### TTT.2.5 Case #5: One Rotation, One 2D Instance, Multiple Reconstructions, One X-Ray 3D Instance

This application case is related to a rotational acquisition of several cardiac cycles with related ECG signal information.

#### TTT.2.5.1 User Scenario

The image acquisition system performs one 2D rotational acquisition of the heart in a cardiac procedure. The gantry is continuously rotating at a constant speed. The ECG is recorded during the rotation, and the cardiac trigger delay time is known for each frame of the rotational acquisition allowing it to be assigned to a given cardiac phase.

Several 3D volumes are reconstructed, one for each cardiac phase.
