Abstract
According to one embodiment, an X-ray diagnostic apparatus includes a first arm, a second arm, an imaging system and a slide mechanism. The first arm rotates by a first rotating shaft and slides along with a first arc-like slide axis relatively to the first rotating shaft. The second arm rotates by a second rotating shaft fixed to the first arm and slides along with a second arc-like slide axis relatively to the second rotating shaft. The imaging system includes an X-ray generating part and an X-ray detector. The X-ray generating part and the X-ray detector are attached to the second arm. The slide mechanism slides the first arm along with the first slide axis. The slide mechanism is arranged at a position having an offset from the first rotating shaft.
Claims12
An X-ray diagnostic apparatus comprising:
- a first arm rotating around a first rotating axis and sliding along a first arc-like rail relatively to the first rotating axis;
- a second arm rotating around a second rotating axis fixed to said first arm and sliding along a second arc-like rail relatively to the second rotating axis;
- an imaging system including an X-ray generating part and an X-ray detector, the X-ray generating part and the X-ray detector being attached to said second arm;
- a slide mechanism sliding said first arm along the first rail, said slide mechanism being arranged at a position having an offset from the first rotating axis;
- and
- a control circuit configured to control the first arm and the second arm by switching between a first mode and a second mode, wherein
- each of the first arm and the second arm are independently started to move and stop relative to each other in the first mode, and
- the first arm and the second arm are moved interlocking with each other in the second mode.
An X-ray diagnostic method comprising:
- driving a first arm rotating around a first rotating axis and sliding along a first arc-like rail relatively to the first rotating axis;
- driving a second arm rotating around a second rotating axis fixed to said first arm and sliding along a second arc-like rail relatively to the second rotating axis;
- imaging an object using an imaging system including an X-ray generating part and an X-ray detector, the X-ray generating part and the X-ray detector being attached to said second arm;
- and
- controlling the first arm and the second arm by switching between a first mode and a second mode, wherein
- each of the first arm and the second arm are independently started to move and stop relative to each other in the first mode,
- the first arm and the second arm are moved interlocking with each other in the second mode, and
- said first arm is slid along the first rail by a slide mechanism arranged at a position having an offset from the first rotating axis.
An X-ray diagnosis apparatus comprising:
- a first arm rotating around a first rotating axis and sliding along a first arc-like rail relatively to the first rotating axis;
- a second arm rotating around a second rotating axis fixed to said first arm and sliding along a second arc-like rail relatively to the second rotating axis;
- an imaging system including an X-ray generating part and an X-ray detector, the X-ray generating part and the X-ray detector being attached to said second arm;
- a slide mechanism sliding said first arm along the first rail, said slide mechanism being arranged at a position having an offset from the first rotating axis;
- and
- a holding part for holding the second rotating axis, said holding part being connected with said first arm in a side surface side of said first arm which does not intersect the first rail.
