Description
Technical Field
The invention belongs to the technical field of laser optical display, and particularly relates to a medical remote laser shooting display system.
Background
With the popularization of digital imaging, digital display and network technology, high-definition medical image technology and the like have rapidly developed.
The quality of pathological section images is the gold standard and gold data in medical diagnosis, and directly influences the judgment of doctors on the types of diseases and the disease conditions.
The quality of the surgical images, particularly minimally invasive surgical images, can affect the surgical accuracy of the surgeon.
At present, medical imaging illumination light sources (such as halogen lamps and LEDs) have too small color gamut and have too low light intensity in certain color development light bands, so that pathological sections or endoscope imaging is not clear. When the halogen lamp is used as an imaging light source of a pathological section or an endoscope, the intensity of the blue light wave band of the halogen lamp is low, so that the blue light noise of the digital image sensor of the blue light wave band is large when the halogen lamp is used for imaging, and the details of an image are not clear enough.
The super-high-definition medical imaging by using the multi-primary-color narrow-linewidth light source is an important direction for the development of the international medical imaging technology.
There are technical solutions to replace halogen lamps with white LEDs. However, when a white LED is used as the imaging illumination light source, color deviation may occur due to the fact that the white LED is a small color gamut, wide spectrum imaging illumination light, and the color gamut coverage/area of the LED image does not match the color gamut coverage/area of the display. Such color deviation also affects the image clarity of pathological sections.
To solve the above problems, chinese patent 202011479767.9 uses illumination light of a laser mixed with an LED to enhance the imaging sharpness of the endoscope to the lesion; the four-color laser illumination fluorescence microscope proposed in chinese patent 202010354407.X hopes to better illuminate biological tissues with illumination light of various wavelengths, so as to obtain images higher than the conventional illumination; similarly, chinese patent 202011440007.7 proposes a panoramic scanning system for digital pathological section by using laser and LED mixed light source to image, which is hopeful to shoot clearer pathological section image. However, when a medical sample or a lesion is illuminated and photographed by using a narrow-linewidth LED or a white light synthesized by laser, the obtained medical image is too colorful and distorted when reproduced on the existing LED display, and the imaging display effect is not as clear as that of an image photographed by a wide-linewidth light source for a doctor.
The main reasons for this problem are: three spectral characteristics of the narrow line width photographing light source and the wide line width display light source: there are great differences in "optical center wavelength", "spectral line width (color saturation)", and "color gamut coverage".
