Edge shadowing - Study guides, Class notes & Summaries

Artifact -Answer An echo feature present or absent in a sonographic image that does not correspond to the presence or absence of a real structure. Eg. enhancement or shadowing. Attenuation -Answer The reduction of intensity (and amplitude) of a sound wave as it travels through a material. Attenuation is due to absorption, reflection, and scattering. Complex -Answer A structure in the body that contains both cystic and solid components. Echogenic -Answer A structure or medium that p...

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...
