Abstract
This paper presents the first experimental results on magnetic particle imaging with full 2D encoding. The encoding speed achieved was 3.88 ms for a field of view of 1x1 cm2. Small phantoms composed of several dots each filled with 200 nl undiluted Resovist (500 mmol(Fe) l(-1)) were scanned. A resolution of better than 1 mm was achieved for a frame rate of 25 frames s(-1).
摘要
本文展示了全二维编码磁粒子成像的首个实验结果。对于1×1平方厘米的视野，实现的编码速度为3.88毫秒。对由几个小点组成的小型体模进行了扫描，每个小点填充200纳升未稀释的瑞舒伐他汀（500毫摩尔（铁）/升）。在25帧/秒的帧率下实现了优于1毫米的分辨率。
