Ultrasonic Image Generation Method Using Concave Shape Array

Abstract

The present invention relates to an ultrasonic image generation method using a concave array, which is characterized in that the concave array composed of more than one ultrasonic transducer is placed on the cornea, and the ultrasonic image is generated by using the ultrasonic waves sent and received by the concave array, and then displayed The generated ultrasonic image, in which the focal point of the concave shape array is on the vitreous body, by making the concave shape of the concave shape array consistent with the shape of the cornea, the refraction of ultrasonic waves is minimized, the loss of ultrasonic energy is minimized, and finally the Ultrasound imaging of the posterior eye.

Description

technical field [0001] The present invention relates to an ultrasonic image generation method using a concave shape array, and more particularly relates to minimizing the refraction of ultrasonic waves and minimizing the loss of ultrasonic energy by making the concave shape of the concave shape array consistent with the shape of the cornea, and finally can be used for postoperative imaging. Ultrasonic image generation method using concave shape array for ultrasonic imaging of the eye. Background technique [0002] High frequency ultrasound (high frequency ultrasound) is an ultrasound having an operation frequency 10 times or more of the conventional ultrasound operation frequency range of 2-10 MHz (above 20-100 MHz). [0003] Ophthalmology imaging is one of the fields where high-frequency (HF) ultrasound imaging technology is applied. High-frequency ultrasound in the range of 35MHz to 100MHz is used for the zonular fiber that often appears in the ciliary body, tumor and cys...

Problems solved by technology

Therefore, the existing ultrasonic transducer arrays with linear or convex shapes cannot effectively transmit ultrasonic waves to the posterior segment of the eyeball or receive ultrasonic waves emitted from the posterior segment of the eye

[0009] That is, in the case of using a linear array of transducer elements or a convex array of transducer elements to generate an eye retinal image, due to the circular shape of the eye, high transmitted ultrasonic refraction occurs on the cornea and lens, resulting in This creates the problem of not being able to get a high resolution image in the desired area
