Abstract
An apparatus includes a high intensity focused ultrasound (HIFU) system and a magnetic resonance (MR) imaging system. A memory stores: instructions, pulse sequence commands for an acoustic radiation force imaging protocol, and first and second sonication commands. The pulse sequence commands specify acquisition of the MR data for first and second pulse sequence repetitions. The pulse sequence commands specify for each of the sequence repetitions a first and a second group of motion encoding gradients. Execution of the instructions causes a processor to: acquire first and second MR data by controlling the MR imaging system with the pulse sequence commands and by controlling the HIFU system with the first and second sonication commands, respectively; reconstruct first and second motion encoded images from the first and second MR data, respectively; and construct a displacement map from the difference of the first and second motion encoded images.
