AUTOMATED MAGNETIC RESONANCE IMAGE SEGMENTATION FOR ULTRASOUND THERMAL THERAPY CONTROL

摘要

A system and method for acquiring magnetic resonance (MR) images, with an MR system, of tissue proximal to a target treatment region in a patient, the tissue including a non-spatially uniform subcutaneous fat layer; in a computer comprising a hardware-based processor, automatically determining a thickness of the subcutaneous fat layer using a trained neural network, the neural network trained using manually-segmented MR images from previous patients; in the computer, automatically adjusting a treatment parameter based on the thickness of the subcutaneous fat layer; and delivering thermal therapy to the target treatment region with a high-intensity focused ultrasound system based on the adjusted treatment parameter.
