Fig. lJ8z Schematic ilJustration of the uJtrasonography of a fluid filled veside. A = obIique wave impact b = peipendic-uiar wave impact c = tangential wave impact. D = hyper-ecboic distal wafl, E = relative echo enhancement, S = shad-ow artifacts.
Fig. 1.9: Ultrasonogram of an estrous follicle in a marę analo-gous to the schematic representation shown in Fig 1.8. C = tangential wave entiy. D = hyperechoic distal wali with specular reflection, E = relative echo enhancement, S = shad-ow artifacts.
