Description

Body composition analysis system with image scanning function

This creation system is related to body composition analysis technology, especially a body composition analysis system with image scanning function.

Body Composition can be assessed in several different ways, including: advanced medical imaging equipment such as dual-energy X-ray absorptiometry (DXA), computed tomography (CT), and magnetic resonance imaging (MRI), which can It provides high-precision evaluation, but the detection cost is high and requires special personnel to operate. In addition, because the radiation dose of computed tomography can reach hundreds of times that of ordinary X-rays, there are limitations in its use. In contrast, dual-energy X-ray absorptiometry has extremely low radiation dose and high accuracy, and has become the gold standard for body composition analysis. . Other methods such as Underwater Weighing, Air Displacement Plethysmography (ADP), Skinfold Measurement, Circumference, Isotope Dilution, Ultrasound Measurement method, potassium-40 measurement method (Potassium-40 Counting) and bioimpedance method (Bioelectrical Impedance Analysis-BIA) and other methods.

Among them, the bioelectrical impedance method is currently the most commonly used method for estimating human body composition due to its fast, simple, relatively safe and non-invasive characteristics. The bioimpedance method is that the subject is lying or standing on the body to form a measuring instrument, and the subject's limbs are in contact with the body to form the electrodes of the measuring instrument, and a small amount of current is passed through. The characteristics of different resistance and reactance values are generated for currents of different frequencies, and the body water content can be obtained. The traditional method usually matches the age, gender, weight, height and other information of the subject, and obtains various components of the human body from the estimation equation, including the body. Fat weight, non-fat weight, total water content, intracellular and extracellular fluid volume, etc., and then further calculate the ratio or content of bone, muscle, fat and other tissues.

In recent years, the application of 3D body scanning technology for body composition analysis has become more and more common, and it has become an emerging research direction; for example, in US Patent No. US 2019/0223788 A1, in order to solve the problem of directly calculating body fat by volume in 3D imaging The main technology proposed is to use the three-dimensional body model to determine the body volume and geometric shape, and to establish a multi-segment human body impedance model including cylindrical or conical forms. model, especially the shoulder joint, upper arm, forearm, hand, thigh, knee joint or calf, etc. Next, measure the impedance of the human body with at least two electrodes to obtain the detailed impedance of the body segment in particular. The fractional body fat content is added to obtain the total body fat content.

However, the body photography provided by the above patent is measured by standing and touching the electrodes with both hands, which has at least two shortcomings to be improved: 1. When the subject stands on the rotating disk and performs a rotating scan, it is inevitable that there will be a swing or a change in attitude, which will affect the resistance and reactance values measured by the body composition measuring instrument, resulting in inaccurate measurement results. 2. When the subject touches the electrodes with both hands, the angle between the arm and the torso will be formed. When the angle is too small, the skin of the arm will touch the skin of the torso, or the clothing will have contact problems, which will affect the body composition measuring instrument. Errors in resistance and reactance values result in unrepeatable and inaccurate measurements. If the subject is required to maintain a certain angle between the arm and the torso, there may be swings or changes in posture, which will also lead to inaccurate measurement results. .
