Predicting Nonalcoholic Fatty Liver Disease in Obese Populations with 3D Body Scans.

Nonalcoholic Fatty Liver Disease (NAFDL), characterized by the accumulation of fat in the liver, is considered a significant threat to public health, particularly in conjunction with obesity and the presence of Nonalcoholic Steatohepatitis (NASH). Traditional clinical methods for evaluating NAFDL, such as liver biopsy and MRI, are either invasive or costly. The utilization of 3D body scans offers a noninvasive and efficient approach to capture precise body shape information rapidly.

D3BT: Dynamic 3D Body Transformer for Body Fat Percentage Assessment.

3D body scan has been adopted for body composition assessment due to its ability to accurately capture body shape measurements. However, the complexity of mesh representation and the lack of fine-shape descriptors limit its applications in body fat percentage analysis. Most studies rely on algorithms applied to anthropometric values derived from 3D scans, such as multiple girth measurements, which fail to account for the body's detailed shape.
