A baseball training aid includes a hollow tubular member rotatably positioned on an adjustable height stand, for use in practice batting. The hollow tubular member is adjustably positioned to guide a bat during the initial movement of the bat by the batter. The apparatus can be configured as a bat guide, as a ball support, and for aligning the batting swing of a batter. A swing tube is pivotally secured to the base of the powertube apparatus, and may be adjustably positioned in relation to the hollow tubular member. A ball may be placed upon either the swing tube or on the hollow tubular member. The apparatus improves the power developed during a swing, by guiding the initial part of a swing in a forward direction, before the bat is rotated to meet the ball. The apparatus may be adjusted to suit the height and batting stance of the batter, and the hollow tubular member may be rotatably positioned and releasably secured to suit the needs of a variety of batters. The powertube apparatus may be positioned in different ways to improve the batting skills of the batter.

A simulation/generation/verification system for blocker patterns and blockers for use in radiation therapy comprises a fluoroscopic simulator apparatus, a computer system for acquisition and processing of fluoroscopic images, a manual input device for superposing blocker pattern outlines onto such images, display and storage devices for such images, apparatus for automatic cutting of blocker contour templates, blocker patterns and blockers, and apparatus for verification thereof. The system also facilitates acquisition of compensator contours and generation of corresponding compensator filters for incorporation with blockers. The system facilitates simulation, generation, and verification of blocker patterns or blockers per se in one substantially continuous procedure that minimizes intervening manual steps, while a patient is aligned within the system during an uninterrupted session. Computer-aided and computer-controlled fluoroscope image composition, linearization, enhancement and manipulation, marking of target field, acquisition and appropriate manipulation and superposition of compensator contour information, recording of all of such information and use thereof for automatic cutting of blocker contour templates, compensator filters, blocker patterns or blockers and immediate verification thereof facilitate time and cost savings, improvement in blocker accuracy, and reduction of patient anxiety and discomfort.

A linear detector selectively detects successive line images from different angles while the linear detector and a radiation source are rotated about a patient. Radiation-transmission images are generated and detected and converted to computer-grabbed images by a computer which acquires, processes, stores and reconstructs the images. A visual monitor display reconstructs video images including a planar image and tomographic images representing sections orthogonal to the planar image. Selectively-positionable field-delineating lines corresponding to intersectional outlines between a simulation beam and the planar image are overlaid on the planar image. Beam-delineating lines are updated by the computer to correspond to intersectional outlines as the field-delineating lines are positioned.
