病人头部的立体图象渐渐地出现在屏幕上,犹如被利剑劈开一般,看上去几乎与幽灵的模样毫无差别。从被展现的病人头部的断面图象,人们能看到头骨、包括各种类型组织以及大脑自身的解剖学轮廊。随着在脑的内部突然出现明亮的彩色区,这种图象也就快完成了。这个彩色标记正是医生们所要寻找的:肿块。通过对计算机图象的坐标进行重新计算,倾斜以及沿不同的方向转动,有可能很精确地确定肿块的确切大小和位置。因此,这种方法为外科手术提供了必须的重要资料。在颅骨顶部钻一个小洞,然后把含有适当剂量放射
Stereoscopic images of the patient’s head gradually appear on the screen as if they were split by a sword and appear to be almost indistinguishable from the appearance of a specter. From the cross-sectional image of the patient’s head being presented, one can see the skull, including various types of tissues and the anatomy of the brain itself. With the sudden appearance of brightly colored areas inside the brain, the image is almost complete. This color tag is what the doctors are looking for: lumps. By recalculating the coordinates of the computer image, tilting and turning in different directions, it is possible to determine precisely the exact size and position of the mass. Therefore, this method provides essential information for surgery. Drill a small hole in the top of the skull and radiate it with the appropriate dose
