Description
Technical field
The present invention relates to lung cancer detection technical field, specifically a kind of lung cancer sample rapid detection method.
Background technique
Lung cancer is the most common malignant tumour of countries in the world today, and the death rate occupy the first place of various tumours, to the mankind
Health and lives constitute great threat.In China, lung cancer about causes 500,000 deaths every year, accounts for entire cases of cancer
28%, and 5 annual survival rates of lung cancer patient only have 14%.However, researches show that the postoperative 10 years survival rates of I phase lung cancer can reach
92%.Therefore, the key for reducing the patients with lung cancer death rate is to early diagnose and early treatment, the Lung neoplasm of the early stage of lung cancer detect
As key, cooperate treatment appropriate, the survival rate of patient can be improved to 50%.
5 kinds of basic methods of sieving and diagnosis lung cancer at present, x-ray chest radiograph are preferred screening means, secondly be exactly CT, MIR and
PET.CT is considered as the best approach --- " goldstandard " for detecting Lung neoplasm.However, because economic, convenient and radiological dose is fitted
Medium reason, x-ray chest radiograph are more often used, in fact, the almost all of early stage of lung cancer is found by rabat, but to dept. of radiology
It is a highly difficult task based on the rabat discovery early stage of lung cancer for doctor.It is nowadays accepted that the most universal in the world, warp
Ji and traditional method of lung cancer diagnosis is by chest X- light emission line image (the mainly number caused by CR/DR technology
The X- light emission line image of change) diagnose the early stage of lung cancer.At present in Economic contrast developed regions, chest is all carried out in health screening
X-ray technology checks whether there is pulmonary disease.However a large amount of generaI investigation chest pictures are diagnosed, for radiologist
It is a challenge.
With the arrival of cloud era, big data is also by originally more concerns, the image list of previous hospital's pulmonary cancer diagnosis
Solely storage, each hospital can only be trained doctor according to the influence that oneself stores, improve the diagnosis capability to lung cancer, effect
Slow effect, and since sample is few, it is difficult to achieve the purpose that quick, Accurate Diagnosis, if big data can be based on by all diagnostic graphs
As carry out image procossing, and by cloud computing concentrate carry out Classification and Identification, will greatly improve pulmonary cancer diagnosis efficiency and accurately
Degree.
