Problems solved by technology

[0005] In view of this, the present invention provides a hand-held probe for three-way cooperative scanning optical coherence tomography, which is small and portable. The problem of insufficient imaging depth caused by absorption and absorption, scanning in three directions of field of view makes up for the shortcoming of limited information in one-way scanning, and has anti-shake function, which greatly improves the clarity of imaging

Embodiment Construction

[0041] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0042] The present invention provides a three-way cooperative scanning optical coherence tomography handheld probe, which is designed based on Micro-Electro-Mechanical System technology (Micro-Electro-Mechanical System, referred to as MEMS), such as figure 1 As shown, the hand-held probe includes a hand-held probe barrel, an anti-shake stage 8 and an optical processing module. The optical processing module is arranged in the hand-held probe barrel.

[0043] The optical processing module can realize cooperative scanning of blood vessels 32 in three directions, such as image 3 As shown, the optical processing module includes MEMS oscillating mirror 14, coated mirror 17, stepped glass slide 15, double glued achromatic objective lens group 16, circular glass slide 18, reflector a19 and reflector b20; MEMS galvanometer 14 The diameter is 2.4mm; the coated ref...

Abstract

The invention provides a hand-held probe capable of three-way cooperative scanning and optical coherence tomography. The hand-held probe comprises a hand-held probe cylinder, an anti-shake carrying table and an optical processing module, wherein the optical processing module is disposed in the hand-held probe cylinder; and the front end of the hand-held probe cylinder is clamped with the anti-shake carrying table, so shaking is prevented. The probe provided by the invention is characterized in that the probe is small and portable; cooperative scanning in three directions can be achieved by the optical processing module; a function of one-direction scanning of a traditional hand-held probe is inherited; the problem in the insufficient imaging depth caused by internal scattering and absorption of blood vessels during one-directional scanning can be overcome; the scanning in the three view field directions remedies the deflect of information limit in the one-directional scanning; and the anti-shake function is provided, so imaging definition is increased greatly.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to a hand-held probe for three-way cooperative scanning optical coherence tomography. Background technique [0002] As a high-resolution and high-speed imaging technology, optical coherence tomography (OCT) can provide three-dimensional imaging for biological tissues that cannot be achieved by other imaging technologies. In terms of biomedical research and clinical application, this technology has been successfully used in the clinical operation navigation and result diagnosis process of vascular surgery, such as OCT technology is used in the intraoperative evaluation of vascular suture surgery, intravascular plaque removal surgery surgical navigation. OCT technology will play an increasingly significant role in the diagnosis, monitoring and treatment of vascular diseases in the future. [0003] Whether it is to monitor the status of blood vessels (normal and dis...
