all the basics of x-ray scatter

medicine and healthcare 01 solid

Collimation

Influence of the field of view or collimation setting (most important setting to monitor as a technologist for scatter)

kVp

The tube potential is a determining factor in the amount of scatter.

Air gap

The distance between the patient and the detector can influence the scatter.

thickness

The object thickness has significant impact on the measured x-ray scatter

x-ray Grids

If scatter can not be reduced with other means anti-scatter grids can be used to preferentially stop scattered photons.

Bucky factor

Anti-scatter grids are used to boost the contrast but there is an associated dose penalty expressed as the Bucky Factor.

I absolutely love this website! As a Registered Radiologic Technologist I am always looking for educational material that will assist educating future Radiologic Technologists. howradiologyworks.com has become one of my favorite educational resources due to its simple (and sometimes witty) approach to educating students about the physics behind CT and XRAY.

Brian's lessons on How Radiology Works are something else. Awesome illustrations that are simple, rich and renewing. Thanks so much for undertaking such wonderful work. The reason is that most radiographers need a review of what they already should know and for students your methods are quite lovely.
