Q-factor


 * Reference for term: Musculoskeletal Ultrasound - Holsbeeck Van, M. et al.
 * Comment: Q-factor refers to two characteristics of the transducer; the ring down time and the purity of the sound or bandwidth. A high Q-factor produces a pure sound but has a high ring down time, a low Q-factor produces an ultrasound beam containing a relatively wide variety of frequencies but has a short ring down time.
