Technical field
This utility model belongs to the area of computer aided observation analysis The Application of Technology field of medical image, be specifically related to a kind of computer auxiliary medical image observing system, this system can cooperate medical film viewer to use, and is that a kind of auxiliary doctor carries out the instrument that medical image is read sheet.
Background technology
Medical film viewer is to observe the medical image film, as the main tool of X-ray film, CT image print film and nuclear-magnetism image printing film etc.The quality of diagnosis of film depends on the brightness of film viewer and the quality of film to a great extent, promptly sees the lighting condition of sheet, the definition and the intensity profile of film.The slight change of this condition also can influence the observability and the contrast of image film details.Yet the quality of domestic a lot of film viewers and film is also not very good at present, has influenced the clinician and has utilized medical film viewer observation medical image film to diagnose.
Because the restriction of technical factor, at present in a lot of hospitals based on the diagnosis of the film part that also comes with some shortcomings, main weak point comprises: (1) film viewer does not have the cropping device, can't eliminate the serious interference of negativ-effect light; (2) there is the recognition blind area in film viewer luminance shortage; (3) film viewer brightness is unadjustable, is difficult for and the other light sources of readding the sheet environment balances each other; (4) some local detail naked eyes is difficult for differentiating on the film image.In view of in some cases, when very dark, utilize common medical film viewer can't clearly obtain the contained useful information of film as the film details, many doctors need read sheet by magnifier.Even now can solve the problem that naked eyes are difficult for the resolution image details to a certain extent, but when having amplified useful information, also amplified noise signal like this, the contrast of image and brightness are not strengthened, and observed effect may still can not be satisfactory.Someone has developed a kind of cropping film viewer, can solve the problem of existence to a certain extent, but because the limitation of prior art level, for second-rate film (crossing bright or dark excessively), even use the cropping film viewer, the clinician also can't clearly obtain interested area information, causes can't making precise diagnosis in some cases.
Summary of the invention
The purpose of this utility model is to provide a kind of computer auxiliary medical image observing system, and this system can help the doctor to read the medical image film, improves the accuracy of readding sheet.
A kind of computer auxiliary medical image observing system that this utility model provides is characterized in that: this system comprises probe and image processing apparatus; Probe comprises to be gathered cover and is fixed in the photographic head of gathering the cover end, and photographic head links to each other with image processing apparatus by data wire; Image processing apparatus is the data processor that is mounted with data acquisition module, zoom module, Image Enhancement Based piece, parameter measurement module and display module.
Photographic head is used to absorb the region of interest area image and transfer of data is arrived data acquisition module, data acquisition module is used to extract the data of photographic head picked-up and generate corresponding image, and gives zoom module, Image Enhancement Based piece and/or parameter measurement module with image data transmission; The zoom module is used for zoom; The Image Enhancement Based piece is used to regulate the contrast of image and strengthens brightness of image, the parameter measurement module is carried out measures of quantization by the proportionate relationship of determining the distance of image on the distance on the screen and film to image information, and display module is used for the parameter of image or measurement is submitted to the user.
When this utility model system uses, probe is attached to the film surface obtains data, gathering cover can keep distance and angle between photographic head and film constant, gather cover simultaneously and can block the exterior light photograph, make illumination that photographic head receives mainly from the film viewer light source that sees through film, played the effect of cropping to a certain extent.Zoom module in the image processing apparatus can solve the problem that naked eyes are difficult for the resolution image details; The Image Enhancement Based piece can strengthen brightness of image and contrast, has improved picture quality, is convenient to lesions position is carried out primary part observation, has solved the problem of film viewer luminance shortage to a certain extent.In addition, use this image processing apparatus can also manually adjust window width and window position, help observing the normal structure structure or the pathological changes details of different densities; The parameter measurement module of measuring distance, angle, area etc. helps the clinician local detail is carried out quantitative analysis, can understand information such as corresponding physical distance by the information such as pixel distance on the photographic head imaging plane effectively.Therefore, this utility model can strengthen the readability of film information, and sheet precision and quality are read in auxiliary doctor's raising, have solved the low problem of sheet precision of readding that causes owing to the film viewer luminance shortage to a certain extent.
