WebAn ultrasound (also known as ultrasonography, sonography, or sonogram) helps doctors look for tumors in certain areas of the body that don’t show up well on x-rays. Doctors often use this procedure to guide a needle during a biopsy. Ultrasounds are usually quick and most don’t require special preparation. WebFor preclinical imaging applications, shear waves are generally generated by a lower frequency 20 MHz radiation pulse and a 40 MHz probe used to measure the shear wave propagation within the liver tissue. FIGURE 15. Figure 15. (A) B-mode image of right lobe of normal mouse liver. Imaged using 40 MHz probe.
