Three-dimensional angiography enabled by rotation of the C arm at a speed of up to 40 degrees per second. Toshiba's unique radiography sequence offers everything a radiologist requires. LAO/RAO rotation and CRA/CAU rotation are both possible without changing the C arm for rotational angiography. In addition to the usual rotational DSA sequence of mask image collection rotation (M) - C arm return (R) - contrast collection rotation (C), M-C rotational DSA that reduces the breath-holding time, as well as M-C-C rotational DSA enabling prolonged angiography from the arterial phase to the venous phase, are all possible. All of these sequences maintain the optimal timing for their respective purposes.
