Embodiment Construction

[0027] combine Figure 1 to Figure 9 The principle of the ultrasonic imaging system of the present invention is explained. Such as figure 1 The ultrasonic imaging system of the present invention shown has five main parts: a transducer 3, a transmit beamformer 1 connected thereto, a scanning motor controller connected to the transducer 3 and transmit beamformer 1, and a transmit beamformer The receiving beam processor 4 connected with the device 1 and the electronic computer 5 connected with the receiving beam processor 4. Among them, the transducer 3 is a high-frequency ultrasonic (ultrasonic signal frequency is 15MHZ-80MHZ) transducer, under the excitation of multiple high-voltage pulse signals (excitation signals) with different delays generated by the transmitting beamformer 1, the transducer 3 Generate ultrasonic waves. Under the control of the scanning motor controller 2, the annular array transducer 3 can perform sectoral scanning, horizontal scanning and fixed scanni...

Abstract

The invention discloses an ultrasonic imaging system which comprises a sending beam generator (1), an annular array type transducer (3), a scanning motor controller (2), a receiving beam processor (4) and an electronic computer (5), wherein the sending beam generator (1) is used for producing different delayed excitation signals; the annular array type transducer (3) is electrically connected with the sending beam generator (1) and used for sending and receiving ultrasonic signals; the scanning motor controller (2) is electronically connected with the annular array type transducer (3) and the sending beam generator (1) and used for controlling working manners of the annular array type transducer (3); the receiving beam processor (4) is electronically connected with the sending beam generator (1) and used for processing echo signals; and the electronic computer (5) is electronically connected with the receiving beam processor (4) and used for displaying and storing an ultrasound image. The ultrasonic imaging system has the benefits that the cost is low, and the imaging performance is good.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic imaging, in particular to an ultrasonic imaging system and an imaging method. Background technique [0002] Medical ultrasound imaging technology is a medical imaging technology based on ultrasound. It has good penetration depth and imaging performance for non-invasive detection, and has been widely used in various medical applications. Ultrasound frequencies in traditional medical ultrasound imaging equipment range from 2MHz to 15MHz. High-frequency ultrasonic imaging technology is a high-precision imaging method derived from traditional ultrasonic imaging technology. It uses 15MHz to 80MHz ultrasonic waves for imaging, and can obtain imaging accuracy on the order of tens of microns. High-frequency ultrasound imaging technology has been gradually used in clinical applications such as ophthalmology imaging, dermatology imaging and intravascular imaging. In the preclinical experiment...
