Micro-Focus X-Ray
X-Ray equipment in which the focal spot size is less than 100 µm is referred to as
microfocus unit. Advanced micro-focus units have a focal spot size as low as 5 µm which is
achieved by focussing the electron beam on the target in combination with sufficient cooling
to avoid overheating.
Micro-focus radiography facilitates to observe the minute details of the object through
production of magnified X-ray images, which in turn enhances the flaw detection capability
which improves reliability in comparison to conventional radiography. Micro-focus X-ray
systems having focal spots that approach a point source are useful in obtaining very high
resolution images due to the negligible penumbra effect.
The X-ray source generates a continuous beam of X-rays from the very small focal point.
The beam passes through the sample placed on the manipulator turntable, and casts an Xray projection onto the detector sensor. The sensor converts the transmitted X-ray
projection into a visible greyscale image, which is displayed on a monitor. The magnification
of the sample depends on its position between the X-ray source and detector. Moving the
sample towards the X-ray source increases the magnification and improves the spatial
resolution by increasing the number of pixels over which the X-ray image is projected. Even
when operating at maximum magnification, the micro-focus X-ray spot ensures the image is
always sharp. The associated software enables contrast enhancement and image
integration.
