An Image Interpolation Approach for Acquisition Time Reduction in Navigator-Based 4D MRI

Involuntary motion of anatomical structures due to factors such as breathing, peristalsis and heart beat is an important concern in image-guided therapy applications, such as planning and guiding radiotherapy (Bert and Durante, 2011) and high intensity focused ultrasound therapy  (Arnold et al., 2011). For instance, if such motion is not taken into account in radiotherapy, it may lead to dose distribution degradation (Lambert et al., 2005), reducing the efficacy of the treatment and irradiating healthy tissue.
