Establishing a good algorithm for predicting body fat of body composition is an important issue. In this study, a novel body fat prediction method by using Choquet integral regression model based on L-measure and Gamma-support is proposed. For evaluating the performance of this new algorithm, a 5-fold Cross-Validation RMSE is performed. Experimental result shows that this new prediction scheme is...
Accurate estimation of body muscle, fat and fluid volumes in dialysis patients is an important factor to predict outcomes of the disease. Bioimpedance spectroscopy (BIS) has been used to measure extracellular (Re) and intracellular resistance (Ri) with whole body (wBIS) and segmental (sBIS) measurement. 40 stable HD patients (22 m / 18 f, age 54.7 plusmn11 yrs, height (H) 1.67 plusmn 0.94 m, weight...
This study aims to determine the body density using the hydrostatic weighing method as a standard and comparison of results obtained with the dynamometer and a microcontroller-based system using the load cell. We used a population sample of 78 male subjects, between 18 and 35 years of age and were 7 to 10 measurements of the hydrostatic weighing for each. Through the SPSS software was analyzed information...
Single frequency bioelectrical impedance analysis (BIA) is an inexpensive, quick and painless means of estimating body composition. In this paper, BIA parameters employed for predicting hemoglobin (Hb) in dengue patients. The BIA technique passes a low-amplitude electrical current, in the range of 500 muA to 800 muA, at a single frequency of 50 kHz. BIA data was sampled from 210 (comprises of 119...
In vivo assessment of human body composition quantities from imaging/scanning systems in clinical research and public health has led to proliferation of indirect methods and techniques that deliver approximating values. The systems are based on morphological or biochemical models and assumptions. Since the development of dual-energy X-ray absorptiometry (DXA) for the bone density, mineral content...
This paper proposes a compensation for a blurred image caused by misregistration in spatial compounding. The edge sharpening based on morphological operations is applied to the compounded image. A portable measuring system of a cross-sectional ultrasound image is designed for measuring body composition. The system is developed for non-medical applications, for example, measurement of the volume of...
Bioelectrical Impedance Spectroscopy (BIS) is a noninvasive technology with potential application to study exercise physiology as body composition and estimation of maximal oxygen uptake. The aim of the study was to compare the power at lactate threshold (WLT) obtained using blood lactate concentration (BLC) with the power at lactate threshold from BIS (WBT). Fifty physical education students, 35...
Bioelectrical impedance analysis (BIA) has been proven an inexpensive, reliable, simple, safe, and noninvasive technique for clinical and non clinical purposes. The ability of BIA to accurately assess body composition is dependent upon a number of technical and biological assumptions. This paper provides an overview of the strengths and weaknesses of the BIA method with specific reference to assessment...
MRI and image quantitation play an expanding role in modern drug research, because MRI offers high resolution and non-invasive ability, and provides excellent soft tissue contrast. Moreover, with development of effective image segmentation and analysis methods, in-vivo and serial tissue growth measurements could be assessed. In the study, MR image acquisition and analysis protocol were established...
