An ultrasound imaging system is configured to interface with a dual frequency ultrasound transducer having one or more low frequency ultrasound arrays and one or more high frequency ultrasound arrays. The imaging system produces driving pulses for both the high frequency ultrasound array and the low frequency ultrasound imaging array. Analog echo signals are processed to produce a low frequency ultrasound image and a high frequency ultrasound image that are simultaneously displayed. Tissue shown in the high frequency ultrasound image is a portion of the tissue shown in the low frequency ultrasound image.

Ultrasound system with high frequency detail

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.

Ultrasound transducer with data compression

A system for acquiring an ultrasound signal comprises a signal processing unit adapted for acquiring a received ultrasound signal from an ultrasound transducer having a plurality of elements. The system is adapted to receive ultrasound signals having a frequency of at least 20 megahertz (MHz) with a transducer having a field of view of at least 5.0 millimeters (mm) at a frame rate of at least 20 frames per second (fps). The signal processing can further produce an ultrasound image from the acquired ultrasound signal. The transducer can be a linear array transducer, a phased array transducer, a two-dimensional (2-D) array transducer, or a curved array transducer.
