摘要： A spot-film device includes an inner carriage whose three members are movable with respect to an outer carriage to provide a cassette tray that will accommodate varying cassette sizes. After insertion of a cassette, the inner carriage automatically contracts to a clamping position and is then movable longitudinally of the table to provide selective placement of the cassette for x-ray exposure. Lateral movement for that purpose is brought about by movement of the outer carriage. A single motor is used to provide both longitudinal clamping and longitudinal transport of the cassette while another motor provides both lateral clamping and lateral transport thereof. The lateral drive mechanism also provides for automatic ejection of a cassette after exposure.

摘要： A focusing apparatus is provided for facilitating the adjustment of the focus for a fixed optics, folded collimating lens in an X-ray imaging system. An idler member is gear driven by an adjustment knob, and is threaded to receive a mating threaded portion of the collimating lens. The collimating lens is constrained from rotating by set screws on horizontal arms which bear on a stationary bushing. Rotation of the adjustment knob thereby causes rotation of the idler member while the collimating lens is restrained from rotating. This results in straight vertical movement of the collimating lens, up or down, until optimum focus is achieved. The set screws also provide for fine rotational alignment of the collimating lens with an image head.

摘要： In the exemplary embodiment, a method is provided for transporting a source pin in a Positron Emission Tomography (PET) system. The PET system includes a storage device, a transmission ring, and a source pin loader. The method includes aligning the transmission ring and the source pin, linearly moving the source pin to the transmission ring, and operatively engaging the source pin in the transmission ring.
