Testing the trueness of circular surfaces: a simple holographic method
Applied Optics, 1979A new holographic method where the object motion or variation is transferred to some other subject (we can call it a probe) is suggested. The theory is developed and verified experimentally for an Ealing precision self-centering lens holder as the probe. The method possesses many advantagesover the conventional holographic interferometry, some of which

Evaluation of trueness and precision of 3 face-scanning devices
American Journal of Orthodontics and Dentofacial OrthopedicsThis study evaluated the trueness and precision of three 3-dimensional facial scanning devices-MetiSmile (MS), Revopoint Miraco Plus (RMP), and Qlone Dental application (QA) using an iPhone 15 Pro.Forty-seven participants were scanned using MS, RMP, and QA under standardized conditions.

Trueness in the measurement of haemoglobin: consensus or reference method?
Clinical Chemistry and Laboratory Medicine, 2012For the measurement of haemoglobin a reference method exists: the haemiglobincyanide method. However, a Dutch external quality assessment organization does not use this method in the evaluation of trueness of results. The aim of this work was to assess whether trueness was compromised by the use of a consensus value.Five Cell Dyn Sapphires (Abbott) in ...

Influence of laser ablation parameters on trueness of imaging
Applied Surface Science, 2015Influence of laser ablation conditions on limit of detection, spatial resolution and time of analysis was studied for laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) applied to elemental mapping. Laser repetition rate and laser fluence were investigated in tapeworm thin section to attain optimum ablation rate yielding ...

Accuracy controls: assessing trueness (bias).
Clinics in laboratory medicine, 2013Testing quality control samples is routine in the clinical laboratory but typically these are precision controls that monitor only the reproducibility (random error) of an assay and not trueness/bias (systematic error). To assess bias, accuracy controls that address both systematic error (trueness) and random error (precision) are needed.

Study of trueness in CAD/CAM complete dentures
2022Aim: to compare the trueness of 3D printed versus milled complete denture bases. Materials and methods: study used frasaco (Tettnang, Germany) edentulous model of the upper jaw which was duplicated using silicone duplicating material. Eight casts were poured with type 3 dental stone.
