医学影像技术的不断发展,使高分辨率CT技术广泛应用于临床。CT高分辨率扫描成像(high resolation CT,以下简称HRCT),是结合1～2mm层厚和像素大小为0.2～0.3mm的重建图像的一种技术。现将在肺部螺旋CT扫描中应用此技术的体会总结如下。
The continuous development of medical imaging technology, so that high-resolution CT technology is widely used in clinical. CT high resolution scan imaging (HRCT) is a technique that combines a reconstructed image with a layer thickness of 1 to 2 mm and a pixel size of 0.2 to 0.3 mm. The experience of using this technique in pulmonary spiral CT scans is summarized below.
