X-RAY DIAGNOSTIC APPARATUS AND CONTROL METHOD FOR X-RAY DIAGNOSTIC APPARATUS
In one embodiment, an X-ray diagnostic apparatus includes a memory and processing circuitry. The processing circuitry causes the memory to store a movement path that is defined by a combination of movements of a plurality of movable shafts of an imaging apparatus and is generated based on movements of the imaging apparatus in response to a user's operation. The processing circuitry moves the imaging apparatus in a reverse order of the movement path stored in the memory.

a memory; and
processing circuitry configured to
cause the memory to store a movement path that is defined by a combination of movements of a plurality of movable shafts of an imaging apparatus and is generated based on movements of the imaging apparatus in response to a user's operation and
move the imaging apparatus in a reverse order of the movement path stored in the memory.
2 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to move the imaging apparatus in the reverse order when an instruction to move the imaging apparatus in the reverse order is continued by the user's operation.
3 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to cause the memory to store the movement path generated based on movements of the imaging apparatus in response to a manual operation in which the user manually sets the plurality of movable shafts.
4 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to cause the memory to store the movement path generated based on movements of the imaging apparatus in response to the user's operation performed between a plurality of movements of the imaging apparatus in accordance with an auto-positioning instruction.
5 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to cause the memory to store the movement path generated based on movements of the imaging apparatus in response to the user's operation related to auto-positioning that reads out and executes a pre-registered motion setting of the movable shafts.
6 . The X-ray diagnostic apparatus according to claim 1 , wherein the plurality of movable shafts of the imaging apparatus include a plurality of movable shafts of a C-arm of an X-ray angiography apparatus and a plurality of movable shafts of a bed.
7 . The X-ray diagnostic apparatus according to claim 6 , wherein the plurality of movable shafts of the imaging apparatus further include a movement shaft of the X-ray CT apparatus with respect to the bed, the X-ray CT apparatus being moved in combination with the X-ray angiography apparatus.
8 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to move the imaging apparatus in such a manner that the forward-direction movement path is reproduced in a reverse direction.
9 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to cause the memory to store a combination of movements of the plurality of movable shafts of the imaging apparatus at predetermined time intervals as the movement path.
10 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to:
receive, as a stop position of the imaging apparatus, one position that is on the stored movement path of the imaging apparatus and is a position designated by the user; and
automatically move the imaging apparatus from an arbitrary position on the movement path to the stop position in response to a start instruction from the user.
11 . The X-ray diagnostic apparatus according to claim 1 , further comprising a display,
wherein the processing circuitry is configured to cause the display to display a pseudo image of the imaging apparatus corresponding to each position on the stored movement path as a moving image.
12 . The X-ray diagnostic apparatus according to claim 11 , wherein the processing circuitry is configured to:
cause the display to further display a seek bar that allows the user to designate a position corresponding to an arbitrary frame of the moving image as a stop position of the imaging apparatus; and
move the imaging apparatus until the imaging apparatus reaches the stop position.
13 . The X-ray diagnostic apparatus according to claim 11 , wherein the processing circuitry is configured to:
cause the memory to further store a specific position on the movement path when (a) the imaging apparatus is stopped for a predetermined time or longer, (b) X-rays are radiated, or (c) the imaging apparatus moves for a predetermined time or longer at a designated speed or slower; and
cause the display to further display the specific position on the moving image.
14 . The X-ray diagnostic apparatus according to claim 1 , wherein:
if the movement path is defined as a first path, when the imaging apparatus is moving in a reverse order of the first path, the processing circuitry causes the memory to further store the movement path in the reverse order as the second path; and
the processing circuitry can further move the imaging apparatus in a reverse order of the second path.
15 . The X-ray diagnostic apparatus according to claim 1 , wherein the processing circuitry is configured to, in accordance with a user's selection, move the imaging apparatus from a current position to a target position along a shortest path instead of the movement path stored in the memory.
16 . A control method for an X-ray diagnostic apparatus comprising steps of:
causing a memory to store a movement path that is defined by a combination of movements of a plurality of movable shafts of an imaging apparatus and is generated based on movements of the imaging apparatus in response to a user's operation; and
moving the imaging apparatus in a reverse order of the movement path stored in the memory.
