Patent number: 7138638Abstract: A scintillator, for use in a radiation imaging device, has a light-emitting face, a radiation receiving face, and a perimeter extending between the light-emitting face and the radiation receiving face, the perimeter including an edge, the edge having an edge thickness. The scintillator emits scintillation light from the light emitting face in response to radiation incident on the radiation receiving face. The scintillator has one or more light guides formed within a peripheral region of the scintillator proximate to the edge. The light guides can improve the positional accuracy of a radiation imaging device including the scintillator.Type: GrantFiled: November 19, 2004Date of Patent: November 21, 2006Inventor: Jack E.

Patent number: 7105825Abstract: A single photon emission computed tomography system includes a base for supporting a patient and a detector assembly adjacent the field of view. The detector assembly detects photon strikes from the field of view. A photon-blocking member is disposed between the field of view and the detector and has an aperture slot that allows passage of photons aligned with the slot. A collimating assembly includes a plurality of collimating vanes formed of photon-attenuating material. A support assembly supports the collimating assembly and includes a first support member and a second support member with the collimating assembly being disposed therebetween. An adjustment assembly includes a first adjuster operable to adjust a first distance between the collimating assembly and the first support member and a second adjuster operable to adjust a second distance between the collimating assembly and the second support member.Type: GrantFiled: June 18, 2004Date of Patent: September 12, 2006Inventor: Jack E.

Patent number: 7015476Abstract: A single photon emission computed tomography system produces multiple tomographic images of the type representing a three-dimensional distribution of a photon-emitting radioisotope. The system has a base including a patient support for supporting a patient such that a portion of the patient is located in a field of view. A longitudinal axis is defined through the field of view. A detector module is adjacent the field of view and includes a photon-responsive detector. The detector is operable to detect if a photon strikes the detector. A photon-blocking member is positioned between the field of view and the detector. The blocking member has an aperture slot for passage of photons aligned with the aperture slot. A line of response is defined from the detector through the aperture. A collimating assembly includes a plurality of generally parallel collimating vanes formed of a photon attenuating material. The vanes are spaced apart so as to find a plurality of gaps, with the gaps each having a height.Type: GrantFiled: February 5, 2003Date of Patent: March 21, 2006Inventor: Jack E. Juni

Patent number: 6525321Abstract: A single photon emission computed tomography system produces multiple tomographic images of the type representing a three-dimensional distribution of a photon-emitting radioisotope. The system has a base including a patient support for supporting a human patient such that a portion of the patient's torso is located in a field of view. The patient's torso extends generally vertically such that the patient's head is substantially higher than the patient's hips. A longitudinal axis is defined through the field of view, with longitudinal axis being generally vertical. A detector assembly is adjacent to the field of view and includes a photon-responsive detector operable to detect if a photon strikes the detector. The detector assembly is operable to scan for photons emitted from the portion of the patient's torso located in the field of view. The patient remains stationary during the scan.Type: GrantFiled: March 28, 2002Date of Patent: February 25, 2003Inventor: Jack E. Juni

The system has a base including a patient support for supporting a patient such that a portion of the patient is located in a field of view. A longitudinal axis is defined through the field of view. A detector module is adjacent the field of view and includes a photon-responsive detector. The detector is an elongated strip with a central axis that is generally parallel to the longitudinal axis. The detector is operable to detect if a photon strikes the detector. The detector can also determine a position along the length of the strip where a photon is detected. A photon-blocking member is positioned between the field of view and the detector. The blocking member has an aperture slot for passage of photons aligned with the aperture slot. The slot is generally parallel to the longitudinal axis.Type: GrantFiled: April 14, 2000Date of Patent: February 25, 2003Inventor: Jack E. Juni
