Appl. No.:

17/883775

Inventors:

- Eindhoven, NL

International Classification:

G01S 7/52
G01S 15/89

Abstract:

Front-end circuitry for an ultrasound system comprises a beamformer FPGA integrated circuit, transmit ICs with both pulse transmitters and linear waveform transmitters and T/R switches, transmit control and receiver ICs, and analog-to-digital converter (ADC) ICs. Only the transmit ICs require high voltages, and the transmit/receive switches are integrated in the transmit ICs, isolating the receiver ICs from high voltages. The transmitters can be trimmed to adjust the pulse rise and fall rates, enabling the transmission of pulses with low harmonic frequency content and thus better harmonic images.

International Classification:

G01S 7/52
A61B 8/00
A61B 6/00

Abstract:

Ultrasound imaging systems including transducer probes having wireless tags, and associated systems and methods, are described herein. For example, the wireless tags can store supplemental data about the transducer probes, and the ultrasound system can include a base unit configured to wirelessly communicate with nearby ones of the wireless tags to receive the supplemental data. The base unit can be further configured to display the transducer probes that are nearby. In some embodiments, the operator can filter or sort the displayed nearby transducer probes based on the supplemental data to identify a particular one of the nearby transducer devices that has one or more desired attributes.

Abstract:

Front-end circuitry for an ultrasound system is described which comprises a beamformer FPGA integrated circuit, transmit ICs with both pulse transmitters and linear waveform transmitters, transmit control and receiver ICs, and analog-to-digital converter (ADC) ICs. Waveform data for both the linear and pulser transmitters is stored in the transmit control and receiver ICs, saving pins on the FPGA, which is the conventional source of this data. The ADCs couple digital echo data to the FPGA for beamforming over serial bus lines, saving additional FPGA pins over a conventional parallel data arrangement. The inclusion of both pulser and linear waveform transmit capabilities in the transmit ICs enables the use of both types of transmitters in the formation of a multi-mode image, such as use of the pulsers for Doppler beams and linear transmitters for B mode beams in the formation of a colorflow image.
