A Computed tomography (CT) takes several x-rays to reveal deformities in shape and structure that are connected with blood clots, tumours, and other health problems.
Computed tomography (CT) uses x-rays to create images that show the structure of the brain and the areas of damage.
What is Computed tomography (CT) ?
A computed tomography scan is a medical imaging technique used to obtain detailed internal images of the body.
The personnel that perform CT scans are called radiographers or radiology technologists.
CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body.
CT scan can be used in patients with metallic implants or pacemakers, for whom magnetic resonance imaging (MRI) is contraindicated.
Lillian Wald was a nurse and humanitarian. She founded community nursing and coined the nurses integrated in the community as " public health nurse". She also established the very first public health nursing system. She also campaigned to have nurses in public schools.
