A medical image intensifier is a device used to enhance and magnify medical images, and it consists of the following main components:
Light source: Medical image intensifiers usually use visible light or infrared light as the light source. The light source produces light that illuminates the object or tissue being inspected and provides an amplified signal.
Optical system: The optical system of the image intensifier consists of lenses, objective lenses and eyepieces. They work together to focus and amplify light to increase the brightness and clarity of images.
CCD/CMOS photosensitive device: Medical image intensifiers usually use high-sensitivity CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide-Semiconductor) photosensitive device. These photosensitive devices convert light signals into electrical signals and electronically amplify them to enhance the brightness and contrast of images.
Signal processing unit: The signal processing unit is used to amplify, filter and enhance the electrical signal obtained from the photosensitive device. It can improve the quality of the image, and adjust the brightness, contrast, color and other parameters of the image according to the needs.
Display device: The display device is used to display the enhanced image, and the common ones are liquid crystal display, CRT display or projector. The display device can display images with high resolution and high contrast, enabling doctors or operators to observe and diagnose clearly.
Control circuit and interface: The image intensifier also includes a control circuit and interface, which are used to adjust and control the working parameters of the intensifier, such as gain, exposure time, image format, etc. At the same time, they provide connection interfaces with other devices for functions such as data transmission and image storage.
In summary, the main components of a medical image intensifier include a light source, an optical system, a CCD/CMOS photosensitive device, a signal processing unit, a display device, and a control circuit and interface. These components work together to enable doctors or operators to observe and diagnose medical images more clearly, improving diagnostic accuracy and medical quality.
