Patent number: 11553896Abstract: A handheld ultrasound device comprises a plurality of components configured to provide decreased size, weight, complexity and power consumption. The handheld ultrasound device may comprise an ultrasound transducer and an analog to digital (“A/D”) converter coupled to the ultrasound transducer. A processor comprising a beamformer can be coupled to the A/D converter and configured to selectively store a plurality of signals from the A/D converter in a memory of the processor. The beamformer can be configured to implement and compress a flag table in place of a delay table. These improvements can decrease the amount of memory used to generate ultrasound images, which can decrease the size weight and power consumption of the handheld ultrasound device.Type: GrantFiled: November 4, 2020Date of Patent: January 17, 2023Assignee: VAVE HEALTH, INC.Inventors: Jung Woo Choe, Amin Nikoozadeh

Patent number: 11531096Abstract: A handheld ultrasound device may comprise components configured to provide decreased size, weight, complexity, and power consumption. The handheld ultrasound device may comprise a beamformer configured to implement and compress a flag table in place of a delay table. These improvements can decrease the amount of memory used to generate ultrasound images, which can decrease the size, weight, and power consumption of the handheld ultrasound device. Ultrasound image data on a handheld imaging probe can be compressed on the handheld imaging probe prior to transmission from the probe in order to decrease the amount of data transmitted from the probe. The compressed data may comprise compressed pixels to maintain spatial image resolution. The compression circuitry may comprise an amount of memory related to a dynamic range of the compressed data that is independent of the dynamic range of the input data, which can decrease memory, power consumption, and latencies.Type: GrantFiled: March 23, 2018Date of Patent: December 20, 2022Assignee: VAVE HEALTH, INC.Inventors: Amin Nikoozadeh, Jung Woo Choe, Stefan Craciun

The compressed data may comprise compressed pixels to maintain spatial image resolution. The compression circuitry may comprise an amount of memory related to a dynamic range of the compressed data that is independent of the dynamic range of the input data, which can decrease memory, power consumption, and latencies. The compression circuitry can be configured to pipeline data such as image data in accordance with clock cycles, such that throughput of outputting data words is increased.Type: GrantFiled: September 19, 2019Date of Patent: June 9, 2020Assignee: VAVE HEALTH, INC.Inventors: Jung Woo Choe, Stefan Craciun, Amin Nikoozadeh
