| 摘 要： | 利用IDL对PET/CT医学图像数据进行三维可视化进行分析研究。使用表面绘制和体绘制两种绘制技术进行三维可视化，并通过结果分析比较二者的特点。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，将PET和CT两种图像形成的三维图像进行互操作，选取任一种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，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。 |

| Abstract： | The project studies the 3-D visualization of the medical images of DICOM format which are PET and CT slices based on IDL. Surface rendering and volume rendering are studied and realized. The principle of visualization based on IDL is studied. The project analyzes the data generated from PET/CT device based on IDL. Surface rendering and volume rendering are studied and realized. The 3-D images of PET and CT are put into a single interface and interoperation is allowed to operate on another image by operating on one image. This means much to diagnose in medical. At last the results are discussed, compared and analyzed. The principle of visualization based on IDL is studied. The visualization results of this project are analyzed and show that as a visualization toolkit, IDL is powerful with strong matrix handling ability in medical image processing. So the IDL language is suitable for the image analysis for researchers and doctors in image field. |
