Estimation of the heart respiratory motion with applications for cone beam computed tomography imaging a simulation study.

Estimation of the heart respiratory motion with applications for cone beam computed tomography imaging a simulation study.

Computed tomography (CT) reconstruction methods assume imaging of static objects; object movement during projection data acquisition causes tomogram artifacts. The continuously moving heart, therefore, represents a complicated imaging case. The associated problems due to the heart beating can be ove...
