Definitions
- the invention belongs to the field of medical ultrasonic diagnostic imaging, and in particular relates to a wide-beam transmitting method and a transmitting system for ultrasonic imaging.
- Ultrasound imaging has become one of the most widely used clinical diagnostic tools because of its non-invasive, real-time, convenient operation, low price and many other advantages.
- Commonly used functional modes of ultrasound imaging include two-dimensional black and white (B) mode, spectral Doppler mode (PW/CW), and color flow mode (CF/PDI).
- B mode relies on the amplitude of the ultrasonic echo signal for imaging, and obtains the two-dimensional structure and morphological information of the tissue.
- the basic principles of /CW and CF/PDI modes are the Doppler effect, which both rely on the phase of the ultrasound echo signal for imaging, and obtain blood flow information such as speed, direction, and energy.
- the core components of ultrasound imaging equipment include: probe, probe board, transmitter/receiver board, transmitter/receiver control board, beamformer, signal and image processing unit, and display.
- the basic workflow is: the probe emits a focused ultrasonic beam, and the probe is different
- the primitive receives the ultrasonic echo signal and enters each channel for amplification and filtering.
- the channel-level signal undergoes beam synthesis to obtain a radio frequency signal (RF signal).
- RF signal radio frequency signal
- the scanning process is repeated until a frame of radio frequency signal with a certain line density is obtained.
- the quadrature signal (IQ signal) is obtained through demodulation and filtering.
- the quadrature signal is processed to obtain an image, and the image is post-processed and finally displayed on the display.
- the bulletin number "CN101190133A” and the invention title “Wide beam transmission method and device in ultrasonic diagnostic system” disclose a technology for realizing wide beam transmission, which divides the transmission aperture of the ultrasound probe into N Sub-apertures, and the focal point is divided into N sub-focuss laterally.
- N sub-apertures and N sub-focuss establish a one-to-one correspondence.
- Each sub-aperture has M elements, all of which are focused on the sub-focus corresponding to the aperture, and the pulse is generated
- the N sub-apertures of the ultrasound probe are excited by the N sub-aperture to obtain a transversely stretched transmitting sound field.
- the transmitting sound fields of the N sub-apertures are respectively superimposed after focusing at their corresponding sub-focuses, and finally form a sound field that can cover all received linewidth beams; Both N and M are integers greater than 2.

- a transmitting aperture is divided into several sub-apertures, each sub-aperture focuses on a focal point at a different lateral position at the same depth, and the position of each focal point corresponds to one of the receiving lines.

Although it has stronger energy and better resolution at the focal depth, the energy becomes weaker and the resolution becomes worse outside the focal depth, which is shown in the image as the gray scale and resolution consistency of the near, middle and far fields. not good.

- This scheme sets the parameters of the focus arc, and based on the set parameters of the focus arc, calculates the emission delay of each element in the probe launch aperture to control each element to emit ultrasound.
- This scheme adopts circular arc focusing, which changes the calculation method of strong focusing transmission delay, so that the beam is no longer focused to a point to obtain a wide beam.
- the second solution of the prior art changes the emission focus into a focus arc, and its purpose is to evenly distribute the sound field energy of each emission to the focus arc, and increase the transmit beam width to ensure that the multiple receiving lines received in parallel have relatively uniform energy ;
- This technology has stronger energy and better resolution at the depth of the focused arc, but the energy becomes weaker and the resolution becomes worse outside the depth of the focused arc.
