Abstract
A new technique converts a standard biased x-ray tube into a microfocal spot tube with a clinically useful loading capacity. If the tube is pivoted exactly through the focal spot, the film can be scanned with a 5-10 cm wide beam and cover a 17-inch field. Then the target angle can be decreased to a few degrees. The width of the focal spot can be decreased using a grid bias.
摘要
一种新技术可将标准的有偏置的X射线管转换为具有临床可用负载能力的微焦点管。如果该管恰好绕焦点旋转，那么胶片可用5至10厘米宽的光束进行扫描，并覆盖17英寸的视野。然后可将靶角减小到几度。使用栅极偏置可减小焦点的宽度。
