WebAt our institution, we have implemented gated computed tomography (CT) acquisition with an active breathing control system (ABC), and 4-dimensional (4D) CT using a skin-based marker and retrospective respiration phase-based image sorting. During gated simulation, 3D CT images were acquired corresponding to end-inhalation and end-exhalation. WebThe images are acquired using the prospective method described in Section 19.4. The position and width of the segment of the respiratory cycle to be used, called the gate, are determined by observing the amount of motion and restricting it to below a specified limit during the gate, typically 5 mm. ...
