Embodiment Construction

[0033] Hereinafter, the present invention will be described more fully with reference to the accompanying drawings that show embodiments of the invention. It should be understood, however, that the invention may be embodied in many different forms and therefore should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the description of the invention will be thorough and complete.

[0034] A typical ultrasound imaging system such as figure 1 As shown, it includes an ultrasonic transducer / probe 11, an array element selection module 12, a transmitter group 13, a receiver group 14, a beam combiner 15, a wave detection and signal processing module 16, a digital scan converter DSC module 17 and a display 18. The beamformer 15 consists of a set of channel processing units. Each channel processing unit corresponds to one or more transducer units. This correspondence depends on the number of transducer units and the numbe...

Abstract

The invention relates to digital beam synthesis in the process of digital echo-signal reception in ultrasonic imaging, and provides a time division multiplexing beam synthesis device and method, and a data processing method of beam synthesis. The device comprises an echo-signal data write / reading unit, a multi-beam processing unit, a port data summing unit, and further comprises a parameter distribution and synchronization unit which is used to distribute and synchronously send relative received parameter of each beam in each port to the echo-signal data write / reading unit and the multi-beam processing unit through a parameter loading bus.

Description

technical field [0001] The invention relates to ultrasonic imaging in an ultrasonic diagnosis system, in particular to digital beam forming in the process of receiving digital echo signals. Background technique [0002] In an ultrasound imaging system, an ultrasound transducer is composed of a group of transducer units. The ultrasonic imaging process needs to transmit ultrasonic waves and receive ultrasonic echoes, and each transducer unit of the ultrasonic imaging system is connected to a transmitter and a receiver. For cost considerations, generally multiple receivers share one echo processing unit. [0003] During imaging, each transmitter transmits ultrasound pulses with a set time delay through the associated transducer unit. When each transducer unit in the ultrasonic transducer emits ultrasonic pulses with a set delay, the energy of the emitted ultrasonic pulses can be focused at a set position and direction. These transmitted ultrasound pulses are reflected by the...
