Simulation-based analysis of the effect of hot spot size, image SNR and undersampling scheme on compressed sensing reconstruction of MR temperature images during HIFU treatment
Abstract:Compressed sensing MRI can accelerate MRI temperature monitoring of tissues undergoing the high-intensity focused ultrasound (HIFU) treatment. This paper investigates the relationship between the accuracy of the MRI temperature maps reconstructed using reference image-based compressed sensing and some parameters such as the HIFU hot spot size, the image signal-to-noise ratio (SNR) and the k-space undersampling scheme by a simulation approach. Results indicate that a big HIFU hot spot size almost always helps t… Show more
