Problems solved by technology

However, in the prior art, there is no technology that combines spectral imaging and endoscopic technology for accurate diagnosis, and the existing imaging spectrometer needs to scan in the spatial dimension or spectral dimension to obtain the data cube of the atlas information, and the existing Imaging spectrometers struggle to scan in tight spaces of endoscopes

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the drawings.

[0018] An endoscopic spectral imaging system of the present invention, such as figure 1 As shown, it includes: an endoscopic module 100, a spatial transformation and transmission module, a spectral imaging module 400, and a data acquisition and analysis module 600.

[0019] The endoscope module 100 includes an objective lens group 101, an image transmission group 102, and an illumination assembly 103. The objective lens group 101 is arranged at the front end of the endoscope module 100. In actual operation, the objective lens group 101 is arranged at In the patient's body near the affected area tissue 700, the image transmission group 102 is arranged behind the objective lens group 101, and the illumination assembly 103 is connected to the endoscope module 100 and may be arranged at the front end of the endoscope module 100. The objective lens The group 101 is used to collect the scatte...

Abstract

The invention discloses an endoscopic spectral image system. The spectroscopic imaging system provides high resolution imaging in the form of lens imaging, the large field of view imaging is carried out by using the objective lens set composed of multiple lenses, the optical signal is transmitted out through the image transmission group, and the first optical fiber bundle rearranges the two-dimensional spatially arranged optical fiber bundle, outputs the two-dimensional spatially arranged optical fiber bundle to a slit through the first output end, and sequentially transmits the two-dimensional spatially arranged optical fiber bundle to a detector through a collimator, a convex grating and a first focusing mirror, and finally the data acquisition and analysis module acquires information. The spectral imaging system adopts soft and hard structure and combines spectral imaging technology with endoscopic technology to realize high spatial and high spectral resolution instantaneous imagingin medicine. The instantaneous spectral detection in vivo is realized by using spatially transformed optical fiber bundle without any moving parts to obtain 3D dynamic information in vivo and the high spatial resolution imaging is realized by using lens imaging.

Description

Technical field [0001] The invention relates to the field of medical diagnostic equipment, and in particular to an endoscopic spectral imaging system. Background technique [0002] Endoscope is a commonly used medical device. With the help of endoscopists, doctors can observe the pathological changes of internal organs and provide precise treatment plans. Clinically, it can be used for gastrointestinal diseases, pancreatic biliary diseases, abdominal and respiratory diseases, urinary and cranial nerve diseases. Endoscopes are generally divided into rigid scopes and soft scopes. The rigid endoscope uses a lens group for imaging, while the soft endoscope uses an optical fiber for imaging. Endoscopes mainly use spatial imaging to obtain detailed images of tissues and lesion areas, and judge diseases based on doctors' experience. Spectral imaging is a technology that combines maps and spectrums. It can not only obtain the spatial information of the target but also the spectral lin...
