Novel optically designed fluorescent camera and imaging method thereof

Abstract

The invention discloses a novel optically designed fluorescent camera. The novel optically designed fluorescent camera comprises a fluorescent camera and an image processing host, wherein the fluorescent camera comprises a color CMOS photosensitive chip, a black-and-white CMOS photosensitive chip and a beam splitter prism; the beam splitter prism is used for projecting incident light onto the color CMOS photosensitive chip and the black-and-white CMOS photosensitive chip respectively; and the image processing host is used for processing images on the color CMOS photosensitive chip and the black-and-white CMOS photosensitive chip. The invention also discloses a corresponding imaging method. Through adoption of the novel optically designed fluorescent camera, superposition of double CMOS images can be more accurate. The double CMOS images are imaged by the same camera, so that the surgical accuracy is increased in comparison to an existing double-camera fluorescent detector.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fluorescent camera with a novel optical design, and also relates to an imaging method for the fluorescent camera with a novel optical design. Background technique [0002] Medical imaging technology has greatly improved the accuracy of doctors' diagnosis of the cause and location of lesions, disease development stages, late recovery, and treatment, such as X-ray computed tomography (CT), positron emission tomography (PET), single Photon Emission Computed Tomography (SPECT), Spectral Imaging (FI) and Magnetic Resonance Imaging (MRI). However, compared with the medical imaging technology in the diagnostic stage, the imaging diagnostic technology in surgery, especially the imaging technology for judging tumor tissue, directly affects the success or failure of resection surgery and the postoperative rehabilitation effect of patients. However, so far, when surgeons check th...

AI Technical Summary

Problems solved by technology

However, so far, when surgeons check the surgical field of view, in most cases, they can only rely on the superficial phenomena observed by the naked eye to perform operations.

This reality makes it impossible to completely remove tumor tissue in up to 25% of cases during resection of tumor tissue; this situation further leads to a local recurrence rate of cancer cells as high as 28%

In addition, although the existing technical means such as CT and intraoperative ultrasound assessment can roughly determine and judge the extent of tumor tissue, 6% to 20% of tumor tissue metastasis cannot be detected, especially if it is very small (<5) metastases

Therefore, accurately judging the location of tumor tissue that needs to be removed, avoiding damage to the structure of normal tissue, and finding small metastatic lesions pose new challenges for clinical surgical techniques.
