SYSTEMS AND METHODS FOR REDUCING THERMAL SKULL-INDUCED ABERRATIONS DURING TRANSCRANIAL ULTRASOUND THERAPEUTIC PROCEDURES
Various example embodiments of the present disclosure provide systems and methods for the dynamic correction and reduction of thermal variations in skull-induced aberrations during a focused ultrasound therapy procedure. Unlike conventional approaches involving static corrections for skull-induced aberrations, various example embodiments of the present disclosure employ ultrasound detection and a skull thickness estimate from volumetric image data to intermittently and dynamically determine corrections for skull-induced aberrations, such that aberration correction reduction is updated intraoperatively and maintained despite local thermally-induced changes in the speed of sound of the local skull region due to intraoperative intracranial heating. Furthermore, in some example embodiments, a measure dependent on the speed of sound with the skull is intraoperatively determined and compared to a previously determined value of the measure to determine a change in the skull temperature, based on a pre-determined relationship between changes in the measure and changes in skull temperature.
Transcranial doppler probe
According to various embodiments, there is provided a headset mountable on a head, the headset including a probe for emitting energy into the head. The headset further includes a support structure coupled to the probe. The support structure includes translation actuators for translating the probe along two axes generally parallel to a surface of the head.
Method to Quantify the Hemodynamic and Vascular Properties in Vivo from Arterial Waveform Measurements
Disclosed herein are in vivo non-invasive methods and devices for the measurement of the hemodynamic parameters, such as such as blood pressure, stroke volume, cardiac output, performance of the aortic and mistral heart valves, arterial blood velocity profile, blood viscosity and the blood flow induced arterial wall shear stress, hypertensive/hypotensive and vasodilation/vasocontraction state and aging status of a subject, and the mechanical anelastic in vivo properties of the arterial blood vessels. An exemplary method requires obtaining the peripheral pulse volume waveform (PVW), the peripheral pulse pressure waveform (PPW), and the peripheral pulse velocity waveform (PUW) from the same artery; calculating the time phase shift between the PPW and PVW, and the plot of pulse pressure versus pulse volume; and determining the blood pressures and power law components of the anelastic model from the waveforms PPW and PVW, the cardiac output and heart valves performances from the waveforms PPW and PUW, and the anelastic in vivo properties of the descending, thoracic and abdominal aorta. The disclosed methods and devices can be used to diagnose and treat cardiovascular disease in a subject in need thereof.
