Abstract
A CT scanning device, shell and setting including having accommodation space are in shell inside is used for bearing the microscope carrier that is detected the thing, light source part with the exploring block set up in inside the shell to arrange in respectively along the horizontal direction the microscope carrier both sides, rotatory frame is still including being used for the regulation microscope carrier vertical height's elevating gear. Height through elevating gear regulation and control testee perhaps at the uniform velocity reciprocates the testee, thereby can effectively solve when light source part scans the testee because the organizational structure of lung overlaps the low problem of sensitivity that leads to in X -ray chest X -rays image, can reach the effect of spiral CT. Not only sensitivity is high, simple structure, small moreover, and low in manufacturing cost is fit for using widely on a large scale, and simultaneously, CT scanning device radiation does low, little to the human body injury.
Description
Technical field
This utility model relates to Non-invasive detection field, is specifically related to a kind of CT scan device.
Background technology
Pulmonary carcinoma is one of malignant tumor that in current world wide, M & M is the highest, related data shows, the whole world has every day dies from pulmonary carcinoma more than 4000 people, and the whole world exceedes the summation because of breast carcinoma, colon cancer, renal carcinoma, hepatocarcinoma, skin carcinoma and carcinoma of prostate death toll because of the number of lung cancer death.But, owing to there is symptom and medical patients with lung cancer many genus late periods, poor prognosis.
Some national patients with lung cancer survival rate of 5 years reaches more than 20% now, but China is far below this, so it may be necessary low-dose CT (ComputedTomography, computerized tomography) the examination early stage of lung cancer to improve this present situation.In recent years result of study shows, low-dose CT (LDCT) annual examination can find 0 ~ I phase pulmonary carcinoma, and after excision, the survival rate of 10 years can reach 92%, and all untreated I phase patients will be dead in 5 years.Therefore, for the high-risk group of pulmonary carcinoma, be i.e. advanced age or smoking period is longer, special occupation and family medical history crowd etc., carry out regular screening lung cancer and be very important.
Since need examination, just need to have easy, easy, inexpensive, responsive, special and the examination technology of feature such as easily to repeat, wherein easy, special, responsive, easily repeat and noinvasive etc. particularly important.Noinvasive examination technology mainly contains the biochemical marker inspection of imaging examination, bronchoscopy, expectorant inspection, serum and other body fluid.Iconography at present for pulmonary carcinoma detects mainly X-ray Chest X-rays (comprising Chest X-rays, rabat, DR) and spiral CT.
X-ray Chest X-rays is not owing to having three-dimensional resolution capability, and sensitivity is not high, and sensitivity and specificity are the important performance characteristic weighing diagnosis quality.For early screening, the height of sensitivity seems particularly important.Based on the sensitivity of Imaging Technology examination pulmonary carcinoma, reflect this technology for the detection of different tumor size and resolution capability.Due to breast lung tissue structure overlap in the picture, the sensitivity of X-ray Chest X-rays is not high, approximately can see the shade of 6mm at present, then insensitive to less shade.The resolution of spiral CT is high, but radiation dose is comparatively large, and machine is bulky, cost intensive, is still limited to large hospital as health check-up project, is not almost equipped with at vast basic hospital.Therefore, this two series products has certain limitation.
