摘要： Described herein is the use of gamma cameras in the fringe field of the MRI system. Specifically, an MR image of the breast with lesion identification is first produced. Then, a gamma camera is attached to the existing breast immobilization system for generating one or more gamma images of the breast. The gamma camera is then removed from the breast immobilization system, and a breast biopsy is performed. The gamma camera can then be used to image the biopsy cores that have been removed from the patient in order to verify that the biopsy cores are radioactive, that the biopsy cores extend from one end of the lesion to the other and have a radioactive profile in which the tip is not as radioactive as the middle, and in which the ratio of amount of radioactivity in the middle of the core to the amount of radioactivity that is present in the tip of the core can be expressed as a ratio.

摘要： A method of scanning breast tissue involves inserting an imaging element into a breast via a carrier inserted into a breast duct. The imaging element may be for example a receiver, a transmitter or a mirror. A signal is transmitted between one imaging element within the breast duct and a second imaging element outside the breast.

摘要： A patient imaging system includes a patient support table, an MRI system including a cylindrical magnet and a PET system including positron detectors mounted in a ring. The magnet defines a cylindrical bore for receiving the patient on the table where the magnet is mounted for rotation about a vertical axis on a slew ring carried on rails allowing longitudinal movement. The PET ring is mounted in the bore for longitudinal movement. The quench tube for the magnet passes through the slew ring with a rotary union at the axis. The shielding covers include a fixed upper part and a lower part which rotates about the axis with the magnet. The magnet is arranged in a two or three room diagnostic configuration in which a holding bay houses the magnet and the diagnostic patients are organized in the three rooms each cooperating with the magnet bay as the magnet is rotated.

摘要： A pendant breast imaging system that operates with a MRI system and which allows a planar gamma camera breast imaging system to be positioned away from the breast area while MRI imaging is occurring, and which then moves into breast imaging position after MRI imaging is complete, and which can again be removed from the breast area to allow intervention to occur is described. It may use various collimator or scintillator materials and designs.

摘要： A wide bandwidth, high power amplifier system for amplifying a signal in a radio frequency (RF) system in a specific bandwidth within the frequency range from 1 MHz to 100 GHz. The system includes a number of amplifier modules and an equal number of input transformers connected in series, with each input transformer providing an input signal to one amplifier module. It also includes an equal number of output transformers connected in series with each output transformer receiving an input signal from one amplifier module. The series of input transformers, the series of output transformers and the amplifier modules each provide an impedance matched approximately to the impedance of the RF system.

摘要： A signal processing system for active, environmental, electronic noise suppression is proposed. The system employs a noise sense coil outside the imaging volume to detect the environmental electronic noise, it subtracts the correlated noise in the environmental signal from the imaging signal. The noise suppression eliminates the need for the RF shield around the room containing the scanner.
