    摘要： Disclosed herein are methods and devices for the acquisition of positron emission (or PET) data in the presence of ionizing radiation that causes afterglow of PET detectors. In one variation, the method comprises adjusting a coincidence trigger threshold of the PET detectors during a therapy session. In one variation, the method comprises adjusting a gain factor used in positron emission data acquisition (e.g., a gain factor used to multiply and/or shift the output(s) of a PET detector(s)) during a therapy session. In some variations, a method for acquiring positron emission data during a radiation therapy session comprises suspending communication between the PET detectors and a signal processor of a controller for a predetermined period of time after a radiation pulse has been emitted by the linac.

    摘要： A particle beam rotational irradiation apparatus of the present invention is purported to place in a frame, even in the case of a corkscrew type, a movable floor that is retractable at the time of movement of an irradiation nozzle. According to the particle beam rotational irradiation apparatus (20) of the invention, it is characterized by including: a frame (2) that supports an irradiation nozzle (1) and rotates; an irradiation-nozzle support member(12) that is provided on an inner-circumference side of the frame (2) and supports the irradiation nozzle (1); a movable floor (3) that has a roller (6) movable in a circumferential direction centering on a rotation axis of the frame (2); and a movable-floor rail (7) that is provided in the circumferential direction on the inner-circumference side of the frame (2) and supports the roller (6); wherein the irradiation-nozzle support member (12) and the movable floor (3) have their respective coupling portions (9) that are attachable/detachable to/from each other.

    摘要： Brachytherapy seed insertion and fixation devices and systems to decrease implanted brachytherapy seed migration within tissue and minimize trauma. Component(s) with cavity or opening features are attached to a brachytherapy seed or series of seeds. The cavity or opening features interact with the patient's tissue to fix the seed and component assembly in place and inhibit movement/migration of the seed(s). The cavity or opening features may optionally be filled with an adhesive or other beneficial material. The seed(s) or seed and component assembly may be inserted using a delivery device having a needle through which the seed(s) or assembly are implanted and a stylet extending through the needle to cut tissue and facilitate insertion of the needle. The stylet has a reduced diameter cutting tip to cut a narrow hole in tissue, and a tapered region that stretches the narrow hole to accommodate insertion of the larger diameter needle.
