ABSTRACT:
A method for increasing dynamic range of ultrasound imaging signals uses a barrel shifter. The barrel shifter shifts large bit two's complement input data into a standard size bit two's complement output. The method, then, comprises the steps of reducing a large data bus to a smaller data bus, and dynamically changing the amount of reduction. The bus reduction is achieved using a barrel shifter. Since time gain compensation (TGC), used to compensate for diminishing echo strength, increases with the depth of the signal, the amount of shift is directly related to the TGC value.
