| 内容記述 | A target tracking technique using relative displacements of gravity points of cross sectional images of blood vessels was proposed to guide the ultrasound focus in the liver which moves with respiration. Experiments with healthy volunteer livers demonstrated that the average error of the target position estimation was within 3mm. The error was less than 4mm even with a position prediction process for considering time delay between the time points of position estimation and transducer setup. These results suggested that the proposed technique was sufficient for guiding the focus and hence the imaging slab position and orientation for the "self-reference" thermometry. | |||||
