  • Pmt signal correlation filter
    Publication number: 20060151707
    Abstract: A method of generating a filter (40) for a nuclear medicine system (20) where the filter selects valid detected radiation events for image processing. A dataset (60) is provided that is indicative of a plurality of emitted radiation events occurring over a predetermined period of time. Signals representative of the response of a detector to the dataset of the plurality of emitted radiation events are generated. A pattern is determined (66) based on a correlation of a plurality of signals resulting from the response of the detector to a plurality of single radiation events in the dataset. A filter is generated (74) based on the correlation pattern. A method and apparatus of using the generated filter is also disclosed.

  • Multimodality medical imaging system and method with separable detector devices
    Patent number: 6961606
    Abstract: The invention comprises a system and method for creating medical images of a subject patient using a plurality of imaging devices, such as tomographic imaging scanners. The imaging devices each have a bore through which a patient is translated during scanning. The imaging devices can be moved apart to allow greater access to a patient between the bores.

  • Multimodality medical imaging system and method with patient handling assembly
    Patent number: 6754520
    Abstract: The invention comprises a system and method for handling a patient in a tomographic imaging system using a plurality of imaging devices. The imaging devices each have a bore through which a patient is translated during scanning. One or more patient support structures extend from the front of the tomographic imaging system, where the patient is initially placed, through the bores of the system. The patient is translated through the bores of the system and along the patient support structures by an actuator.
