A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

Even measurements of parts of the body, such as a finger, can be used to estimate the stature. [3] [4] The principle behind this forensic anthropology technique is the fact that for a given combination of age, race, and gender there measurements of different body parts which have a relationship to the stature. This relationship between the ...
The mid-upper arm area (MUAA) is an estimation of the area of the upper arm. It is derived from the MUAC using the following formula: [3] [4] = [3] [4] [6] The mid-upper arm muscle circumference (MUAMC) is an estimation of the circumference of the bone and muscle portions of the upper arm.
Fistmele - the measure of a clenched hand with the thumb extended; Gradus - Ancient Roman step; Hand - breadth of a human hand; Klafter - German measure of outstretched hands; League - the distance a person can walk in an hour (by one definition) Orgyia - Ancient Greek fathom; Parasang - the distance an infantryman could march in a predefined ...
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.
In medicine, peripheral quantitative computed tomography, commonly abbreviated pQCT, is a type of quantitative computed tomography (QCT), used for making measurements of the bone mineral density (BMD) in a peripheral part of the body, such as the forearms or legs as opposed to QCT that measures bone mineral density at the hip and spine. It is ...
Classifications of female body sizes are mainly based on the circumference of the bust–waist–hip , as in 90-60-90 (centimeters) or 36–24–36 (inches) respectively. In this case, the waist–hip ratio is 60/90 or 24/36 = 0.67. Many terms or classifications are used to describe body shape types:
Bone density. The basic principle of single-photon bone mineral density measuring instrument is to calculate the attenuation degree of single-energy gamma photon beam through bone tissue. The more attenuation degree is, the more absorbed by bone minerals, the more bone mineral content and the higher bone mineral density are.
