Abstract: A side frame for a loudspeaker rigging system has a frame structure mountable to the side of a loudspeaker, and links associated with the frame structure for linking together the corners of the frame structures of vertically adjacent side frames. The links associated with each side frame structure include a pivot link and splay adjustment link, each of which has a top extended end and a base end. Stow channels, which are preferably located in the bottom corner regions of the frame structure, contain the pivot link and splay adjustment link in the frame structure. A gripping structure associated with at least one, and preferably each link of the pivot and splay adjustment links allows a user to easily maneuver a link from its stowed to its deployed position.

Abstract: A side frame for a loudspeaker rigging system has a frame structure mountable to the side of a loudspeaker, and links associated with the frame structure for linking together the corners of the frame structures of vertically adjacent side frames. The links associated with each side frame structure include a pivot link and splay adjustment link, each of which has a top extended end and a base end with a seating edge. Guide channels, which are located in the top corner regions of the frame structure to receive the base ends of a pivot link and splay adjustment link associated with a vertically adjacent side frame, have seating surfaces that conform to the seating edges at the base ends of the pivot and splay adjustment link. When base ends of these links seat in the guide channels, pin holes in the base end of the links self-align with pin holes in the corners of the frame structure for easy insertion locking pins.

Abstract: Various embodiments of the present invention provide processes for applying deterministic radiation transport solution methods for calculating doses and predicting scatter in radiotherapy and imaging applications. One method embodiment of the present invention is a process for using deterministic methods to calculate dose distributions resulting from radiotherapy treatments, diagnostic imaging, or industrial sterilization, and for calculating image scatter for the purposes of image reconstruction. In one embodiment of the present invention, a method provides a means for transport of external radiation sources through field-shaping devices. In another embodiment of the present invention, a method includes a process for calculating the dose response at selected points and volumes prior to radiotherapy treatment planning.

Abstract: Method and system that allows patient dose response functions to be calculated, prior to treatment planning, for external photon beam radiotherapy. In one embodiment, for each location where a separate dose value is desired, referred to as a dose region, adjoint calculations are performed to calculate the adjoint solution fields associated with that dose region. Once potential beam directions are specified, a ray tracing process is performed to transport the adjoint solution fields out of the patient and to locations where treatment plan parameters may be specified. The output of this process is the dose response at each dose region resulting from a prescribed photon fluence, at a given location, direction, and energy.

Abstract: One method embodiment of the present invention is a process for using deterministic methods to calculate dose distributions resulting from radiotherapy treatments, diagnostic imaging, or industrial sterilization, and for calculating scatter corrections used for image reconstruction. In one embodiment of the present invention, the method provides a means for constructing a deterministic computational grid from an acquired 3-D image representation, transport of an external radiation source through field shaping devices and into the computational grid, calculation of the radiation scatter and/or delivered dose in the computational grid, and subsequent transport of the scattered radiation to detectors external to the computational grid.
