Problems solved by technology

However, due to the complexity of the system due to the use of dual image sensors, images acquired by different image sensors need to be accurately registered, and the cost is high
To this end, Sony Corporation of Japan proposed a single image sensor system, patented imaging device, imaging system, surgical navigation system and imaging method (CN 201110188577.6). Acquire white light and fluorescence images, but need to turn off the surgical environment light during the procedure

Embodiment Construction

[0020] like figure 1 As shown, the present invention is a multi-mode fluorescence imaging surgical navigation system. The visible light source 1 and the excitation light source 2 respectively emit visible illumination light and fluorescence excitation light to irradiate the target tissue 11. The imaging optical module 3 is imaged onto the image acquisition module 8, the fixed filter module 4 blocks the fluorescence excitation band light from entering the image acquisition module, and the dynamic filter module 5 is composed of a rotating motor 6 and a filter wheel 7, controlled by the control module 9 The red, green, blue and fluorescent radiation bands are filtered out sequentially, and the control module 9 synchronously controls the image acquisition module 8 to acquire image information of corresponding bands, and the acquired image information is transmitted to the display module for display after image processing.

[0021] The visible light illumination module is a xenon l...

Abstract

The invention discloses a fluorescence imaging surgical navigation system, which comprises an illumination light source, an excitation light source, an imaging optical module, a fixed filter module, adynamic filter module, an image acquisition module, a control module and a display module. The invention adopts a single camera combined with a sequential filter system, which breaks through the shortcoming that the conventional single camera can only obtain fluorescence images, and at the same time, compared with the traditional dual camera imaging system, the structure is simpler, compact, andthe cost is lower, and the use scenes of different fluorescence probes and a plurality of fluorescence probes are easy to be expanded.

Description

technical field [0001] The invention relates to the field of fluorescence imaging medical equipment, in particular to a fluorescence imaging operation navigation system. Background technique [0002] According to statistics from the United Nations, 1 out of every 8 deaths in the world currently dies of cancer. Improving the survival rate of cancer patients and controlling the incidence of cancer have become urgent medical problems. At present, the main methods of tumor treatment include chemotherapy, radiotherapy and surgical resection, among which surgical resection is the preferred method for the treatment of tumors, and this method is a treatment method that removes the primary tumor and metastatic lesions together. The positioning of malignant tumor tissue and the determination of surgical margins during clinical surgery are mainly based on preoperative imaging examinations, intraoperative doctor's naked eye observation and hand probing tissue results, and comprehensive...
