The critical nature of health care demands high performance levels from medical equipment. To ensure these performance levels are maintained, medical physicists and biomedical engineers conduct a range of measurements on equipment during acceptance testing and on-going quality assurance programs. Wherever there are measurements, there are measurement uncertainties with potential conflicts between the measurements made by installers, owners and occasionally regulators. Prior to 1993, various…

TLDR
The method used to determine the uncertainty of a measurement is widely varied and the more systematic approach is to determine random and systematic errors and summate these together to give the final uncertainty in the value of the parameter you are measuring.

On the uncertainties in effective dose estimates of adult CT head scans.
TLDR
This study calculates the uncertainty of effective dose estimates produced by three computer programs (CT-EXPO, CTDosimetry, and ImpactDose) and one method that makes use of dose-length product (DLP) values in accordance with an internationally recognized uncertainty analysis guide.
Uncertainties associated with signal measurements from solutions and from solid substrates using luminescence based methods
A careful study was performed to evaluate and compare uncertainties associated with the measurement of luminescence from chrysene by using fluorimetry in solution and by using solid surface
A Practical Way to ISO/GUM Measurement Uncertainty for Analytical Assays Including In-House Validation Data
TLDR
This contribution outlines the estimation of measurement uncertainty of analytical assays in a practical way by considering the heritance of uncertainties according to the ISO Guide to the expression of uncertainty in measurement (ISO/GUM) approach and the accuracy study coming from the in-house method validation.
Measurement uncertainty analysis of low-dose-rate prostate seed brachytherapy: post-implant dosimetry
TLDR
It was found that variations in contouring the target tissue made the largest contribution to D90 uncertainty, while the uncertainty in seed source strength made only a small contribution.
ISO-GUM and Supplements are Utilized for QA of BCA Data
TLDR
ISO-GUM is now useful in order that the Blood Chemical Analysis (BCA) may also grade up the reliability of an analysis result with assurance performed.
Effective Dose Estimation for U.S. Army Soldiers Undergoing Multiple Computed
TLDR
The research addressed a knowledge gap in assigning effective doses from computed tomography when machine parameters knowledge is either unknown or incomplete through the development of a new method of estimating the effective dose from CT through the use of regression models incorporating theuse of patient parameters as opposed to machine specific parameters.
