  • Patent number: 11009615
    Abstract: A time of flight (TOF) positron emission tomography (PET) image (38) is generated from TOF PET imaging data (10) acquired of a subject using a TOF PET imaging data acquisition device (6). Iterative image reconstruction (30) of the TOF PET imaging data is performed with TOF localization of counts along respective lines of response (LORs) to iteratively update a reconstructed image (32). Values for at least one regularization or filtering parameter are assigned to the TOF PET imaging data or to voxels of the reconstructed image based on an estimated TOF localization resolution for the TOF PET imaging data or voxels. Regularization (34) or filtering (36) of the reconstructed image is performed using the assigned values for the at least one regularization or filtering parameter. In some embodiments, the varying TOF localization resolution for the TOF PET imaging data or voxels is estimated based on related acquisition characteristics such as count rates or operating temperature of the detectors.

  • Patent number: 10740877
    Abstract: Patient imaging systems, such as PET imaging systems, for example, may suffer from the introduction of artificially introduced noise. This noise is, typically, introduced during iterations of reconstruction algorithms, such as the least-squares algorithms, which attempts to recreate a 2D or a 3D image from raw acquisition information. The noise appears as “hot-spots” in the reconstructed image. Approaches to address these artefacts use filtering approaches. Typically, a least-squares reconstruction is supplemented with a penalty term, an approach known as “Relative Difference Penalty”. The penalty parameter causes the reconstruction algorithm to filter more or less strongly at certain regions of the reconstruction. The present application proposes an approach which supplements the penalty term with continuous probability information about the likelihood of an edge being present in a portion of an image.

  • Publication number: 20200008770
    Abstract: A respiratory motion signal generation method operates on emission data (22) of an imaging subject in an imaging field of view (FOV) acquired by a positron emission tomography (PET) or single photon emission computed tomography (SPECT) imaging device (10). An array of regions (32) is defined in the imaging FOV without reference to anatomy of the imaging subject. For each region of the array of regions defined in the imaging FOV, an activity position versus time curve (54) is computed from the emission data acquired by the PET or SPECT imaging device. Frequency-selective filtering of the activity position versus time curves is performed to generate filtered activity position versus time curves. At least one motion signal (66) is generated by combining the filtered activity position versus time curves of at least a selected sub-set of the regions.

  • Publication number: 20190355158
    Abstract: Imaging data (20) are acquired by a PET scanner (6) or other imaging device. Iterative image reconstruction of the imaging data is performed to generate a reconstructed image (22). The iterative image reconstruction includes performing an update step (24) that includes an edge preserving prior (28) having a spatially varying edge preservation threshold (30) whose value at each image voxel depends on a noise metric (32) in a local neighborhood of the image voxel. The noise metric may be computed as an aggregation of the intensities of neighborhood image voxels of the reconstructed image in the local neighborhood of the image voxel. The edge preserving prior may be a Relative Difference Prior (RDP). For further noise suppression, during the iterative image reconstruction image values of image features of the reconstructed image that have spatial extent smaller than a threshold (38) may be reduced.

  • Patent number: 10448909
    Abstract: The invention relates to a combined imaging detector (110) for the detection of x-ray and gamma quanta. The combined imaging detector (110) is adapted for simultaneous detection of gamma and x-ray quanta. The combined imaging detector (110) includes an x-ray anti-scatter grid (111), a layer of x-ray scintillator elements (112), a first photodetector array (113), a layer of gamma scintillator elements (114), and a second photodetector array (115) that are arranged in a stacked configuration along a radiation-receiving direction (116). The x-ray anti-scatter grid (111) comprises a plurality of septa (117A, B, C) that define a plurality of apertures (118) which are configured to collimate both x-ray quanta and gamma quanta received from the radiation receiving direction (116) such that received gamma quanta are collimated only by the x-ray anti-scatter grid (111). The use of the x-ray anti-scatter grid as a collimator for received gamma quanta results in a significantly lighter combined imaging detector.

  • Publication number: 20190046137
    Abstract: The invention relates to the detection of x-ray and gamma quanta. In the medical imaging arrangement (100) an x-ray source (111) is attached to a first portion of an x-ray c-arm (113) and an x-ray detector (112) is attached to a second portion of the x-ray c-arm (113) for measuring x-ray transmission along a path (115) between the x-ray source and the x-ray detector. A gamma camera (114) is movable along a trajectory (116) that intersects the path between the x-ray source and the x-ray detector. Since the gamma camera can be moved along a trajectory that intersects the path between the x-ray source and the x-ray detector, the gamma camera can be used to generate a nuclear image that closely corresponds to the same region of interest as that which is imaged by the x-ray source and detector.

  • Patent number: 9619905
    Abstract: A method of image reconstruction corrected for attenuation is provided for use with radioemission-based imaging, such as SPECT and PET. This method includes collecting measured emission projection data. The emission projection data, a reconstruction of the emission projection data, and a priori organ information are collectively analyzed to generate a body region estimate of the imaged subject. Each voxel of the body region estimate is then homogenously assigned an attenuation coefficient to generate an initial attenuation map estimate. An initial emission assumption is also generated based on a reconstruction of the emission projection data. The initial emission assumption and initial attenuation map estimate are then processed and refined to produce an image reconstruction.

  • Patent number: 8977027
    Abstract: 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.

  • Publication number: 20150003591
    Abstract: Nuclear Imaging System The invention relates to a nuclear imaging system (1) for imaging an object (3) in an examination region. Multiple x-rays sources (2) generate first radiation being x-ray radiation (5), wherein the x-ray sources are arranged such that the x-ray radiation is indicative of a property of the object. A detection unit (6) detects second radiation (7) from a nuclear element (8), after the second radiation has the traversed the object, and the first radiation generated by the multiple x-ray sources, thereby inherently registering the detection of the first radiation and the second radiation. A reconstruction unit (9) reconstructs a corrected nuclear image of the object based on the detected first radiation and the detected second radiation, wherein the nuclear image is corrected with respect to the property of the object and, because of the inherent registration, does not comprise image artifacts caused by registration errors.

  • Publication number: 20120278055
    Abstract: A diagnostic imaging system includes a tomographic scanner 10 which generates sets of anatomical and functional image data. An adaption unit 50 adapts a motion model to a geometry of an object of interest based on a motion averaged volume image representation acquired over a plurality of motion phases. Virtual image data is simulated from the anatomical projection image data with the motion model at the plurality of motion phases. A comparison unit 54 determines a difference between the actual and virtual anatomical image data. If the difference meets a stopping criterion, the motion model is used to correct acquired functional image data, and a corrected functional image is reconstructed therefrom. If not, the motion model is iteratively updated based until the difference meets the stopping criterion.
