Answer #1

Ultrasound probes can resolve structural details with sizes approximately equal to the wavelength of the ultrasound waves themselves.

The smallest feature observable in a human tissue with ultrasounds at 15 MHz and a wavespeed of 1540 m/s is approximately equal to the wavelength

here, f = frequency and c = wave speed.

So,

So the size of the smallest feature observable in human tissue when examined with 15-MHz ultrasound is 0.1026 mm (Approx).

A diagnostic sonogram produces a picture of internal organs by passing ultrasound through the tissue. In one application, it is used to find the size, location, and shape of the prostate in preparation for surgery or other treatment. The speed of sound in the prostate is 1560 m/s, and a diagnostic sonogram uses ultrasound of frequency 1.85 MHz. The density of the prostate is 1060 kg/m^3 . What is the wavelength λ of the sonogram ultrasound? λ=________________m What is the...

a Doppler ultrasound machine can measure blood flow speeds, for instance, in a patient’s artery. The probe is illustrated below. First, here are two questions about the Doppler effect: When a listener is moving away a stationary source that emits a sound wave of frequency f, the listener will hear a sound of   ["smaller frequency", "the same frequency", "greater frequency"]           When a source that emits a sound wave of frequency f moves away a stationary listener, the listener...
