Medical thermal film is an imaging material used in the diagnosis of human diseases, which can more accurately show the lesions and variations of internal organs, bones and soft tissues of the human body. Medical film provides a reliable basis for clinical medical diagnosis. The new technology is adopted, which has the characteristics of high sensitivity, good definition, large tolerance and good versatility.

Medical thermal film imaging principle: medical thermal film has three layers of photosensitive emulsion layer, in these emulsion layer also identify different inorganic compounds that can generate dyes, called black coincidence agent (color former). They are colorless by themselves, but can be decomposed into colored dyes in conjunction with the oxides of the black developer when black is developed.

The coincidence agent contained in the lower blind color emulsion forms yellow when black is developed, the middle layer forms magenta, and the upper layer forms cyan. This is the developed black medical film we lost. After expansion or reduction, projecting the image onto the photographic paper may be the reverse development of the reverse film. The yellow of the lower layer of the medical film changes to its complementary blue, the first layer of the two ends changes to green, and the upper layer changes to white. We lose the same black photo as the natural form or the bright reverse film. This is the fundamental process of black medical film recorded images Ming.

The consequence is that the dark (thick) part on the negative image is the part with more exposure. The bright (thin) part is the less exposed part. The fully lit part is the part that has not been irradiated by light. This is the fundamental process of color medical film recording images.

The medical film we developed uses a blue polyester film base. The front of the medical thermal film is coated with a photosensitive emulsion, and the back of the film is generally coated with an anti-halo layer. Film layer rich, good clarity. Medical film is suitable for different medical images. Such as: magnetic resonance imaging, tomography, digital subtraction, isotope radiation, ultrasound imaging, etc. Film can be used in high temperature processing machine processing, can also be room temperature manual processing.

Its medical thermal film is more suitable for the environment of temperature 18-2 degrees Celsius and humidity 50-60% RH. When medical film is taken out or loaded from the package, artificial artifacts and static electricity caused by folding, gravity squeezing and friction between medical films should be avoided. During contact with the film, keep your hands clean and dry to avoid contact between wet hands and the film.
