摘要： A method and apparatus is provided to reconstruct a collective image of a multiple method/geometry imaging system (e.g., a hybrid computed tomography system having energy-integrating detectors arranged in a third-generation geometry and photon-counting detectors arranged in a fourth generation geometry), wherein a splitting-based iterative algorithm using modified dual variables is used in the image reconstruction. Whereas a separate image for each method/geometry of the multiple method/geometry imaging system can be obtained by solving the distinct system-matrix equation corresponding to each respective method/geometry, the collective image is obtained by simultaneously solving a collective optimization problem including all respective system-matrix. The collective image is obtained more efficiently using variable splitting to subdivide the optimization into subproblems that are solved in an iterative fashion. For some applications, the collective image can be further improved by including a beam-hardening correction step.

摘要： With a mammography PET apparatus, a supporting face includes a detector ring region, and a detector-outside region as an outside area of the detector ring region. The detector ring region is higher than the detector-outside region. An elastic lower-layer mat is disposed on the detector-outside region. An upper-layer mat, softer than the lower-layer mat, is disposed on the detector ring region and the lower-layer mat across a boundary between the detector ring region and the lower-layer mat. Accordingly, an edge of the lower-layer mat harder than the upper-layer mat is covered with the upper-layer mat, leading to alleviation of pain to a subject M caused by the edge of the lower-layer mat.

摘要： An x-ray/gamma ray imaging apparatus includes a pixilated x-ray/gamma ray detector (3) including a member configured to detect incident x-ray/gamma ray wavelength photons, a position for a body under test (2), an x-ray or gamma ray source (1), and a structure configured to perturb the energy spectrum (6), each lying on a common axis. The source is arranged to direct an x-ray gamma ray energy spectrum along the common axis to impinge upon a structure configured to perturb the x-ray energy spectrum and a positioned body/object under test. The structure and the position for the body under test lie between the source and the detector member, and the structure includes at least three adjacent regions, each region different to immediately adjacent regions and configured to perturb the x-ray energy spectrum differently. Detected photons are subject to a random noise reduction algorithm.

摘要： A method for attenuation correction of a phantom image in a PET imaging system includes obtaining raw scan data of a scanned phantom, a non attenuation corrected template image of a stock phantom of like type to the scanned phantom, and an attenuation map of the stock phantom. The method further includes generating a non-attenuation corrected raw image of the scanned phantom based on the raw scan data, registering the template image and attenuation map to the raw image through a rigid image transform, and applying the registered attenuation map to the raw scan data to enable reconstruction of an attenuation corrected final image.

摘要： The present disclosure relates to removable, nonslip, non-adhesive coverings which are used as shelf, drawer or storage liners. In particular, the covering sheet features an improved composite material having a top decorative layer of flocked polymeric film combined to a continuous bottom layer of unsupported foam. The structure of the multilayered composite material facilitates the convenient hand tearing of the sheet to size through a grid of perforations that are obscured by a fine coating of natural or synthetic fibers.
