SPI PRACTICE QUESTIONS ALL ANSWERS CORRECT What is the purpose of axial resolution in ultrasound? ️️Axial resolution allows for the distinction between two structures along the direction of the sound beam, determined by pulse length and frequency. How does acoustic enhancement appear on an ultrasound image? ️️Acoustic enhancement appears as increased brightness behind fluid-filled structures, as fluids cause minimal attenuation of sound waves. What is the primary factor tha...
