Embodiment 1

[0035] figure 1 A schematic diagram of a multimodal colposcopy system provided by an embodiment of the present invention, such as figure 1 As shown, the system mainly includes: image module, light source module, control module and structure module;

[0036] The image module includes: a photosensitive device 6, a lens 5, a filter 4 and a computer 8; the photosensitive device 6 is connected to the computer 8, the lens 5 is fixedly installed on the photosensitive device 6, and the optical filter 4 In front of lens 5.

[0037] Exemplarily, the photosensitive device can be a CCD industrial camera, which can collect 12-bit black-and-white monochrome images, and the efficiency of its CCD spectral response curve in the 470-600nm band is >80%, which is better for multi-spectral images and fluorescent images. efficiency. The CCD industrial camera is connected with the data acquisition card on the computer 8 through a 1394A fire wire to realize image acquisition and data transmission....

Embodiment 2

[0045] An embodiment of the present invention provides a method for acquiring multimodal images, which is implemented based on the multimodal colposcopy system provided in the foregoing embodiments, and the method mainly includes:

[0046] Adjust the photosensitive device and the lens so that the cervical tissue to be observed conforms to the field of view;

[0047] Then use the computer to control the control module to adjust the light source module, and then perform multi-spectral imaging, autofluorescence imaging and RGB color imaging in sequence to obtain multi-modal images;

[0048] Wherein, when performing multispectral imaging, a standard reflection block is placed on the surface of the observed cervical tissue for pre-exposure, the standard reflection block is removed, and then multispectral imaging is performed on the observed cervical tissue; The filter switching device adjusts the position of the filter so that the filter does not block the imaging optical path;

Abstract

The invention discloses a multimodal colposcope system and a method for acquiring multimodal images. According to the multimodal colposcope system and the method for acquiring multimodal images, opening and closing of all channels of a light source and the intensity of the light source are controlled independently through the ultra-bright LED light source and an imaging module which are selected through the special arrangement design and the wavelength, and several sorts of different medical imaging modalities are fused organically. Substance compositions can be effectively classified by multispectral imaging, normal tissue and lesion tissue can be distinguished according to fluorescence intensity by cervix uteri autofluorescence imaging, a doctor can be guided to judge the development degree of a nidus from the aspect of forms, colors and the like by conventional RGB color imaging, and therefore a more comprehensive, accurate and quantitative diagnosis basis can be provided for the doctor.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multimodal colposcope system and a method for acquiring multimodal images. Background technique [0002] Globally, the incidence of cervical cancer ranks second among female malignancies, second only to breast cancer. In developing countries, due to imperfect cervical screening, the incidence of cervical cancer is six times that of developed countries, and the death rate ranks first among female cancers. Traditional cervical screening methods mainly include Pap smear and colposcopy. [0003] However, the former has a high rate of misdiagnosis, pain for the examinee, and long inspection cycle, while the latter can realize RGB color imaging of cervical tissue, but it can only be judged intuitively from the color and shape of the tissue surface, and cannot distinguish benign epithelial tissue changes. and malignant tumors. Contents of the invention [0004] The purp...
