摘要： A system (102) includes an ultrasound probe (104). The ultrasound probe includes a probe head (202), a handle (208), and an elongate shaft (226) disposed between and coupling the probe head and the handle. The probe head houses a transducer array (114). The elongate shaft includes a first portion (232) coupled to the probe head and a second portion (234) coupled to the handle. The second portion includes a first end region (238) coupled to the handle. The second portion further includes a second end region (236) extending above the handle and coupled to the first portion such that a line of site from behind the probe to the probe head is visually unobstructed by the handle.

摘要： An ultrasound imaging system includes a transducer array (102) with a plurality of transducer elements (106) configured to transmit an ultrasound signal, receive echo signals produced in response to the ultrasound signal interacting with stationary structure and flowing structure, and generate electrical signals indicative of the echo signals. The system further includes a beamformer (112) configured to process the electrical signals and generate sequences, in time, of beamformed data. The system further includes a filter (118) configured to process the beamformed data, and remove or replace a set of frequency components based on a threshold, producing corrected beamformed data. The system further includes a flow processor (120) configured to estimate a velocity of flowing structure from the corrected beamformed data. The system further includes a rendering engine (224) configured to display the flow velocity estimate on a display (124).

摘要： A method is disclosed for determining a flow acceleration directly from beamformed ultrasound data, i.e. independent of velocity estimates. The method includes extracting data from two different times and a same position, or two different positions and a same time, from the beamformed ultrasound data, and producing cross- correlation data to directly estimate the flow acceleration. The flow acceleration estimate may be processed to derive information for analyzing ventricular performance, studying hemodynamics or estimating pressure gradients in the circulatory system. An apparatus includes a beamformer (112) configured to process electrical signals indicative of received echoes produced in response to an interaction of a transmitted ultrasound signal with tissue and generate RF data, and an acceleration flow processor (114) configured to directly process the RF data and generate a flow acceleration therefrom.
