摘要: A method and apparatus for compensating the effects of variable attenuation in a body being scanned by an ultrasound pulse echo scanner which compensation signal is derived on basis that strength received at any time instant after generation influenced both back scatter. The comprises array transducers (15) generate from echo, means (16) applying time-dependent gain to produce function signal, temporary storage (17) integrator (18) operable sum values each commencement point, (19) combining integrated with stored original form quotient, (20) displaying thus generated.
