A radiologist workstation program capable of performing the methods of: (a) losslessly compressing an image by using a sample of pixel neighborhoods to determine a series of predictive coefficients values related to the pixel neighborhoods; (b) lossy compressing an image to a predetermined ratio by adjusting the quality parameter in a quality controlled compression routine; (c) adjusting the compression ratio of image data based upon the available bandwidth of a network link across which the image is transmitted; (d) encapsulating audio data in a DICOM object and selectively retrieving the data; (e) performing an improved integer based ray tracing method by establishing a ray angle from an observer position and adjusting the ray angle such that the directional components of the ray angle are rational numbers; and (f) reducing flicker caused by a magnifying window moving across an image on the display screen by determining what portion of a first window position is not covered by a new window position and restoring from memory that portion of the image which corresponds to the portion of the first window not covered by the second window.

606192, 606191, 600 37, 128898

An apparatus and method for treating morbid obesity in mammals using a gastric reduction assembly that reduces the gastric volume of a stomach and induces early satiety. The gastric reduction assembly comprises at least two or more expandable devices, each able to be adjustably inflated with a fluid (e. g. , a liquid or a gas) using a filling tube. In a preferred embodiment, the gastric reduction assembly is inserted through the abdominal wall and placed at a location exterior to the stomach body, avoiding an abdominal incision. Once positioned near the stomach body, the gastric reduction assembly allows for the external compression of the stomach body to limit food intake. The gastric reduction assembly also minimizes the potential for shifting of the expandable devices after insertion to the stomach body to revert to its pre-compressed state.
