Abstract: A Positron Emission Tomography (“PET”) insert for use with a Magnetic Resonance Imaging (“MRI”) scanning device, the PET insert including a plurality of photodetector modules provided adjacent each other in an array, the plurality of photodetector modules configured for placement adjacent a body of a patient and sized to be received in a magnetic bore of the MRI scanning device with the patient, the photodetector modules providing detection of gamma annihilation photons, and a Radio Frequency (“RF”) coil provided between the patient and the plurality of photodetector modules. Each of the plurality of photodetector modules includes a pixelated scintillator array provided for alignment adjacent the patient's body, and a shielding block including silicon photomultiplier pads and passive electronic circuitry only.

Abstract: A dual modality probe is disclosed having both a gamma probe sensor and an ultrasound sensor. A dual imaging system is provided having the probe and at least one external gamma imaging detector and a data acquisition computer system for collecting data simultaneously from the gamma probe sensor, the gamma imaging detector, and the ultrasound sensor of the probe. A method for evaluating a target organ of a patient utilizing the probe and imaging system, and performing a biopsy of the organ is disclosed.

Abstract: A cooled optical light guide is provided having a conduit having a translucent top and a translucent bottom wherein at least a portion of the translucent top of the conduit is in alignment above at least a portion of the translucent bottom of the conduit. A fluid medium that is preferably cooled flows through the conduit. The optical light guide is placed between a scintillator array and an array detector. The temperature of the light that is emitted by the scintillator array is stabilized, and preferably cooled, as it passes through the translucent bottom of the conduit and through the translucent top of the conduit for detection by the array detector. A method of temperature stabilization for photomultiplier based detectors is disclosed.

Abstract: A mobile compact imaging system that combines both PET imaging and optical imaging into a single system which can be located in the operating room (OR) and provides faster feedback to determine if a tumor has been fully resected and if there are adequate surgical margins. While final confirmation is obtained from the pathology lab, such a device can reduce the total time necessary for the procedure and the number of iterations required to achieve satisfactory resection of a tumor with good margins.
