Edelmen's SPI Exam Review Guaranteed Success What is the relationship between frequency and wavelength in ultrasound? ️️Frequency and wavelength are inversely related; as frequency increases, wavelength decreases, enhancing resolution but reducing penetration depth. How does acoustic impedance affect ultrasound imaging? ️️Acoustic impedance is the resistance to sound wave transmission; differences in impedance between tissues cause reflections that form the ultrasound imag...

ARDMS SPI STUDY GUIDE ALREADY VERIFIED A+ How does harmonic imaging improve image quality? ️️Harmonic imaging reduces artifacts by using higher harmonic frequencies, which produce clearer, more detailed images than fundamental frequencies. What is the primary cause of side lobe artifacts? ️️Side lobe artifacts result from unwanted sound beams emitted at angles outside the main beam, potentially causing misleading echoes on the image. How does adjusting dynamic range affect ...
