发明名称 K-filter for serial high-speed rotatography and apparatus for the rotatography
摘要 PCT No. PCT/JP93/00693 Sec. 371 Date Jan. 17, 1995 Sec. 102(e) Date Jan. 17, 1995 PCT Filed May 25, 1993 PCT Pub. No. WO93/24053 PCT Pub. Date Dec. 9, 1993A K-filter is the one attached to an apparatus for serial high-speed rotatography for photographing an object to be examined by use of X-rays. The filter comprises two K-containers (5a and 5b) in which a space is defined for fluidly containing a radiopaque fluid substance, and a radiotransparent region (2) formed between the two K-containers (5a and 5b). The K-containers (5a and 5b) are pivotally supported by a supporting member (1a) and are of the inversion type which allows the radiotransparent region sides of the K-containers to move. Therefore, when this apparatus is rotated at a high speed to more than 180 DEG , it is possible to conduct filtering under any conditions such as an inclined posture, not the horizontal posture, under which photographing is started.
