| The presented work proposes a mathematical model that describes polyps as stomach illnesses. It presents a practical application of the proposed model to measure polyp sizes. A method for determining polyp sizes on the basis of characteristic points plotted over the obtained video material has been also proposed. Authors proposed to use two coordinates system for describe of share: the spheroidal coordinates (prolate and oblate) (η, θ, ψ) or the parabolic coordinates (μ, υ, ψ). The first coordinates system describe shares from spherical to segment. The second coordinates system describe figures from oblate spheroidal to spherical. |
