Trans-cranial focused ultrasound without hair shaving: feasibility study in an ex vivo cadaver model. Eames, M. D., Hananel, A., Snell, J. W, Kassell, N. F, & Aubry, J. Journal of Therapeutic Ultrasound, 1(1):24, December, 2014.
Paper doi abstract bibtex In preparing a patient for a trans-cranial magnetic resonance (MR)-guided focused ultrasound procedure, current practice is to shave the patient’s head on treatment day. Here we present an initial attempt to evaluate the feasibility of trans-cranial focused ultrasound in an unshaved, ex vivo human head model. A human skull filled with tissue-mimicking phantom and covered with a wig made of human hair was sonicated using 220- and 710-kHz head transducers to evaluate the feasibility of acoustic energy transfer. Heating at the focal point was measured by MR proton resonance shift thermometry. Results showed that the hair had a negligible effect on focal spot thermal rise at 220 kHz and a 17% drop in temperature elevation when using 710 kHz.
