Abstract: An apparatus and method for estimating one or more hemodynamic parameters such as cardiac output or stroke volume. Embodiments are based on the concept of incorporating information about vascular tone into hemodynamic parameter estimation to improve accuracy. More particularly, embodiments use a measurement of a time duration for a blood pulse to travel from the heart along a certain length of an arterial path as a proxy measure for vascular tone, and incorporate this into hemodynamic parameter estimation. Embodiments are also based on incorporating vascular tone proxy measurements for multiple different arterial paths to take account of vascular tone variations between different portions of the circulatory system.

Abstract: Systems and methods for applying therapeutic ultrasound to the brain while using ultrasound to compensate for the attenuation and dephasing of ultrasound by each individual's head. The compensation delivers into the target deterministic ultrasound intensity. The compensation is based on relative ultrasound through-transmit measurements, which are performed using a set of ultrasonic emitters over one side of the head and a set of receivers on the other side. The measurements are performed with the head absent and present. Based on the difference between these measurements, the set of ultrasound waves is adjusted to compensate for attenuations and dephasing caused by the ultrasound wave passing into the head through the skull and scalp. The adjusted set of ultrasound waves provides intended, deterministic ultrasound intensity at the target location.
