There are two databases with images you can download to use in your assignments and presentations.
Britannica Image Quest has images of professionals performing scans and scan images. This is a good place to find stock photos of patient interactions and equipment. There are a ton of images!
Example from Britannica Image Quest:
Stedman's Online: Select the Illustrations tab and Nuclear Medicine to find some images (fewer than Britannica). There are also some useful anatomy colour plates.
You need to go into Search Tools and only use ones that are "Labelled for reuse" (either with or without modifications - i.e. are you adding or removing something from the original picture?). Since it is coursework, it counts as noncommerical use.
You still need to give the original creator credit for their work by using a citation.

Nope, YouTube doesn't own the videos either!
You would need to contact the original creator of the video to ask for permission before using it.
To save you time and effort, use the Library's video databases when possible. These videos have been cleared for class use.
