Abstract: A system and method to perform motion tracking and motion-corrected image reconstruction in the field of medical imaging in general and Positron Emission Tomography in particular.

Abstract: In accordance with at least one disclosed embodiment, an apparatus for use in imaging the human brain by describing the distribution of radiotracers in the human brain is provided. The apparatus may be compact and lightweight enough to be lifted by hand (less than 50 pounds) and affixed to a patient bed. In addition, the apparatus may collect images of both the cerebrum and cerebellum of the patient.

Abstract: A method and apparatus for marking a lesion in a body part is provided. The method includes the steps of obtaining a first nuclear-emission image of the body part; determining a position of the lesion from the first image; percutaneously introducing a cannula to the determined position; inserting a wire into the cannula, the wire including radioactive material; retracting the cannula while holding the wire in place; and obtaining a second nuclear-emission image of the body part. The second image includes data relating to a position of the lesion and data relating to a position of the wire.

Abstract: An apparatus and a method for implementing emission tomography of a compressed and/or immobilized body part with open access for interventions, such as biopsy, hook-wire placement, or minimally invasive therapy, are provided. The apparatus includes one or more holders that compress and/or immobilize the body part on one or more sides of the body part. One or more of the holders contains an aperture through which an intervention can be carried out. Affixed to one or more holders are mechanical stages that carry and move a gamma-ray detector or detectors across the body part, so that the gamma-ray detector(s) can at times stay on the mechanical stages in a position that does not interfere with interventions through the aperture in the body part holder(s). A safety door mechanism is affixed to the aperture in the body part holder(s) in order to prevent the gamma-ray detector(s) from coming into physical contact with one or more portions of the body part that might otherwise protrude through the aperture.
