Claim 13:
14. A method, comprising:
transmitting, by a first element of a transducer, a first ultrasound beam toward a blood vessel;
detecting, by the first element, a reflection of the first ultrasound beam from a first portion of a wall of the blood vessel;
determining, by a processor, a change in a slant range at the first portion of the wall of the blood vessel by analyzing the reflection of the first ultrasound beam;
transmitting, by a second element of the transducer, a second ultrasound beam toward the blood vessel, the second ultrasound beam being nonparallel to the first ultrasound beam;
detecting, by the second element, a reflection of the second ultrasound beam from a second portion of the wall of the blood vessel;
determining, by the processor, a change in a slant range at the second portion of the wall of the blood vessel by analyzing the reflection of the second ultrasound beam;
determining, by the processor, a pulse wave velocity of the blood vessel by determining a time period between the determination of the change in the slant range at the first portion of the wall of the blood vessel and the determination of the change in the slant range at the second portion of the wall of the blood vessel; and determining, by the processor, a blood pressure of the blood vessel by multiplying the pulse wave velocity with a velocity of blood flowing through the blood vessel.
