Abstract

We have developed a method that allows us to place regions of interest on X-ray CT (XCT) images that are automatically adjusted to positron emission tomography (PET) images from the same patient. A face mask with landmarks was used during PET and XCT studies for matching slice positions between PET and XCT. Anatomical locations in different images of the same slice can be accurately adjusted using the landmarks and a video system. In our clinical experience misadjustments of the slice position are on the average less than 2 mm in axial distance and 1.0 degrees in slice angle. The method is easily applicable to any PET or XCT device.

摘要

我们已经开发出一种方法，该方法使我们能够在X射线计算机断层扫描（XCT）图像上放置感兴趣区域，这些区域会自动与来自同一患者的正电子发射断层扫描（PET）图像进行匹配。在PET和XCT研究期间，使用带有标记点的面罩来匹配PET和XCT之间的切片位置。利用标记点和视频系统，可以精确调整同一切片不同图像中的解剖位置。根据我们的临床经验，切片位置的调整误差在轴向距离上平均小于2毫米，在切片角度上平均小于1.0度。该方法易于应用于任何PET或XCT设备。
