Embodiment Construction

[0050] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0051] Such as figure 1 As shown, an ultrasonic probe includes a telescopic lens barrel 1, a pressure sensor 2, a controller, a probe 3 and a stepper motor 4 that drives the probe 3 to rotate, and the stepper motor 4 is arranged on the telescopic lens barrel 1 ((similar to the telescopic lens barrel of a single-lens reflex camera), the probe 3 is fixedly connected to the output shaft of the stepper motor 4, the pressure sensor 2 is arranged at the front end of the telescopic lens barrel 1, and the controller controls The expansion and contraction of the telescopic lens barrel 1 and the operation of the stepping motor 4. The pressure sensor 3 is used to check the pressure between the ultrasonic probe and the eye, becau...

Abstract

The invention relates to an ultrasonic probe, which comprises a telescopic lens cone, a pressure sensor, a controller, a probe and a stepping motor for driving the probe to rotate. A three-dimensional reconstruction method of an eye two-dimensional ultrasound image by applying the ultrasonic probe comprises the following steps: carrying out equal-angle rotary scanning through the ultrasonic probe to obtain eye two-dimensional ultrasound image data; converting the eye two-dimensional ultrasound image data obtained by the equal-angle rotary scanning into discrete scalar data on a spherical coordinate system grid; converting the generated scalar data on the spherical coordinate system grid into data on a rectangular grid of a Cartesian coordinate system; and carrying out trilinear interpolation to non-integer points on the rectangular grid of the Cartesian coordinate system to obtain the intensity values of the non-integer points to form one group of three-dimensional data set of the intensity values, and finishing the three-dimensional reconstruction of the eye two-dimensional ultrasound image. Compared with the prior art, the invention has the advantages of clear reconstruction image, high sense of reality, high imaging speed and the like and can be applied to clinic systems.

Description

technical field [0001] The invention relates to a three-dimensional reconstruction method and system for an ultrasonic probe and a two-dimensional ultrasonic image of the eye. Background technique [0002] B-ultrasound has been widely used in clinical diagnosis in hospitals, and B-ultrasound can also be used for eye disease diagnosis in ophthalmology. The echo of the B-ultrasound is represented by a light spot, and each echo forms a light spot on the display screen. The brightness of the light spot indicates the echo intensity. The stronger the echo, the brighter the light spot. Connecting the light spots becomes a two-dimensional image. When the refractive medium is opaque, B-mode ultrasound detection is one of the methods to understand the situation in the eye, and it can check white pupil syndrome, unclear refractive medium, retinal and choroidal detachment, fundus protuberance, eyeball atrophy, unexplained Vision loss and high intraocular pressure, suspected intraocular...
