Harmonics correct answers multiples of the transducer frequency, created in tissues , twice the frequency. Work b/c fundamental beam undergoes distortion. Improve spatial resolution (inversion). Non linear behavior creates harmonics. - HARMONICS = higher frequencies than the indecent frequency (overtones) - micro bubbles generate stronger harmonic signals than tissue - RESULT: narrower beams, fewer side lobes, better contrast, better spatial resolution Head form correct answers Look at mach...

I. OBJECTIVE To study the behaviour of oscillations (Simple Harmonic Motion) in situation where there is resistive force of fluid investigated by study of exponential amplitude decay in the fluid as compared to relatively undamped environment of air. II. HYPOTHESIS During Simple Harmonic Motion (SHM) in damped fluid environment amplitude of oscillation decreases exponentially. And the rate of amplitude decay depends on viscosity of fluid medium. III. THEORY Simple Harmonic Motion (SHM), is...

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 2025 Guaranteed A+ What is the effect of decreasing the transducer frequency on image quality? ️️Decreasing the transducer frequency improves penetration depth but reduces image resolution, making it better for imaging deeper structures. How does beam width impact lateral resolution? ️️Narrower beam width improves lateral resolution by providing clearer detail of structures located side by side. What causes acoustic shadowing, and how does it appear on an ultrasound ima...

RCRD 3005 Audio Eng Final Review Questions with 100% Verified Correct Answers What is the Equal Loudness Principle? - Correct Answer The ear is much more sensitive to mid-range frequencies than low and high frequencies at low volumes. As volume increases, the curve of our hearing flattens out so we hear all frequencies equally (around 85db). However, our ears become more sensitive to highs and lows once volume increases past this point. What is amplitude? - Correct Answer The height/vertical...
