磁共振成像的三维图形定位的实现

3D Graphics Localization in MRI

在做磁共振成像时,根据需要医生应该能够对病人任意的解剖部位以及这个部位的任意方向进行扫描,为此需要得到扫描的中心位置、频率编码方向、相位编码方向等坐标信息。这个过程是比较繁琐的,我们开发出一个定位子系统,使得医生可以通过图形定位的方式来确定这套参数,做到所见即所得。

During MRI scanning, operator will scan any anatomic part of patient. This step needs center frequency, frequency encoding direction and phase encoding direction etc. It a complex step. We developed a graphics localization system to get these parameters by GUI, so all the parameters in localization can be obtained in WYSIWYG （what you see is what you get）.
