初级PET/CT交互系统设计
摘要
本课题研究第四代编程语言IDL对PET/CT医学图像数据进行三维可视化处理的应用,对数据进行交互分析,包括断面显示、融合显示以及三维可视化分析研究。IDL拥有丰富的分析工具包,强大的矩阵运算能力,高速的图形显示技术,特别适于大型数据集的分析处理。 PET/CT是当前医学影像中最先进的设备,结合了PET和CT二者的优点,能精确定位病灶。IDL与PET/CT的结合,必将大大促进医学影像学的发展,为医学事业做出巨大的贡献。
本课题以IDL为基础,对PET/CT数据分析处理,使用表面绘制和体绘制两种绘制技术,率先将PET和CT两种图像形成的三维图像进行互操作,选取任一图像的部位即可同时定位另一种图像的相应截面。这对临床医学的诊断有重要意义。最后对试验结果进行讨论、比较、分析。
通过本课题研究,也说明IDL,作为医学图像处理和三维可视化工具,具有强大的矩阵运算能力、面对医学数字图像具有快捷高效读写和处理能力、简洁的编程风格等优点,因而非常适用于医学影像的研究人员和医生应用。

The project studies the 3一D visualization of the medical images of PET/CT medical images using the forth generation programing language this proj ect,the IDL language is used to analysize the PET/CT medical image data interactively,including slices display separately, integrate display and 3一D visualization of the are abundant analysis tools with strong matrix calculating ability for speed image display technology is used expecially for analysis of huge amount of is the most advanced device for medical devices up to now bining the advantages of both PET and CT and it can fix the nidus of PET/CT and IDL will ultimately enhance the development of the medical image technology and make great effort for the medical enterprise.
The proj ect analyzes the data generated from PET/CT device based on rendering and volume rendering are studied and realized. The 3-D images of PET and CT are firstly put into a single interface and
