SPI Practice Test Verified A How does adjusting the depth setting impact frame rate? ️️Increasing depth reduces frame rate because the system requires more time to receive echoes from deeper structures. What is the main advantage of tissue harmonic imaging? ️️Tissue harmonic imaging improves image clarity by using higher-frequency harmonics, reducing artifacts from superficial layers. Explain the purpose of axial and lateral resolution. ️️Axial resolution distinguishe...

SPI Practice (ARDMS A & B), spi ardms test A and B, ARDMS PRACTICE SPI (B) Exam Questions With 100% Correct Answers. What is the distance to the interface if the round trip time for a sound wave is 39 microseconds? - answer3cm which signals are eliminated by the wall filter in a spectral Doppler display? - answerlow frequency, low amplitude at minimum, what is required when documenting a pathology discovered during an examination? - answertwo images demonstrating the same pathology from...

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...

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 ...
