Problems solved by technology

The number of cancer cells left after surgical resection is an indicator to measure the success of surgical resection: the number of cancer cells left and the degree of complete removal greatly affect the later development of the disease. If there are too many cancer cells after surgery If the cells remain on the organ, it may directly reduce the effect of subsequent chemoth

Embodiment Construction

[0021] Most of the current fluorescence imaging systems are usually designed to have two or three cameras work at the same time in order to achieve the ability to simultaneously collect fluorescently labeled images of the lesion area, and divide the work to complete the task of real-time collection of different spectral images, and then the different spectral images Synthetic drug-targeted surgical images.

[0022] Existing fluorescent imaging systems with two or three cameras are bulky, cannot be miniaturized, and have poor mobility. Moreover, two or three cameras work at the same time, and the positions cannot be accurately overlapped, making image synthesis difficult and error-prone.

[0023] What needs to be pointed out is that the fluorescence imaging system with two or three cameras working at the same time must use visible illumination light photography for the whole lesion area, if the fluorescence imaging system in the visible light band is used for some tissues (such ...

Abstract

The invention provides a co-localization surgical navigation system and a camera lens. The navigation system comprises a first light source, a second light source and an image acquisition unit, wherein the first light source is used for providing visible light; the second light source is used for providing infrared light; centers of the visible light provided by the first light source and the infrared light provided by the second light source are overlapped; the image acquisition unit comprises a first image sensor and a second image sensor; the first image sensor is used for imaging based on the visible light provided by the first light source; the second image sensor is used for imaging based on fluorescent light excited by the infrared light provided by the second light source, wherein the first image sensor and the second image sensor share an optical path. The co-localization surgical navigation system and the camera lens, provided by the embodiment of the invention, have the advantages of small size, high precision and small interference, and can provide accurate positions of tumors.

Description

technical field [0001] The invention relates to the technical field of molecular imaging, in particular to a co-location surgical navigation system and a camera head. Background technique [0002] The most effective methods of cancer treatment are surgical resection and chemotherapy. The number of cancer cells left after surgical resection is an indicator to measure the success of surgical resection: the number of cancer cells left and the degree of complete removal greatly affect the later development of the disease. If there are too many cancer cells after surgery Cells left on the organ may directly reduce the effect of subsequent chemotherapy and the patient's chances of survival. [0003] For small-sized cancer tissue or tumor border, it is difficult for doctors to make accurate judgments from the naked eye and touch experience. Moreover, in the patient's lesion area, cancer tissue intersects with normal tissues such as blood vessels and nerves, which cannot be distin...
