The measurement of pointing accuracy of two-dimensional scan mirror
SPIE Proceedings, 2015Abstract The observation accuracy of space camera targ eted on ground objects is directly affected by th e pointing deviation of the two dimensional scan mirror. A plane model of the scan mirrorÂ’s normal trajectory is established when scan mirror is rotating along the rolling axis while the pitching axis remain s still.

Accuracy and Precision of In Vitro Volumetric Measurements by Three-Dimensional Sonography
Investigative Radiology, 1996A radiologist often wishes to measure organ volume or monitor changes in internal lesion volume during treatment. If this can be determined via three-dimensional ultrasound, the relative simplicity of the procedure and the decreased cost and known risks to the patient would make this method an attractive alternative to other modalities.Three ...

Three-dimensional computed tomography measurement accuracy of varying Hill-Sachs lesion size
Journal of Shoulder and Elbow Surgery, 2018The glenoid track concept has been proposed to correlate shoulder stability with bone loss. Accurate assessment of Hill-Sachs lesion size preoperatively may affect surgical planning and postoperative outcomes; however, no measurement method has been universally accepted.

Measurements of dimensional accuracy using linear and scanning profile techniques.
The International journal of prosthodontics, 1992Various measurement methods have been described for the determination of dimensional accuracy and stability of denture base materials. This investigation introduces a computerised coordinate measuring machine (CCMM) and compares it with two methods routinely used for assessment of the accuracy of fit of denture base materials.

Direct measurement of dimensional accuracy with three denture-processing techniques.
The International journal of prosthodontics, 1992The Michigan Computer-Graphics Coordinate Measurement System (MCGCMS) was used to determine the dimensional accuracy of dentures processed by three different techniques: conventional heat compression, microwave, and visible-light activation. Standardized dentures were fabricated from casts made in an RTV silicone mold.
