Three-dimensional ultrasound biomicroscope for cylinder scanning

Abstract

The invention discloses a three-dimensional ultrasound biomicroscope for cylinder scanning. In the three-dimensional ultrasound biomicroscope, a motor 1, a coupling sheet 1, a photoelectric encoder 1 and a motor fixing sleeve are connected sequentially; one end of a motor 2 passes through an aperture on the base of the motor fixing sleeve and is fixedly connected with a coupling sheet 2; a supporting frame is fixed on the base of the motor fixing sleeve; a photoelectric encoder 2 is arranged between the base of the motor fixing sleeve and the coupling sheet 2; both ends of a transmission bar are connected with an off-centre position of the coupling sheet 2 and a transmission frame respectively; a guide rail is in a linear type and passes through a slot of the transmission frame, and both ends of the guide rail are fixed on the supporting frame; a sliding block is arranged below the guide rail and is fixed on the transmission frame; one end of a probe is connected with the transmission frame, and the other end of the probe is provided with a sensor; the sensor is connected with a control line board; the photoelectric encoder 1 and the photoelectric encoder 2 are connected with the control line board; and the control line board is connected with a programming controller. The three-dimensional ultrasound biomicroscope has a simple structure, a controllable scanning range and high scanning efficiency and is convenient to operate and simple in data processing.

Description

[technical field] [0001] The invention relates to the field of medical instruments, in particular to a three-dimensional ultrasonic biological microscope for realizing cylindrical scanning. [Background technique] [0002] Ultrasound Biomicroscope (abbreviation: UBM, English full name: Ultrasound Biomicroscope) is a new type of ophthalmic B-ultrasound imaging detection equipment developed in the early 1990s. UBM uses programmable logic devices to control electronic circuits to excite high-frequency ultrasonic sensors to emit high-frequency ultrasonic waves as a signal source, receive ultrasonic echo signals and perform electronic signal processing to obtain digital images related to inspection tissues, combined with computer image processing technology to provide people with It is similar to the effect of low-power optical microscope and the two-dimensional images of the front of the eye in different sections. UBM has the characteristics of high resolution, real-time, quanti...

Problems solved by technology

However, the sector scanning device has the disadvantages of narrow scanning range at a constant speed, high geometric distortion of the image, and a small clear range of the image. The measurement distance is always changing, the data processing is complicated, and the accuracy is low, which brings many troubles to clinicians.
