X-ray imaging

Definition

X-ray imaging is a medical imaging technique that uses ionizing radiation to create images of the inside of the body, primarily for diagnosing and monitoring various health conditions. This technology has evolved significantly since its discovery, becoming a cornerstone in modern medicine for visualizing bones, organs, and tissues. It is crucial in understanding how medical imaging has developed historically and how it remains relevant in the analysis of biomedical signals today.

5 Must Know Facts For Your Next Test
