Abstract

The invention relates to a handheld MEMS optical scanning imaging device. The optical scanning imaging device comprises a handle (1) and a probe (2) arranged at one end of the handle (1), the other end of the handle (1) is provided with a photoelectric interface (3), a channel is formed in the handle (1), an optical fiber (13) for connecting the probe (2) with the photoelectric interface (3) is arranged in the channel, the probe (2) comprises a probe body (4), a probe head (5) and an MEMS driver (6) connecting the probe body (4) with the probe head (5), a sample arm (20) connected with an optical fiber (13) is arranged in the probe head (5), and the probe body (4) is connected with the handle (1). The device is provided with the handle and the bendable probe which accord with the human body structural design, so the device can be used for acquiring real video images of sample tissues and two-dimensional and three-dimensional optical tomographic images of a target area in real time.

Description

technical field [0001] The invention relates to the field of medical imaging equipment, in particular to a hand-held MEMS optical scanning imaging device. Background technique [0002] Optical coherence tomography (OCT) is a high-resolution optical imaging technique. It is based on the principle of low coherent light interference, and realizes the exploration of the microstructure of biological tissues by detecting weak light signals reflected from different depth layers in biological tissues. A two-dimensional or three-dimensional image of the sample is obtained by deflecting the direction of the incident light. OCT technology has the advantages of non-invasive, high resolution, high speed and high sensitivity, and can realize non-invasive detection of human body and living organisms. [0003] Oral cancer is a general term for malignant tumors that occur in the oral cavity and is one of the ten most common tumor diseases. The most common and highest incidence of oral can...
