Sentences with phrase «emissions tomography»
Emissions tomography refers to a medical imaging technique that helps doctors see inside the body by creating images of the places where certain substances are present or active. It involves using a special camera that can detect radiation emitted by these substances, allowing healthcare professionals to track their distribution and activity in the body. Full definition
