The effectiveness of Intensity Modulated Radiation Therapy (IMRT) is compromised by involuntary motion (e.g. respiration, cardiac activity). Feasibility of processing ultrasound echo data to automatically estimate 3D liver motion for real-time IMRT guidance was previously demonstrated with an acquisition speed limit of 2 volumes per second, due to hardware restrictions of a mechanical linear array probe. Utilizing a 2D matrix array probe with parallel receive beamforming offered increased… CONTINUE READING
