BACKGROUND A detailed contrast bolus propagation model is essential for optimizing bolus-chasing Computed Tomography Angiography (CTA). Bolus characteristics were studied using bolus-timing datasets from Magnetic Resonance Angiography (MRA) for adaptive controller design and validation. METHODS MRA bolus-timing datasets of the aorta in thirty patients… (More)
In this paper, an adaptive scheme is proposed for a next generation CT scanner. The purpose of the control is to estimate the contract bolus position so its variations can be compensated by moving the patient table. The convergence result has been achieved and the experimental results are very promising.
