  • Patent number: 7932498
    Abstract: A method for optimizing the scanning trajectory of a radiation detector device, e.g., a SPECT scanning device, about an object generally includes: obtaining object image data using a different imaging modality, e.g., a CT scanning device, determining a maximum object boundary based on the image data, calculating an optimal scan trajectory of the SPECT scanning device relative to the object based on the maximum object boundary, scanning the object with the SPECT scanning device along the optimal scan trajectory to detect gamma photons emanating from the object, from which an image can be reconstructed from the detected gamma photons. Preferably, the SPECT device includes at least two detectors arranged at a pre-selected angle relative to one another and the optimal scan trajectory minimizes the distance between the detectors and the object while maximizing the geometric efficiency of the detectors relative to the object.

  • Patent number: 6904161
    Abstract: A computer-implemented method and apparatus is provided for workflow configuration and execution in medical imaging. One method embodiment comprises the steps of creating and storing a workflow template (the workflow template comprising a standard form for entering data and activities), filling out the workflow template with data and a sequence of activities, and executing the sequence of activities according to the workflow template.
