CT imaging depending on an intrinsic respiratory surrogate of a patient

An adaption device, comprising:

• an acquisition unit configured to acquire Computed Tomography (CT) raw data from an examination volume of a patient;
• a reconstruction unit configured to reconstruct 3D-CT images of stacks of the examination volume at different z-positions based on the CT raw data;
• a segmentation unit configured to perform an automatic segmentation based on the 3D-CT images, at least a portion of the examination volume being segmented by the automatic segmentation;
• a surrogate determination unit configured to determine a respiratory movement of at least the portion of the examination volume as an intrinsic respiratory surrogate of the patient;
• and
• an adaption unit configured to adapt a CT imaging process based on the intrinsic respiratory surrogate, the adaption including performing a first operation in response to detecting a breath of the patient has not been held according to a first command, and the detecting being based on the intrinsic respiratory surrogate.

An adaption device, comprising:

• processing circuitry configured to cause the adaption device to
• reconstruct, at different z-positions, 3D-CT images of stacks of an examination volume of a patient based on CT raw data from the examination volume,
• perform an automatic segmentation based on the 3D-CT images, at least a portion of the examination volume being segmented by the automatic segmentation;
• determine, as an intrinsic respiratory surrogate of the patient, a respiratory movement of at least the portion of the examination volume;
• and
• adapt a CT imaging process based on the intrinsic respiratory surrogate of the patient, the adaption including performing a first operation in response to detecting a breath of the patient has not been held according to a first command, and the detecting being based on the intrinsic respiratory surrogate.
