    摘要: A contrast medium injector for injecting a patient with contrast medium for a CT scan is programmed to provide an injection protocol that is a representation of an ideally defined exponential curve with an initial injection rate decaying at an exponential rate. This has been found to produce a uniform vascular enhancement for the scanning of a patient's blood vessels. The particular exponential decay coefficient which has been found to be optimal is directly proportional to the cardiac output divided by the patient's weight and is approximated at 0.01 for a typical human.

    摘要: Text is rendered to a television screen using only the alpha channel. This is accomplished by delaying blending with underlying video until the end of the process to thereby preserve the alpha channel information. Glyphs are used to graphically represent character data in the text to be rendered. Glyphs can be stored in a character texture. In addition, the glyphs can be contained in rectangles having identifiable locations in the character texture. The rectangles can have sizes dependent upon the glyph the rectangle contains.
