Q1: 10.12.2 (a) Rewrite the expression for the total free energy change for nucleation (Equation 10.3a) for the case of a cubic nucleus of edge length a (instead of a sphere of radius r). Now differentiate this expression with respect to a (per Equation 10.3b) and solve for both the critical cube edge length, a', and also $\Delta G^*$. (b) Is $\Delta G^*$ greater for a cube or a sphere? Why?

QUESTION 10 You are pulsing a 6 MHz ultrasound transducer. If 100% of the signal reflects back from a distance of 10 cm, compute the signal loss in dB of the signal as it arrives back at the transducer. (Since you are computing LOSS, the number in dB will be positive.) QUESTION 11 Given a 90 degree field-of-view, a line density of 1.111 lines/degree, and a scan depth of 7.69 cm, compute the resulting frame rate in frames/sec. QUESTION 12 Due to heat generation and scatter, the ultrasound sound signal loses intensity as it travels through the tissue. What is the mechanism employed by an ultrasound system to counteract this affect? Scan conversion Time gain control Logarithmic compression Envelope detection QUESTION 13 What signal processing technique is used to achieve the second step in the RF signal demodulation proess? Low pass filter High pass filter Discrete Fourier transform
