摘要： A framework for predicting mechanical failure. The framework may acquire vibration data from the at least one vibration sensor in a medical device. The vibration data may be pre-processed to generated pre-processed data. An onset of failure of the medical device may then be predicted based on the pre-processed data.

摘要： For ultrasound imaging with an ultrasound scanner, fat fraction of the tissue is measured. The fat fraction may be measured without access to channel data, such as from beamformed data. The speed of sound varies with the fat fraction of tissue, so the fat fraction is used to set the speed of sound in beamforming. Imaging the tissue using the fat fraction-based optimization for speed of sound may provide better images than imaging with an assumed speed.

摘要： A multi-modality imaging system allows for selectable photoelectric effect and/or Compton effect detection. The camera or detector is a module with a catcher detector. Depending on the use or design, a scatter detector and/or a coded physical aperture are positioned in front of the catcher detector relative to the patient space. For low energies, emissions passing through the scatter detector continue through the coded aperture to be detected by the catcher detector using the photoelectric effect. Alternatively, the scatter detector is not provided. For higher energies, some emissions scatter at the scatter detector, and resulting emissions from the scattering pass by or through the coded aperture to be detected at the catcher detector for detection using the Compton effect. Alternatively, the coded aperture is not provided. The same module may be used to detect using both the photoelectric and Compton effects where both the scatter detector and coded aperture are provided with the catcher detector. Multiple modules may be positioned together to form a larger camera, or a module is used alone. By using modules, any number of modules may be used to fit with a multi-modality imaging system. One or more such modules may be added to another imaging system (e.g., CT or MR) for a multi-modality imaging system.

摘要： For predicting stroke risk, an artificial intelligence rapidly generates flow information from input of geometric parameters of a carotid of a patient. An image processor predicts the stroke risk from the flow information. In one approach, the values of the geometric parameters of the carotid of the patient are perturbed based on uncertainty. The artificial intelligence generates candidate flow information for each perturbation. The candidate flow information sufficiently matching a measurement of flow for the patient is used as the flow information for stroke risk prediction.

摘要： A neural network (16) operating on volume data and using convolutional layers (24) may better classify conversion or Alzheimer's disease. The neural network (16) may be trained to operate on incomplete data. The neural network (16) may have a branching architecture (30-34) for more accurate classification given a variety of types of available data (20, 21) for a given patient.

摘要： A cooling channel in a gantry of a medical imaging apparatus transfers heat away from the radiation detector and detector electronics, while limiting influence on magnetic fields generated within the gantry, when incorporated in a magnetic resonance imaging (MRI) system. The cooling channel includes a non-electrically conducting, non-metallic housing in conductive thermal communication with the detector electronics and the radiation detector. A cooling conduit in the housing circulates coolant fluid. A unitary, non-electrically conductive, non-metallic heat sink in the housing is in direct conductive, thermal communication with the housing and the cooling conduit. A solid, thermally conductive layer is interposed between and affixed to opposing, spaced exterior surfaces of the conduit and the heat sink.

摘要： For transducers with a chip-on-array arrangement, the dematching layer extends beyond a footprint of the array, allowing for connection of the grounding plane without sidewall metalization. The flexible circuit material is tiled, reducing thermal deformation, reducing cost, and increasing process yield. The dematching layer extension and the tiled flexible circuit may be used together or individually in a given transducer.

摘要： A method for generating transmission information in a time-of-flight positron emission tomography (PET) scanner having a patient tunnel and a plurality of PET detector rings. The PET scanner uses continuous bed motion to move a patient bed and patient through the patient tunnel. The patient receives a positron-emitting radioisotope dose prior to undergoing a PET scan. The method includes storing a positron-emitting radioisotope in a radiation shielded container. The method also includes moving the radioisotope into a stationary vessel located adjacent to the PET detectors and within a field of view of the PET scanner at substantially the same time that the patient receives the radioisotope dose to form a stationary transmission source wherein transmission information is generated while the bed undergoes continuous bed motion. Further, the method includes withdrawing the radioisotope from the vessel when the PET scan is complete and storing the radioisotope in the container.
