摘要： A portable electronic device (e.g., smart phone or tablet computer) is provided for generating and displaying images (e.g., 2-dimensional or 3-dimensional images) of an imaging target such as a human body. The portable electronic device may include imaging elements configured to receive radiation signals transmitted through and/or reflected by the imaging target, an imaging interface, and one or more processors. The portable electronic device may display what appears to be a window into the imaging target (e.g., a human body), and/or an exploded view (e.g., 3-dimensional, upwardly projected image) of the target. The generated image may be a real-time continuous image of the internal features of the target (e.g., a human body) that is updated to track movements of the target (e.g., breathing patterns) and the relative position of the portable electronic device as the portable electronic device moves relative to a surface of the target.

摘要： Programmable ultrasound probes and methods of operation are described. The ultrasound probe may include memory storing parameter data and may also include a parameter loader which loads the parameter data into programmable circuitry of the ultrasound probe. In some instances, the ultrasound probe may include circuitry grouped into modules which may be repeatable and which may be coupled together to allow data to be exchanged between the modules.

摘要： Circuitry for ultrasound devices is described. A multi-level pulser is described, which can support time-domain and spatial apodization. The multi-level pulser may be controlled through a software-defined waveform generator. In response to the execution of a computer code, the waveform generator may access master segments from a memory, and generate a stream of packets directed to pulsing circuits. The stream of packets may be serialized. A plurality of decoding circuits may modulate the streams of packets to obtain spatial apodization.

摘要： To implement a single-chip ultrasonic imaging solution, on-chip signal processing may be employed in the receive signal path to reduce data bandwidth and an output data module may be used to move data for all received channels off-chip as a digital data stream. The digitization of received signals on-chip allows advanced digital signal processing to be performed on-chip, and thus permits the full integration of an entire ultrasonic imaging system on a single semiconductor substrate. The on-chip digitization of received signals also enables the on-chip integration of ultrasound processing and/or pre-processing to reduce the burden on off-chip computing. Data compression architectures are disclosed to facilitate the transfer of data off-chip as a digital data stream in accordance with the bandwidth requirements of standard commercially-available output interfaces.
