摘要： The disclosure relates to PET imaging systems and methods. The systems may execute the methods to obtain an anatomical image of a subject acquired when the subject remains in a breath-hold status; obtain PET data of the subject, the PET data corresponding to a respiration signal with a plurality of respiratory phases of the subject, the respiratory phases including a first respiratory phase and a second respiratory phase; gate the PET data; reconstruct a plurality of gated PET images, the plurality of gated PET images including a first gated PET image corresponding to the first respiratory phase and a second gated PET image corresponding to the second respiratory phase; determine a first motion vector field between the first gated PET image and the second gated PET image; determine a second motion vector field between the anatomical image and the second gated PET image; and reconstruct an attenuation corrected PET image.

摘要： A positron emission tomography (PET) assembly includes an annular housing and an annular scintillator disposed within the annular housing. The annular scintillator includes an annular, substantially continuous crystal scintillator tube configured to absorb ionizing radiation and to emit light energy. A plurality of photo detectors are annularly disposed around the annular scintillator within the annular housing and configured to detect the emitted light energy.

摘要： A data detection device is used in combination with a magnetic resonance imaging (MRI) apparatus. A magnetic field detection unit (34) serves to detect a temporally varying magnetic field generated by the MRI apparatus, and a timestamping unit (35) generates magnetic field detection timestamps in dependence of the detected temporally varying magnetic field. This allows determining a temporal relation to acquired MRI data.

摘要： In beta emission imaging, magnetic lensing allows a lower resolution detector to detect the spatial distribution of emissions at a higher resolution. The sample is placed in a magnetic field with field lines at a given density, and the detector is placed away from the sample where the magnet field lines diverge, resulting in a lesser density. Since the beta emissions travel along the field lines, the divergence of the field lines from the sample to the detector result in lensing or magnification. Using positron attenuation tomography to detect annihilation in the detector allows for correction due to self-absorption by the sample. The correction and lensing are used together or may be used independently.

摘要： In a PET (Positron Emission Tomography)-MRI (Magnetic Resonance Imaging) apparatus of an embodiment, a magnet that is a seamless structure generates a static magnetic field in a bore having a cylindrical shape. First detectors and second detectors are each formed in a ring shape and detect gamma rays emitted from positron emitting radionuclides injected into a subject. The first detectors and the second detectors are disposed with a space therebetween in an axial direction of the bore so as to interpose the magnetic field center of the static magnetic field therebetween.

摘要： Multi-modal imaging capsule for image-guided proton beam therapy, consisting of a biocompatible polymer layer, 18O-enriched water, and a contrast agent. The biocompatible capsule may be inserted near or inside a tumor under the guidance of X-ray, magnetic resonance, or ultrasonography imaging. Upon proton beam irradiation, the capsule emits positrons, allowing the tumor to be imaged and tracked by a PET detector.

摘要： A method for determining a position of a mobile device relative to a B0 field magnet along a z-coordinate axis, and a device and a magnetic resonance tomography unit for performing the method are provided. The device includes a magnetic field strength sensor arranged in a fixed relative position. A characteristic magnetic field strength Bref of the B0 field magnet that emerges for a plurality of x-y coordinate pairs with a same reference z-coordinate zref is ascertained. The device is moved along the z-coordinate axis until the magnetic field strength sensor measures the characteristic magnetic field strength Bref.

摘要： A set of first modality data (e.g., MR or CT) is provided. The set of first modality data comprises a plurality of mu-maps, a plurality of motion vectors and a plurality of gated data. Each of the mu-maps corresponds to one of the beds. A set of second modality data (e.g., PET/SPECT) is provided. The set of second modality data comprises a plurality of frames for each of the beds. Each of the plurality of frames is warped by one or more motion vectors of the plurality of motion vectors. A single-bed image is generated for each bed by summing the frames corresponding to the bed. A whole body image is generated by summing the single-bed images for each of the beds.
