Embodiment Construction

[0027] reference below Figure 1 to Figure 4 The invention is further described by way of non-exhaustive exemplary embodiments.

[0028] exist figure 1 In , a system (100) for measuring arterial parameters is shown. The system (100) includes a signal unit (101) having a plurality of transducer elements arranged in a grid configuration. These transducer elements operate individually or collectively to provide unprocessed radiofrequency ultrasound signals appropriate for the artery of interest to be measured. Measurements according to the invention include the use of radio frequency ultrasound signals in raw and demodulated form. The radio frequency demodulation unit (102) demodulates unprocessed radio frequency ultrasonic signals. The detection unit (103) is arranged to detect the presence of blood flow in the artery of interest using Doppler spectral data obtained from the demodulated radio frequency ultrasound signal. When the presence of blood flow is detected, the conc...

Abstract

The present invention relates to a system for measuring the arterial parameters. The system of the invention comprises a signal unit for providing radio frequency (RF) ultrasound signal and demodulated RF ultrasound signal and of the data relating thereto from the signal acquired therefrom; a detection unit for detecting the presence of blood flow in an artery; an identification unit for identifying the said artery; a processing unit for processing the said data and for providing the distension waveform of the said artery; and an estimating unit for estimating at least one of a plurality of localized arterial parameters of the said artery. The invention also relate to a method for measuring the arterial parameters by the system of the invention. The invention has the advantage of measuring localized blood pressure continuously and also other localized arterial parameters such as Peak Systolic Velocity, Pulse Wave Value and arterial compliance measures, in a non-imaging, non-invasive and cuff-less manner.

Description

technical field [0001] The present invention relates to measuring arterial parameters, and more particularly to a system and method for measuring arterial parameters using radio frequency ultrasound. Background technique [0002] Generally, blood pressure measurement is considered an ideal biomarker to assess a patient's health status. For this purpose, blood pressure is measured before surgery or during routine health checks and even when the patient is under medical observation. Conventionally, blood pressure is measured on the brachial artery to determine systolic and diastolic measurements. These measurements are generally considered standard for all arteries. [0003] Typically, blood pressure is measured with a sphygmomanometer. The blood pressure measured here is the aortic blood pressure from which, with some variation, the blood pressure over the brachial artery is estimated. This method primarily utilizes a cuff that is placed around the upper arm and inflated ...
