title: An analytic derivation for the transient temperature rise during an ultrasound pulse focused on bone.
abstract: An analytic derivation is given for the maximum transient temperature rise due to millisecond ultrasound (US) pulses focused on bone. The temperature rise is found to have, within a small correction factor, a square-root dependence on the pulse duration and is independent of the focal diameter. The equation developed is essentially the same as that found in a previous paper that obtained the formula by numerical methods and subsequent curve fitting.
