This Technical Specification defines terms and specifies methods for quantifying the imaging performance of real-time, ultrasound B-mode scanners. The types of transducers used (see sections 7.6 and 10.7 of [1]) with these scanners include
  1. a) phased array,
  2. b) linear arrays,
  3. c) convex arrays,
  4. d) mechanical sector scanners,
  5. e) 3-D probes operating in 2-D imaging mode (see Annex K),
  6. f) 3-D probes operating in 3-D imaging mode for a limited number of sets of reconstructed 2-D images (see Annex K).
The test methodology is applicable for transducers operating in the 2 MHz to 15 MHz frequency range.
