Methods and apparatus for determining brain cortical thickness. One method includes determining an intensity profile at each of a plurality of cortical surface points of an imaged brain using brain tissue image data and calculating a cortical thickness based on a parametrically determined transition point of each intensity profile.

A laminated sheet, particularly suitable for use in TFT fabrication, and a method for manufacturing it. The laminated sheet includes a flexible substrate, a rigid carrier, and a laminate. The method for manufacturing it involves the steps of outgassing the laminate, forming a laminated sheet by laminating the flexible substrate to the rigid carrier by means of the laminate, and degassing the laminated sheet.

A method and system for efficient synthesis of photorealistic free-form knitwear, where a single cross-section of yarn serves as the basic primitive for modeling entire articles of knitwear. This primitive, called the lumislice, describes radiance from a yarn cross-section based on fine-level interactions, including occlusion, shadowing, and multiple scattering, among yarn fibers. By representing yarn as a sequence of identical but rotated cross-sections, the lumislice can effectively propagate local microstructure over arbitrary stitch patterns and knitwear shapes. This framework accommodates varying levels of detail and capitalizes on hardware-assisted transparency blending. To further enhance realism, a technique for generating soft shadows from yarn is also introduced.

A The medical diagnostic imaging apparatus includes a source (12) for generating x-rays, an image receptor (26) for receiving the x-rays and generating image data, and an image processing subsystem (6) for generating corrected image data from the image data acquired by the image receptor. The image processing subsystem includes a processor (46) that is programmed to generate noise image data (54) by high-pass filtering (52) uncorrected diagnostic image data acquired by the image receptor, to determine statistical data (64, 66) from a first subset (56) of the noise image data, and to correct a subset (36) of the uncorrected diagnostic image data based on the statistical data, the subset of the uncorrected diagnostic image data corresponding to the subset of the noise image data.

A CT scanner (10) for obtaining a medical diagnostic image of a subject includes a stationary gantry (12), and a rotating gantry (14) rotatably supported on the stationary gantry (12) for rotation about the subject. A plurality of temporally displaced volume images are gathered, divided into slices, and stored in slice memories (541, 542, . . . 54n). A slice comparitor (58) compares each slice to a selected reference slice. The slices are transformed by a slice transformer (60) to align the slices thereby correcting for movement of the subject over the scan period.

A deck chair assembly includes a body. A first supporting member is mounted on an underside of a first end portion of the body. At least one second supporting member is mounted on an underside of a mediate end portion of the body. A third supporting member is mounted on an underside of a second end portion of the body. A first L-shaped member includes a horizontal portion fitted in a first end of the third supporting member. A second L-shaped member includes a horizontal portion fitted in a second end of the third supporting member. A first positioning member includes a first outer sleeve mounted on a first leg of the first supporting member, at least one second outer sleeve mounted on a first leg of the second supporting member, and a third outer sleeve mounted on a vertical portion of the first L-shaped member. A second positioning member includes a fourth outer sleeve mounted on a second leg of the first supporting member, at least one fifth outer sleeve mounted on a second leg of the second supporting member, and a sixth outer sleeve mounted on a vertical portion of the second L-shaped member.

A portable and collapsible bed includes a generally rectangular tubular frame and an inflatable mattress with the inflatable mattress having a connecting means that has loose flaps extending towards the periphery of the hollow main flexible body with the flaps having connectors on the ends thereof which can be connected to the tubes of the tubular frame. The tubular frame is formed in a plurality of sections that are easily separable and can be collapsed to a small fraction of the overall size of the unit while the air mattress, in a deflated condition, remains supported on the frame. The unit also includes an inflating unit that can be converted to a deflating unit without any extraneous tools.
