Measurement Accuracy of Image Pattern Correlation Method

Novel MTF Measurement Method for Medical Image Viewers Using a Bar Pattern Image

A novel MTF(modulation transfer function) measurement method using a bar pattern image for medical image viewers such as DICOM viewer was developed. A bar-pattern image produced by a personal computer was displayed on a cathode-ray-tube (CRT) display and was imaged with a high resolution single-lens reflex digital camera equipped with a close-up lens. The discrete blurred square-waveform data a...

Abstract         Background and Objective: According to recent changes in diagnostic criteria for diabetes, the harmonization of results obtained from various methods and systems by considering their accuracy and precision is essential. This study aimed to evaluate the accuracy, precision and consensus of some routine laboratory glucose kits in co...

Evaluation of Accuracy, Precision and Agreement of Five Hba1c Measurement Methods with HPLC Reference Method

ABSTRACT         Background and Objective: The current challenge of diabetes mellitus is to prevent its complications. These complications are directly associated with hyperglycemia in diabetics. The HbA1c measurement is essential for long-term glycemic control. Synchronization of HbA1c measurement is important in order to avoid discrepancies between resu...

Estimation of Machining Accuracy by Measurement of Surface Texture Pattern

Digital Image Correlation combined with Electronic Speckle Pattern Interferometery for 3D Deformation Measurement in Small Samples

The small size of mesoand microelectromechanical systems (MEMS) devices presents several challenges for full-field deformation measurements. A hybrid system combining Digital Image Correlation (DIC) for in-plane deformation and Electronic Speckle Pattern Interferometry (ESPI) for out-of-plane deformation measurements has been developed for working with these small size scales. Measurement of th...
