Thermography – shows surface map of temperature by measuring emitted infrared light.
On left – normal hands – fingers and blood vessels appear warm
On right – Raynaud’s syndrome – reduces blood flow to fingers means they appear cold.

First clinical x-ray taken by Wilhelm Roentgen on 22 Dec 1895, of his wife’s hand, showing wedding ring and bones of fingers.
This was taken with a 15 minute exposure; a modern x-ray image has an expose of ~10-ms (CHECK)

This is a CT image which has been processed by computer so that only the bones and the muscles are shown.
The second metatarsal bone (the bone that Beckham broke) is shown.
