Ultrasonics. Pulse-echo scanners. Low-echo sphere phantoms and method for performance testing of gray-scale medical ultrasound scanners applicable to a broad range of transducer types1 Scope 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 a) phased array, b) linear arrays, c) convex arrays, d) mechanical sector scanners, e) 3 D probes operating in 2 D imaging mode (see Annex K), f) 3 D probes operating in 3 D imaging mode for a limited
