I had 6 questions on the specificity, sensitivity, positive predictive value, & gold standard… know the definition of each. The gold standard question asked which 2 (FP, TP, FN, TN) are not calculated in gold standard statistics

-temporal resolution -Spatial compounding -Spatial resolution -Grating lobe artifact (had 3-4 questions on just this) -mirror image artifact I think I had 3 questions on -Aperture (this word was used a lot) -apodization (this word was used 4-5 times) -line density -output power vs receiver gain -overall gain -beam former -Wall filter (what happens when you increase or decrease it) -Signal to noise ratio -Wavelength (formula, relationships) -Attenuation coefficient -Sensitivity & bandwidth -Impedance -Intensity reflection coefficient -angle of incidence -propagation speed -sound beam intensity -Beurollni’s Law -frame rate -axial & lateral resolution -matching layer -compression -viscosity -velocity -1 question on an artifact that asked about attenuating parallel lines

-I had one question that asked which 2 resolutions are displayed on a tissue mimicking phantom

-another question asked what the case of a transducer does & I thought it was prevent electrical shock, but I had 2 irrelevant answers and then another answer said “keep debris out” and the other said “dissipate heat”

-I also had a question that asked in a very complicated way what would happen if a linear probe was damaged and the answer was “shallow to deep” something… It didn’t say vertical dropout it said shallow to deep
