For rotational studies, C-Arms do remarkably well for serial acquisitions obtained from a static perspective. For rotational studies, a different set of design parameters is required to achieve optimal results. For example, the imaging components of the VA100 are fully enclosed, allowing significantly higher rates of rotation to be safely achieved. This eliminates the need for long contract injections, and eliminated the possibility of collisions. Because the VA100 is built around an extremely rigid framework, vibration and motion between the X-Ray source and the image receptor during the rotational sweep are eliminated as well. Subtraction images remain in registration during the entire acquisition. The full circle arc of rotation available on the VA100 will not compromise the visualization of complex anatomy, while the tilting gantry provides excellent anatomic coverage. As a result of these design features, contrast introduction techniques for rotational studies with the VA100 are very similar to those used with the C-Arm, reducing the need for guesswork. A variety of scan times is also available to accommodate a variety of flow rates. Setup and rehearsals are accomplished in seconds, because the system is designed for rotational imaging from the ground up. Single button controls allow the rotational sweep to be observed fluoroscopically to insure appropriate alignment. When used in combination with the SX-VA-30 C-Arm, transitions from one system to the other can be accomplished smoothly because of the integrated control design.
