Interpolation
Interpolation (medicine)
Interpolation (pronunciation: /ˌɪntərpəˈleɪʃən/) is a term used in various fields of medicine, including radiology, cardiology, and neurology. It refers to the process of estimating a value within two known values in a sequence of values.
Etymology
The term 'interpolation' is derived from the Latin 'interpolare', which means 'to polish, alter, falsify'. However, in the context of medicine, it is used to describe a method of estimating or determining values.
Usage in Medicine
In radiology, interpolation is used in the reconstruction of images from raw data obtained from imaging modalities like CT and MRI.
In cardiology, the term is used to describe a phenomenon where an extra heartbeat is inserted into the normal rhythm of the heart, often seen in conditions like atrial fibrillation.
In neurology, interpolation is used in the context of nerve conduction studies to estimate the velocity of nerve conduction.
Related Terms
- Extrapolation: This is a similar concept to interpolation, but it involves estimating values outside the known range of data.
- Interpolated PVC: This is a type of premature ventricular contraction that occurs without interrupting the normal heart rhythm.
- Image Reconstruction: This is the process of creating a visual representation from raw data, often using methods like interpolation.
