Abstract: A portable, padded chair made from X-ray transparent materials is used to comfortably support a patient while taking X-rays for medical diagnostic purposes. The use of X-ray transparent materials reduces the medical assistant's and patient's risk of repeated exposure to unnecessary X-ray levels. Also, the chair allows a patient to remain in a sitting or reclining position while X-rays are taken. A foot pedal and locking wheels allow for easy adjustment of the chair so that the patient is positioned comfortably and securely. A bucky tray, adjustable along the length and width of the chair, and a piano stand fixture, that attaches to the arms of the chair, are used to hold X-ray film cassettes. Additionally, the arm supports are adjustable and capable of being dropped to the side of the chair so a patient is easily transferred to and from a hospital bed.

Abstract: A subject table for a mammography apparatus has a slot for an X-ray film cassette extending therethrough, as well as a locking mechanism for the cassette arranged in the slot. The locking mechanism has a first detent and a second detent, at least one of the detents being spring-loaded such that the detents lie tightly against the narrow sides of the cassette when a cassette is introduced into the slot. In order to allow removal or replacement of a cassette with a simple manipulation, the lock mechanism has at least one arm that is spring-loaded in its longitudinal direction, and having one end provided with the first detent. The arm is displaceable in its longitudinal direction, and the second detent is displaceable perpendicularly to the longitudinal direction of the arm. When the second is removed from the cassette by an operating manipulation, the spring loading of the first detent causes the cassette to be ejected from the slot to a sufficient extent to allow it to be grasped by the operator.

Abstract: The reconstruction in Cone-beam CT scanner requires a high accuracy of the tabletop (1) position determination. In sequential as well as in helical acquisitions projection data (20) from different tabletop (1) positions are combined. Additional position markers, manufactured as insertions (10) of a contrast material relative to the material of the tabletop (1), are introduced into the tabletop (1). These insertions (10) allow the determination of the true position of the tabletop (1) from projection data. This information can be used to either control the scanner mechanics or as a correction information for the reconstruction process.

Abstract: A mobile medical image scanner and teleradiology system are incorporated into an ambulance or other vehicle to permit a patient to be diagnosed while en route to a treatment facility such as a trauma center. The system obtains medical image data while the patient is being transported in the vehicle and transmits the medical image data to a receiver at a location which is remote from the vehicle. At the remote location, the transmitted medical image data is displayed in a humanly discernable manner and interpreted by a qualified physician, who then communicates diagnostic information to the technicians in the vehicle and/or to the treating physicians at the treatment facility. By providing diagnostic information back to the treating physicians prior to the patient's arrival at the treatment facility, the patient can be routed directly to the operating room, or the intensive care unit as necessary, thereby saving valuable time.

Abstract: A folding mammography table having a folding thorax support hingedly attached to an upper base. The upper base is attached to a lower base by a means for adjusting the height of the upper base over the lower base. In use, the folding mammography table is sized to accommodate a mammography patient. Then the folding mammography table is folded down into the folded configuration, wherein the folding thorax support is disposed substantially horizontal. The mammography patient is then positioned on the folding mammography table, with one breast pendulously extending through a breast orifice in the folding thorax support. Gravity causes the breast to extend downwards, and X-rays are then taken of the breast. In folding mammography table embodiments incorporating two breast orifices, a breast orifice cover is used to block the breast orifice associated with a breast whose X-ray is not being taken, in order to prevent the non-X-rayed breast from interfering with the photography of the breast which is being X-rayed.

Abstract: The invention described herein combines the structural digital X-ray image provided by conventional stereotactic core biopsy instruments with the additional functional metabolic gamma imaging obtained with a dedicated compact gamma imaging mini-camera. Before the procedure, the patient is injected with an appropriate radiopharmaceutical. The radiopharmaceutical uptake distribution within the breast under compression in a conventional examination table expressed by the intensity of gamma emissions is obtained for comparison (co-registration) with the digital mammography (X-ray) image. This dual modality mode of operation greatly increases the functionality of existing stereotactic biopsy devices by yielding a much smaller number of false positives than would be produced using X-ray images alone.

Abstract: In one aspect, the present invention is a method for automatically positioning an object, such as a patient, on a movable table using pre-scan scout data. High and low edges and a center of the object are determined as a function of object position in a z-axis direction. At least one threshold is determined from which to determine whether to move the table. The table is automatically repositioned based on comparison of the thresholds to respective distances of the high edge, low edge and center of the object from isocenter. The above described method allows automatic and dynamic adjustment of the table height to a position that prevents over-range while allowing use of higher gains to reduce image noise.
