CT scan may provide: 1) accurate measurement of the impact of mechanical ventilation on hyperaeration and reaeration/recruitment, being the most objective technique currently available to set mechanical ventilation and identifying patients for extracorporeal lung support; 2) the amount of lung edema, ...
CT lung screening is a noninvasive, painless procedure that uses low-dose x-rays to screen the lungs for cancer in just 30 seconds. A CT lung screening allows the radiologist to look at different levels, or slices, of the lungs using a rotating X...
这个过程在一个多层螺旋计算机断层扫描(CT)扫描仪中进行,可以检查出比标准X光胸片更小的结节或肿瘤。肿瘤或结节是在肺上生长的细胞群,它可以是良性的(非癌性)或恶性的(癌性的)。通过CT肺筛查,可以发现早期恶性肿瘤,从而可以定位及早期治疗,增加存活率。 CT lung screening is a noninvasive, painless procedure ...
CT Scans and Lung Cancer Small or slow-growing nodules (小结节) discovered on a lung scan are unlikely to develop into tumors over the next two years, researchers reported on Wednesday. The findings reported in the New England Journal of Medicine, could help doctors decide when to do more ...
An offline setup correction protocol was applied to reduce systematic setup errors.Results: For all patients, the skin marks defined the planning CT scan isocenter to within 卤 1.5 mm in each of the three main directions. Random setup errors at the treatment unit were 1.8, 2.0, and 1.9 mm ...
Both microCT systems were calibrated for Hounsfield Units (HU) using phantoms. In the Quantum Fx system, the phantom consisted out of a 5 mL plastic tube filled with 2 mL of water and 3 mL of air. For the SkyScan1076 the phantom consisted in 1.5 mL air in a 50 mL tube filled with...

Lung cancer is considered more serious among other prevailing cancer types. One of the reasons for it is that it is usually not diagnosed until it has spread and by that time it becomes very difficult to treat. Early detection of lung cancer can signific
