3D image reconstruction

3D image reconstruction is a hot spot in ultrasound image processing and has become a development trend of ultrasound imaging. The first 3Dultrasound imaging commercial device uses mechanical scanning probes that oscillate in perpendicular directions to collect data of interest within 3 seconds, and perform image reconstruction to generate sagittal, coronal, and cross-sectional images. These planes can be adjusted within the range of ultrasound information capacity, and multiple continuous images can be seen.

There are many problems to be solved in 3Dultrasound imaging, including data acquisition methods, real-time image reconstruction, and clinical reference value. At present, four data collection methods have emerged: parallel scanning, rotating scanning, sector scanning, and free-hand Scanning. The most eye-catching 3Dultrasound imaging is real-time 3Dimaging. The key to real-time 3Dimaging is to use parallel data processing and shorten data acquisition time. Acoustic pulses are emited in several directions at the same time, and simultaneously acquires and processes multiple sound beam information of the scan line, which obviously increases the complexity of the ultrasound imaging system.

Wide-band probe

The wide-band probe send out continuous ultrasonic pulse signals, so that the ultrasonic signals in a certain frequency range can be transmitted and received without gaps.

Ultra-wideband probe

On the basis of the wide-band probe, the ultrasonic signal range that the probe receives and transmits is further expanded. The signal of the ultra-wideband probe is completely carried out at the moment of reception, and is fully digitally coded and amplified to ensure that the signal is not distorted and expand the dynamic range of the signal.
