conversion semiconductor crystal, and a sense circuit is operatively connected with the electrode pixels of the anode. TOF PET scanners including such detectors are also disclosed.Type: ApplicationFiled: March 17, 2020Publication date: May 19, 2022Inventor: Ira Micah BLEVIS

Patent number: 9753156Abstract: The invention relates to a detector (6) for detecting radiation, especially x-ray radiation used in a computed tomography system. The detector comprises a direct conversion material (9) for converting radiation into electrons and holes, which are used for generating an electrical detection signal. The direct conversion material is illuminated with illumination light being broadband visible and/or broadband infrared light for reducing, in particular, eliminating, a polarization of the direct conversion material, which may occur when being traversed by the radiation to be detected and which may reduce the detection performance. By reducing the polarization of the direct conversion material the detection performance can be improved.Type: GrantFiled: February 28, 2014Date of Patent: September 5, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Frank Verbakel, Klaus Juergen Engel, Antonius Johannes Maria Nellissen, Herfried Karl Wieczorek, Eric Cornelius Egbertus Van Grunsven, Ira Micah Blevis, Roger Steadman Booker
