Abstract
A device for estimating breast implant volume is provided, which may include an input interface and a processing circuit. A numerical value may be inputted in to the input interface. The processing circuit may calculate the estimation value of breast implant volume according to a linear model and the numerical value. The processing circuit may multiply the numerical value by a coefficient to generate a product, and add a constant to the product to generate the estimation value of breast implant volume, wherein the numerical value may be a breast sample weight or a breast size.
