Each option must be used once, and they should be matched to the best corresponding answer.

As the technology advances, equipment changes and advances are occurring in diagnostic imaging. For each of the traditional pieces of equipment listed, match it with its new and upcoming replacement equipment.       1.   Image intensifier is being replaced with 2.  Vidicon camera is being replaced with 3.  Cathode ray tube – CRT is being replaced with 4.  Cine and spot film recording is being replaced with 5.  Continuous on x-ray tube is being replaced with     A.  Grid controlled fluoroscopy- GCR B.  Flat Panel Monitor C.  Flat panel Image receptor _ FPIR D. Picture archival and communication – PACS E.  Charged coupling device – CCD    

MR sequence parameters are generally selected on the basis of __________.

You measure a sound at 400 mPa. How many dB is this? Round your answer to the nearest whole number. (Do not include units, just the number.)

If the speed of sound stays the same and the wavelength increases, what happens to the frequency?

A 440 Hz sinewave and a 450 Hz sinewave are added together. In the resulting SAM wave, what are the carrier frequency (fc) and the modulation frequency (fm)? Carrier frequency: [a] Hz Modulation frequency: [b] Hz

Answer the following based on this sinusoid: What is the period? [a] seconds What is the frequency? [b] Hz What is the peak-to-peak amplitude [c] mPa What is the starting phase? [d] degrees
