K-FILTER FOR SERIAL HIGH-SPEED ROTATOGRAPHY, AND APPARATUS FOR THE ROTATOGRAPHY.

摘要

A K-filter (1) is the one attached to an apparatus for serial high-speed rotatography for photographing a specimen by use of X rays. The filter comprises two K-containers (5a and 5b) in which a space is defined for fluidly containing a fluid substance transmitting no radiation, and a radiation permeable 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 an inversion type which allows the radiation permeable 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 potographing is started.
