    摘要: Among other things, a rotatable drum for a radiology imaging modality is provided herein. The rotatable drum comprises a bore, defined by an inner circumference of a sidewall of the rotatable drum. In one embodiment, the sidewall comprises one or more apertures through which radiation may pass. By way of example, a radiation source and a detector array may be mounted outside of the bore (e.g., on an outside surface of the sidewall) and apertures in the sidewall may permit radiation to pass from the radiation source to the detector array without being attenuated by the sidewall of the drum. In another embodiment, the detector array may be comprised of a plurality of detector modules that may be individually mounted/dismounted from the rotatable drum, and in one example, may provide structural support to the rotatable drum.

    摘要: The present disclosure provides a system for mounting an x-ray tube to a gantry disk of a CT scanner. The system is designed to make lifting and handling a heavy and cumbersome x-ray tube easier for a person removing or replacing the x-ray tube in a CT scanner. The system includes a harness adapted to be secured to the x-ray tube, at least two elongated rods secured to the harness, and two elongated tracks adapted to be secured to the gantry disk such that the tracks extend generally parallel with a z-axis of the CT scanner. Each track includes a channel for slidingly receiving one of the rods. The present disclosure also provides a method of mounting an x-ray tube in a gantry of a CT scanner. The method includes securing a harness to the x-ray tube, securing elongated rods to the harness such that the rods extend parallel to an axis of the x-ray tube, attaching elongated guides to ends of the rods, inserting distal ends of the guides into channels of elongated tracks in the gantry of the x-ray scanner, and sliding the guides and the rods into the channels of the tracks. Then the guides are removed from the rods, and stops are secured to ends of the tracks to retain the rods within the channels.

    摘要: An assembly including a base and first and second spaced-apart shafts secured to the base and extending generally perpendicular to an elongated aperture of the base. A carrier includes a first support member slidingly receiving the first shaft, a second support member receiving the second shaft, and an elongated opening extending between the support members and generally perpendicular to the shafts. The elongated opening of the carrier is for aligning with the aperture of the base and an elongated slit of a collimator supported on the carrier for passage of an x-ray beam therethrough. A backlash-resistant nut assembly is threadingly received on a threaded portion of the second shaft and secured to the second support member.
