Problems solved by technology

One problem is that a wire with thousands of wires from the system beamformer to the transducer elements would make the cable very thick and impractical
Another problem is that a lot of power is wasted in driving thousands of components with transmitted signals, causing too much heat in the probe

Embodiment Construction

[0013] First reference figure 1 , Illustrates in block diagram form a probe microwave beam shaper ASIC10 suitable for 2D imaging probes according to the principles of the present invention. Considering only the receiving function of the microwave beamformer, the ASIC 10 has sixty-four inputs coupled to sixty-four elements of the 1D transducer array. The microwave beamformer ASIC controllably delays the signals from the sixty-four transducer elements before combining them into groups of sixteen input channels. The product is the output of four partial beamforming signals. In this example, each output is a combination of signals from sixteen transducer elements. The microwave beam shaper ASIC10 thus reduces the 64 input channels to four output channels, which provides a convenient standard microwave beam shaper structure for various 2D imaging probes.

[0014] figure 2 Illustrates the use of this standard structure with a systematic microbeamformer in accordance with the princip...

Abstract

A 2D ultrasound imaging system has a number of different probes for different clinical applications. Each 2D imaging probe has a one dimensional array transducer and one or more microbeamformers coupled to the individual elements of the array. Preferably the microbeamformers are the same, and serve as a standard component of the system. The microbeamformers combine signals from the elements of their transducers and every probe has from four to sixteen outputs of partially beamformed signals. The mainframe system has a beamformer with four to sixteen channels, which completes the beamformation process for each probe.

Description

Technical field [0001] The present invention relates to an ultrasonic medical diagnostic imaging system that performs two-dimensional (2D) imaging, and in particular, to a 2D ultrasonic diagnostic system with two beamformer stages. Background technique [0002] Medical diagnostic imaging systems with multi-element solid-state probes use beamformers to control and focus the beam. Traditionally, the beamformer is in the electronic compartment of the host system and is coupled to the transducer array of the probe through the probe cable. The channel of each beamformer is coupled to one of the elements in the array transducer of the probe. During transmission, the beamformer channel provides a properly timed transmission signal for the element that causes the transmission beam to be controlled in the desired direction and focused at the desired depth. During the reception of the generated echo signal, the process is reversed. Each channel appropriately delays the echo signal from ...
