A heel effect compensation filter is configured to have a thickness distribution that uniforms an X-ray intensity angular distribution that is nonuniform in the body axis direction of a subject in an X-ray flux irradiated space. The space is formed by an X-ray flux diverging from an anode in a body width direction of the subject and diverging in a shape of an approximate sector in the body axis direction due to the heel effect, when the X-ray flux generated on the anode by irradiating a thermoelectron beam flux from a cathode to the anode is irradiated on the subject. The thickness distribution can be obtained using a predetermined formula.       Recently Added Patents Resin composition, prepreg, resin sheet, metal-clad laminate, printed wiring board, multilayer printed wiring board and semiconductor device Piano keyboard with key touch point detection Optical multiplexer/demultiplexer Device for increasing chip testing efficiency and method thereof Driver circuit for driving semiconductor switches Isolated SCR ESD device Data architecture and user interface for plasma processing related software applications   Randomly Featured Patents Appliance knob Multiphase Coriolis flowmeter Biocompatible absorbable polymer plating system for tissue fixation Tomographic apparatus and method Tire with rubber sidewall Radio telephone in which an off operation of an operator-activated power switch is inhibited during a talk mode Method of etching magnetic layer, of forming magnetic pole of thin film magnetic head and of manufacturing thin film magnetic head Passage width adjusting device for a sliver trumpet Portable radio equipment having a display Cosmetic container © 2006-2008 PatentGenius.
