Computed Tomography angiography has become a major diagnostic imaging technique in patients suspected of having aortic diseases. However, aortic CTA needs a long scanning range, usually from subclavian artery to the origin of femoral arteries, which therefore includes high radiation dose. Besides of diagnostic value, aortic CTA is also used for follow-up as well as pre- and post-operative assessment...
A facile strategy for the large‐scale fabrication of Bi2S3 nanodots is presented. Surface modification and control over the size of the nanodots is easily achieved. The as‐prepared hydrophilic Bi2S3 nanodots exhibit long in vivo circulation time and, more significantly, a contrast efficacy higher than that of the clinical iodinate agent without any adverse effect.
To achieve a effective segmentation for liver cancer CT image, this paper utilizes comprehensive the edge detection, the watershed algorithm and region merging approach, propose a segmentation method of liver cancer CT image based on the watershed algorithm, gain a better effect in the course of liver cancer CT image segmentation, and solve effectively the over-segmentation phenomenon of the traditional...
