Abstract
A transducer for an ultrasound imaging system includes an array of transducer elements and an analog-to-digital converter configured to convert analog signals produced by the transducer elements into corresponding digital samples that are encoded with a first number of bits. One or more memories are used to store digital samples associated with frames of ultrasound data. A processor or logic circuit in the transducer is configured to compress the digital ultrasound data by calculating differences between the samples and encoding the differences with a second number of bits that is less than the first number of bits. In addition, the logic circuit is configured to transmit a packet that includes the differences encoded with the second number of bits and an overflow portion that encodes the differences that are too large to be encoded with the second number of bits.
