Calibration
Calibration
Calibration (pronunciation: /ˌkælɪˈbreɪʃən/) is a process in the field of medicine and science that ensures the accuracy of equipment measurements. The term originates from the Middle English word "calibre," which means "standard of measurement."
Definition
In a medical context, calibration is the process of adjusting the output or measurement on a device or instrument to match the value indicated by a reference standard. This process is crucial in medical testing and research to ensure that the results are accurate and reliable.
Process
The calibration process involves comparing the measurements of two instruments, one of which has a known magnitude or correctness (the standard), against the instrument being tested (the device). The device is then adjusted to match the standard. This process is repeated until the device's measurements are within an acceptable range of the standard.
Importance in Medicine
In medicine, calibration is essential for ensuring the accuracy of medical devices and equipment. This includes everything from blood pressure monitors to MRI machines. Without proper calibration, these devices could provide inaccurate results, leading to potential misdiagnoses or improper treatment.
Related Terms
- Standard: A known magnitude or correctness used in the calibration process.
- Device: The instrument being tested and adjusted in the calibration process.
- Accuracy: The degree to which a measurement, or an estimate based on measurements, represents the true value of the attribute being measured.
- Precision: The degree to which repeated measurements under unchanged conditions show the same results.
