X-RAY PHOTOGRAPHING APPARATUS

Japanese Patent JP3556029

B

PROBLEM TO BE SOLVED: To accurately take an X-ray photograph by obliquely radiating X-rays for a desired time optionally timely in the state where an X-ray detector is continuously working by reconstructing an X-ray picture image by adding electric charge data read out from each of X-ray detecting elements in every X-ray detecting element.
SOLUTION: An apparatus comprises plural frame memories 4-1, 4-2,..., a memory controlling unit 3 for storing each of photographing data from the frame at the beginning time of X-ray radiation to the frame next to the finishing time of the X-ray radiation, based on X-ray signal, by selecting respectively different frame memories and an X-ray picture image reconstructing means 5 for reconstructing the X-ray picture image by performing addition processing and average processing of X-ray picture images at each image elements. Thereby, in the state where an X-ray detector 1 is continuously working, X-ray radiation can be performed for a desired time optionally timely and all of effectively photographed data are made to be rightly used under avoiding waste and accurate X-ray picture image improved in S/N ratio can be obtained.
