Patent number: 8977027Abstract: An anatomical image data set and an emission image data set are acquired for a subject. An attenuation map is generated from the anatomical image data set. The emission image data set is reconstructed to generate an emission image. The reconstructing includes correcting for attenuation of emission radiation in the subject using the attenuation map. A value is calculated for a quality assurance (QA) metric quantifying alignment of the attenuation map with the emission image. The emission image is displayed or printed together with the calculated quality assurance metric. In some embodiments, prior to the reconstructing the attenuation map is registered with the emission image data set by performing a global rigid registration followed by a local non-rigid registration of a region of interest.Type: GrantFiled: August 17, 2011Date of Patent: March 10, 2015Assignee: Koninklijke Philips N.V.Inventors: Angela Da Silva, Horace Hines, Lingxiong Shao, Hongjie Liang, Anna Exner, Andreas Goedicke

Patent number: 6713766Abstract: A gamma camera is provided in which the study protocol can be modified after the study has commenced and while event data is being acquired. In such a camera, study parameters such as the duration of the study, the number of image frames acquired, or the count criterion required to produce an image may be changed dynamically as the study proceeds. Thus, a nuclear study which is seen to be leading to unsatisfactory or less than optimal results may be altered during acquisition to increase the likelihood that diagnostically useful results will be produced.Type: GrantFiled: June 28, 2001Date of Patent: March 30, 2004Assignee: Koninklijke Philips Electronics N.V.Inventors: Jody L. Garrard, Horace Hines, Hugo Bertelsen, David E. Coles, Jeffrey A. Hallett

Publication number: 20030013950Abstract: A gamma camera system is described in which counts are scatter corrected using multiple windows located in the vicinity of a photopeak. Pixel data is thereby scatter corrected prior to image formation. The system is useful-in nuclear medicine studies using dual isotopes such as stress and lung perfusion studies, wherein count data of the multiple isotopes are acquired simultaneously.Type: ApplicationFiled: June 27, 2001Publication date: January 16, 2003Inventors: David Rollo, Horace Hines, David E.

Patent number: 6410920Abstract: A method of correcting for deadtime and for emission contamination of a transmission scan in a nuclear camera system is provided. The transmission scan is used to correct positron emission tomography (PET) images for attenuation. The camera system includes two detectors and two corresponding single-photon point sources that are collimated to produce fanbeam illumination profiles. A transmission detection window and an emission contamination detection window is defined on each detector. Radiation from each source is scanned axially across the field of view of the corresponding detector in synchronization with the corresponding transmission detection window to acquire transmission projection data. The emission contamination detection windows are also scanned axially concurrently with, but offset from, the transmission detection windows to acquire emission data.Type: GrantFiled: September 21, 1999Date of Patent: June 25, 2002Assignee: ADAC LaboratoriesInventors: Lingxiong Shao, Hugo Bertelsen, Peter Nelleman, Horace Hines

Patent number: 6281505Abstract: The imaging system has two detectors which can be rotated in a circular path about an object with the angular displacement between the detectors and their radial position with respect to the axis being adjustable. Preferably, the distance of the detectors from the lateral axis is adjustable to increase resolution of the system. A gantry has supports for drive gear rings for the detectors with radial motion mechanisms connecting one detector to the interior surface of a drive gear ring and the other to the exterior of its drive gear ring via a support arm. A drive gear and idler gear move one detector along the circular path and a radial drive motor moves the detectors radially with respect to the axis.Type: GrantFiled: December 15, 2000Date of Patent: August 28, 2001Assignee: ADAC LaboratoriesInventors: Horace Hines, Paul Hug, Mark L.

Patent number: 5760401Abstract: The present invention provides an apparatus and method for enhancing the resolution of a Positron Emission Tomography (PET) image in a Nuclear Camera System that is configurable to performs both PET and SPECT imaging. The apparatus includes a crystal that interacts with a gamma ray to create a scintillation event within the surface of the crystal. The gamma rays that impinge the crystal have an incident angle that is limited by a field of view of the crystal. Positioned behind the crystal is a detector that responds to the light photons released by the scintillation event and registers a coordinate value of the scintillation event. Coupled to the detector is a resolution enhancer that generates an in-crystal plane displacement correction value for the coordinate value registered by the detector. The in-crystal plane displacement correction value is then combined with the coordinate value to compute the actual entry point of the gamma ray into the crystal.Type: GrantFiled: April 29, 1997Date of Patent: June 2, 1998Assignee: ADAC LaboratoriesInventors: Peter Nelleman, Hugo Bertelsen, Horace Hines

Patent number: 5444252Abstract: An improved image acquisition system allows the angular displacement between two detectors to be adjusted between 90.degree. and 180.degree. to reduce the imaging time for both 360.degree. and 180.degree. scans. A patient table is displaced vertically and horizontally from a lateral axis to allow the body of a patient to be positioned next to the detectors and to improve resolution.Type: GrantFiled: November 18, 1993Date of Patent: August 22, 1995Assignee: Adac LaboratoriesInventors: Paul Hug, Horace Hines, Mark L.
