This study presents a low-cost, extremely practical, and easy-to-operate composite instrument for measuring height. This instrument uses the level-, distance-, and heightmeasuring devices typically employed in construction works for further integration. Because most instruments used in construction and architecture are expensive and have only single functions, the system developed in this study...

BACKGROUND Height is an important health assessment measure with many applications. In the medical practice and in research settings, height is typically measured with a stadiometer. Although lasers are commonly used by health professionals for measurement including facial imaging, corneal thickness, and limb length, it has not been utilized for measuring height. The purpose of this feasibility...

Height is fundamental to assessing growth and nutrition, calculating body surface area, and predicting pulmonary function in childhood. Its measurement is hindered by muscle weakness, joint, or spinal deformity. Arm span has been used as a substitute, but is inaccurate. The objective of the study was to identify a limb measurement that precisely and reproducibly predicts height in childhood. Ma...

The measurement kit of the ADA-CAT (Americans With Disabilities Act-Compliance Assessment Toolkit) consists of measurement instruments, such as a measuring tape, a sound level meter, a light level meter, and a magic slope block. Perhaps the most important tool is the measuring tape for length and height measurement as distances are used so prolifically in the ADA assessment process. Currently, ...

OBJECTIVE To evaluate the reliability of 3-dimensional ultrasound (3D-US) for the measurement of choroidal melanomas. DESIGN Retrospective case series. PARTICIPANTS Forty-two consecutive cases of choroidal melanoma imaged with 3D-US. METHODS Tumor measurements obtained with ophthalmoscopy, transillumination, standard ultrasound techniques, 3D-US, and pathological studies. Tumor diameters,...
