Description
Dechen Kong and co-authors offer a radiation-free way to model the skull for focused ultrasound treatment in a paper published in 2025. Ultrasound can treat tremor and Alzheimer's disease through the skull, but planning usually needs a CT scan, which brings radiation and alignment errors. Their method builds the sound model from a special MRI instead.
A porosity index drawn from those MR images replaces the CT-based measure of bone sponginess. Simulations on a standard platform compared focus quality between the two approaches across five measures. Peak intensity differed by under five percent, and the focus shapes matched closely. No measure differed significantly. The authors conclude the MRI route is a feasible stand-in for CT in treatment planning.
