Document Summary
Ultrasound physics and instrumentation, 5e chapter 4: level 1. Answer: pulse duration (pd: the range resolution equals the spatial pulse length divided by 2. Answer: 6 microseconds: the wavelength multiplied by the number of cycles in a pulse defines the: Ultrasound physics and instrumentation, 5e chapter 4: level 2. Quiz answers: the lack of range specificity, referred to as ________________ ________________ is the greatest limitation of continuous wave operation. Answer: range ambiguity: in the book, illustrations showing sound bouncing reflecting from objects was used to demonstrate the limits of cw and the advantage of pw. Answer: (0. 05 mm): it is more difficult to differentiate structures which are closer together. Note that 0. 05 mm is equivalent to 50 m, which is closer together than 500 m: in the book, an example based on a person"s work week was given for the duty factor.
