Definitions
- the present invention relates to a method and a device for detecting, locating and characterizing differences in density, structure or chemical composition of a biological tissue.
- Various methods of detecting, or highlighting, tissue differences, of physiological or histological origin, pathological or not, have been proposed in the prior art, using autofluorescence of tissues containing endogenous chromophores or fluorescence caused by administered dyes or exogenous chromophores.
- Such a method has been used to direct observation of lesions c 'ariates on hard tissues such as tooth enamel, or soft tissue such as skin or the oral mucosa, or endoscopically on the thoracic or abdominal endocavitary mucous membranes.
- Various methods of detecting and characterizing tissue differences have also been proposed, in which tissues are illuminated by means of a mono-chromatic light of determined wavelength, so as to cause the latter to emit radiation by luminescence. at a different wavelength.
- the intensity of the light must also be high, which can cause parasitic fluorescence emissions which can deteriorate the signal / noise ratio and mask the detection of the relevant signal.
- the object of the present invention is to propose a method and a device making it possible to ensure the detection, the localization, and the characterization of differences in structure, or others, of a biological tissue, this device being of simple constitution, of a low cost, easy to implement, and able to eliminate the various artefacts related to the various hazards likely to act on the surface of the fabric and likely to disturb the measurement.
- the present invention thus relates to a method for detecting and locating the difference in density and / or structure and / or chemical composition of a biological tissue which is subjected to continuous light in a first strip of determined frequencies, capable of causing the latter to generate a phenomenon of fluorescence, autofluorescence, or luminescence in a second frequency band, characterized in that it comprises the steps consisting in: - carrying out an image capture of the biological tissue thus lit, by color video means provided with image sensors with a mosaic of pixels provided with complementary color filters, - for each point of the image thus obtained: a) collect information relating to the energy received by each pixel, so as to reconstruct the image of the biological tissue, b) amplify the signal corresponding to the energy received in the second frequency band so as to characterize, or show on the image obtained, said difference in biological tissue.
- the present invention also relates to a device for detecting and locating the difference in density and / or structure and / or chemical composition of a biological tissue, characterized in that it comprises: - means capable of illuminating continuously the biological tissue with a light located in a first determined frequency band, so as to cause it to generate a phenomenon of fluorescence in a second frequency band, - color video means provided with image sensors with a mosaic of pixels provided with complementary color filters, - input and calculation means capable, for each point of the image thus obtained, of collecting information relating to the energy received by each pixel, so as to reconstruct the image of biological tissue, means of amplification of the signal corresponding to the energy received in the second frequency band, so as to characterize, or make appear on the image obtained, said difference of the biological tissue.
- This device may also include means for processing the information collected in the second frequency band, so as to characterize the difference in structure obtained in a color other than that naturally corresponding to this second frequency zone.
- the present invention also relates to a method for detecting and locating the difference in density and / or structure and / or chemical composition of a biological tissue which is subjected to continuous illumination in a first frequency band determined, able to cause it to generate a phenomenon of fluorescence, autofluorescence, or luminescence in a second frequency band, characterized in that it comprises the steps consisting in: - carrying out an image capture of the tissue biological thus illuminated, by image capture means consisting of monochrome image sensors, namely a luminance sensor and at least one sensor provided with a filter of the color corresponding to that of the fluorescence emitted during detection of a desired difference, - for each point of the image thus obtained: a) collecting information relating to the energy received by each pixel, so as to reconstruct the i biological tissue mage, b) amplifying the
- the present invention also relates to a device for detecting and locating the difference in density and / or structure and / or chemical composition of a biological tissue, characterized in that it comprises: means capable of illuminating in continuously the biological tissue with a light located in a first frequency band determined so as to cause it to generate a phenomenon of fluorescence in a second frequency band, - image capture means consisting of image sensors monochrome, namely a luminance sensor and at least one sensor provided with a filter of the color corresponding to that of the fluorescence emitted when detecting a desired difference, - suitable means of input and calculation, for each point of the image thus obtained, to collect information relating to the energy received by each pixel so as to reconstruct the image of the biological tissue, - means of am plification of the signal corresponding to the energy received in the second frequency band so as to characterize, or show on the image obtained, said difference in biological tissue.
- the present invention is particularly advantageous in that, unlike the devices of the prior art, it does not use a monochromatic light source, which allows it on the one hand to use a greater part of the energy supplied by the light source and, on the other hand, by using a band of radiation located in the visible range, to provide an image of the tissues studied (in the dental field a image of the tooth or, in other areas, the image of a mucous membrane, the skin, an eye, etc.).
- the CCD sensors of the color video means will be provided, at the level of each of the pixels, with filters the color of which will preferably be that of the complementary colors, namely yellow, magenta, and cyan .
- FIG. 1 is a schematic view of a device for detecting location and characterization of the difference in structure of a following biological tissue
- FIG. 2 is a schematic view showing the ranges of wavelengths which are used in the case of a clinical application of the dental field according to the present invention.
- the device according to the invention which is shown in FIG. 1 consists of a xenon lamp 1 which is supplied by a current generator 3.
- the light which is non-monochromatic emitted by the lamp 1 is filtered at the lamp outlet by a filter 4 making it possible to conserve at the output a band of radiation extending from the ultraviolet to the near visible.
- These light radiations pass through a waveguide tube 5 and continuously illuminate biological tissue, here constituted by a tooth 7 of a patient.
- the waveguide tube 5 is crossed by a central and longitudinal channel of axis xx 'through which a color video camera 11 is able to film the tooth 7.
- the camera 11 is connected to means of signal processing 13 themselves connected to video display means
- the filter 4 is, in the present embodiment, able to let pass a band of wavelengths centered around 370 nm, part of this frequency band, as shown in FIG. 2, comprising a part A located in the visible range.
- the mineral constituent of the tooth namely the enamel of the tooth. ci
- the parts of the tooth enamel which have undergone a start of partial deterioration due to caries, emit fluorescence radiation in the 650 nm range, in other words at the level of the radiations. red.
- an image is recorded using the color video camera 11 which is the result of several spectral bands, namely: - an image of the tooth resulting from the illumination produced thereon by the visible part of the illumination spectrum, - an image of the tooth coming from the fluorescence of the enamel thereof generated by its illumination in the ultraviolet region produced by the illumination spectrum, - a fluorescence image (in the area of red is approximately 650 nm) emitted by the altered areas of the tooth enamel resulting from caries.
- the fluorescence signal generated in the red (around 650 nm) is amplified by the altered parts of the tooth.
- the pixels of the CCD sensors are preferably equipped with filters of complementary colors, namely yellow, magenta and cyan to which a green filter is added. It is understood under these conditions that a pixel provided for example with a yellow filter will allow red radiation and green radiation to pass if such a pixel receives light energy. As soon as this pixel receives energy luminous it will then be necessary to determine if it is a red radiation, in which case it will be necessary to amplify it, or on the contrary if it is a green radiation, in which case it will not be amplified.
- filters of complementary colors namely yellow, magenta and cyan to which a green filter is added.
- the present invention also makes it possible, in order to facilitate the detection of the altered area of the tooth, to eliminate from the display parasitic fluorescences of neighboring colors caused by other parameters such as in particular tartar, dental plaque, or amalgam results of previous treatments, or any other biological element useful for the diagnosis sought. It has thus been found experimentally that by adding to the illumination spectrum radiation located in a wavelength range of the order of 400 nm, the fluorescence spectrum produced is modified by shifting the fluorescence band from the parasitic fluorescences.
- the image capture means would then consist on the one hand of a first luminance sensor and on the other hand of a sensor provided with a filter of the color corresponding to that of the fluorescence emitted during the detection of the difference sought.
- this filter will have a color allowing 650 nm radiation to pass through and in the case of a search for dysplastic or carcinomatous tissue, it will have a color allowing 500 nm radiation to pass through.
- the device according to the invention will then only be able to detect anomalies of a single type. It would of course be possible to then provide other monochrome sensors fitted with other filters, each allowing access to an additional application.
- the camera 11 may be provided with means enabling it to operate either in fluorescence detection or in viewing the area observed in video image conventional.
- the objective will be provided with a filter corresponding to an attenuation of the light emitted.
- the handpiece of the camera will be provided with a switch allowing to use the dedicated filter when one is in fluorescence or to deactivate it for conventional video imaging. In fluorescence mode, it will also be possible to put a color filter in front of the lens to improve the contrast.
- the implementation of the present invention has been mainly described with regard to applications located mainly in the dental field, it can also be used for the detection and localization of tissue damage such as that of the mucosa bronchial whose autofluorescence in the green (around 500nm) decreases and that in the red increases around 600nm.
- sensors other than CCD could be used, and in particular CMOS sensors.
