Right censoring occurs when the observation of a subject's event time is incomplete due to the study ending or the subject leaving the study before the event occurs. It is a common issue in survival analysis and requires specific statistical techniques to ensure unbiased estimation of survival functions and hazard rates.
A Computed Tomography (CT) scan is a medical imaging technique that uses computer-processed combinations of multiple X-ray measurements taken from different angles to produce cross-sectional images of specific areas of the body, allowing for detailed examination of internal organs, bones, soft tissue, and blood vessels. It is widely used for diagnostic purposes, guiding treatment plans, and monitoring disease progression due to its ability to provide more detailed information than standard X-rays.
Planar imaging refers to the process of capturing two-dimensional images that represent the distribution of specific elements within a plane, often used in medical diagnostics and material analysis. By analyzing these planar images, professionals can obtain crucial insights into the structure and composition of objects or tissues without the need for invasive procedures.
