An oct imaging system for in vivo multi-parameter measurement with integrated optical fiber sensing

Abstract

The invention relates to the technical field of optical fiber sensing medical devices, in particular to an OCT imaging system for integrated optical fiber sensing in-vivo multi-parameter measurement.The OCT imaging system includes a light source module, a first coupler, a first annular device, an interference module, a special-shaped optical fiber microprobe, a photoelectric detector and a balance detector. Two output ports of the first coupler are connected with an input end of the interference module and a port A of the first annular device respectively; the special-shaped optical fiber microprobe is connected with an interference arm of the interference module and a port B of the first annular device through sector-shaped optical fiber bundles separately; the balance detector is connected with the interference module and a data processing module separately, and the photoelectric detector is connected with a port C of the first annular device and the data processing module separately. The OCT imaging system is reasonable in structure, the OCT probe is integrated with an FBG temperature sensing optical grating and an F-P pressure sensing unit, and the temperature, pressure and other parameters of body tissue are measured at the same time. Precise observation of the shape of the tissue and high-resolution large-scale imaging are achieved, and a significant meaning is achievedon in-vivo tissue diagnoses and the like.

Description

technical field [0001] The invention relates to the technical field of optical fiber sensing medical devices, in particular to an OCT imaging system for in-body multi-parameter measurement with integrated optical fiber sensing. Background technique [0002] Biomedical photonics has become a multidisciplinary and rapidly developing field, and it is also an important part of research in frontier fields of important disciplines such as life sciences and medical imaging. OCT is an important imaging technique in biomedical photonics research because it can visualize tissue structures at high speed and high resolution. Advances in the preparation of flexible fiber optic probes have promoted the development of in vivo OCT imaging techniques. In 1996, Tearney et al. used an early catheter to obtain OCT images of human coronary arteries. In order to reduce the influence of involuntary human motion, Makita et al. reported non-invasive Doppler OCT on the human retina. In 2013, W.J.C...

But this can only realize the imaging of diseased tissues, and the current imaging probes, temperature, pressure and other probes are large in size and cannot enter tissues such as micro blood vessels, which makes it extremely difficult to image micro tissues and measure multiple parameters at the same time
