Abstract

An X-ray fluoroscopic imaging apparatus executes an operation of rotating a C-arm continuously using a sequence mode function. The apparatus including a C-arm 9 that supports an X-ray tube 5 and an X-ray detector 7 facing each other, a memory storage element 37 stores a plurality of positions information relative to the C-arm 9 corresponding to an order information related to rotation of C-arm 9 to such a position as a sequence information, a touch panel 43 displays the position information included in the sequence information in parallel along the order of rotation of the C-arm 9, and a display control element 55 controls the touch panel 43 to display the next target rotation information, at which the C-arm 9 irradiates the X-ray, among the position information included is a sequence information SQ1 in a predetermined fixed region R1 of the touch panel 43.

First claim

What is claimed is:

1. An X-ray fluoroscopic imaging apparatus, comprising:
an X-ray tube that irradiates an X-ray toward a subject;
an X-ray detector is in place facing said X-ray tube and detects said X-ray transmitting said subject;
a support mechanism supports said X-ray tube and said X-ray detector to face each other and is rotatable around two respective axes that are orthogonal to each other;
a rotation position detection element that detects an information related to a position of said support mechanism as a position information;
a memory storage element that stores a plurality of positions information as a sequence information in association with information of a rotation order in which said support mechanism rotates to an appropriate position;
a position information display element that displays said position information included in said sequence information in parallel and in order of rotations of said support mechanism;
a display control element that controls said position information display element to display said position information in a predetermined fixed region of said position information display element every time when said X-ray tube irradiates said X-ray; and
wherein said position information is one of said positions information included in said sequence information and corresponds to a target position that is a position of said support mechanism that irradiates next said X-ray.

2. The X-ray imaging apparatus according to claim 1 , wherein:
said fixed region is a center region of said position information display element.

3. The X-ray imaging apparatus according to claim 1 , wherein:
said display control element controls said position information display element to display said position information corresponding to a position to which said support mechanism rotates to irradiate said X-ray following said target position at a present time adjacent to said position information corresponding to said target position displayed in said fixed region.

4. The X-ray imaging apparatus according to claim 1 , wherein:
said display control element controls said position information display element to display said position information corresponding to said position at which said X-ray is irradiated next following rotation of said latest target position of said support mechanism; and
wherein said position information corresponding to said target position of said support mechanism at said present time and said position information corresponding to said position at which said X-ray is irradiated next following said rotation of said support mechanism to said target position at said present time are adjacently displayed respectively in series.

5. The X-ray imaging apparatus according to claim 1 , further comprising:
a position information selection element that selects a predetermined number of said position information including said position information corresponding to said target position of said support mechanism at said present time from among a plurality of said positions information included in said sequence information, and
wherein said display control element controls for displaying said predetermined number of said positions information that said position information selection element selects.
