Lentis three-dimensional imaging ultrasonography and appropriative ultrasonic probe array

Abstract

The invention discloses a human eye lens 3D imaging ultrasonic scanning method and a special ultrasonic probe array. A data processing unit controls scanning to the ultrasonic probe array formed by a plurality of ultrasonic probes regularly arranged on a probe bracket, scans transmitting signal one by one and processes the echoed signals on the other ultrasonic probes in the ultrasonic scanning array to acquire a lens 3D image. The lens 3D imaging ultrasonic scanning method can not only acquire a 3D solid image and has the biggest advantage that as no anesthetization is needed on the eyeballs of a person to be detected when the ultrasonic probe array ultrasonically scans the human eyes, the invention can utilize a principle that the lens of the two eyes are carrying out the same regulation simultaneously when the human eyes watch an object normally to directly observe the diopter adjustment changes of the curves in front of and behind the lens and observe the function of how to adjust the lens with ciliary muscle in real time with full range; thereby providing an effective technical means for researching the adjusting mechanism of eyes.

Description

technical field [0001] The invention relates to a human eye lens three-dimensional imaging ultrasonic scanning method and a special ultrasonic probe array. Background technique [0002] The human eye is the most important sensory organ in the human body. It is very perfect, delicate and inconceivable. It is the inevitable product of the long-term evolution of life to an advanced form. The structure of the human eye is equivalent to a video camera or camera. The front is composed of the cornea, lens, anterior chamber, posterior chamber, and vitreous body, which have the function of a lens, and focus the light emitted by the object onto the rear retina for detecting light. More than 85% of the external information that people sense is obtained through the eyes. The lens is one of the important refractive media in the eyeball. It is in the shape of a biconvex lens, with a radius of curvature of about 10mm in the front and about 6mm in the back, and is elastic. The diameter ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the existence of existing measurement methods for ophthalmic lens research, although the lens can be measured and observed, but it cannot be observed in real time, in a full range, directly, and it cannot draw a three-dimensional image of the lens in the adjustment process. It can rely on the limited data for image reconstruction to provide a lens three-dimensional imaging ultrasound scanning method, which realizes the non-invasive and painless multi-directional real-time observation of the diopter adjustment changes of the front and rear surfaces of the lens, and the observation of ciliary How muscles regulate the function of the lens
