Diagnostic ultrasound exposure: medical, educational and commercial.
Rather than spending scarce research funds on the construction of ultrasonic tissue phantoms (as suggested in the AAPM statement), the author recommends the use of videotapes in place of live models for commercial sales demonstrations. While agreeing with AAPM safety standards, the author feels that an unduly conservative approach could impede the development of newer instrumentation.
