摘要： The connections among a plurality of dynamic image generating means, a plurality of work stations, a plurality of temporary storage means and a plurality of video tape recorders are switched from one to another a matrix switcher, so that the number of the video tape recorders may be smaller than the total number of the dynamic image generating means and the work stations. The dynamic image generating means are connected via the temporary storage means to the video tape recorders, and the video tape recorders are connected via the temporary storage means to the work stations, so that wait time at the time of image recording or reproduction can be shortened.

摘要： An X-ray diagnostic apparatus repeatedly radiates pulse-like X-rays, repeatedly images X-rays passing through an object to be examined at a predetermined frame period, and sequentially displays a plurality of images thus obtained repeatedly. In this invention, the exposure dose can be reduced since the number of X-ray irradiation times per unit time is set to be smaller than the number of frames to be imaged per unit time.

摘要： A stereoscopic X-ray apparatus is provided in which X-rays are irradiated from the two foci of a stereoscopic X-ray tube to an object to be examined so as to obtain images of the object picked-up in two directions and which permits the object to be stereoscopically displayed based on the two picked-up images. X-ray images having passed the object are picked-up by an image intensifier tube and a TV camera and stored into two frame memories. The two images output from the frame memories are alternately displayed on a display unit. At this time, the positional relation between the object and the X-ray tube and the positional relation between the object and the image intensifier tube set at the picking-up time are compared with those set in the standard state, the display positions of the two images are shifted in the right and left directions by the same distance equal to half the difference therebetween so as to adjust parallax of the two images which corresponds to the stereoscopy, thus making it possible to stereoscopically display the two images with the desired stereoscopy.
