X-rays were first discovered by Roentgen in 1895 and went into widespread use for medical purposes very soon afterwards.

X-ray of a shoulder

Recent years have seen an explosion of development in medical imaging with the availability of complex ultrasound, CT and MRI scanning.

Digital X-ray

Even plain x-rays have evolved and instead of being printed on film are now more commonly viewed as digital images that can be manipulated on a computer workstation and sent around and between hospitals or around the world on computer networks such as PACS (picture archiving and communications systems).

X-ray of the chest

Ordinary X-rays include those of the chest, abdomen and limbs as well as X-ray based techniques such intravenous urograms and barium enemas. The most widely used method of examining the small bowel is with a barium examination.
