12/26/2023 0 Comments Apex dead space lungJaccard similarity coefficients and Dice coefficients have been used to find accuracy of the modeled shape through comparison with the prepared ground truth. Local, piecewise polynomial interpolation is then employed to create additional semilandmark points to form the lung contour. Selected radiographs are anatomically landmarked using 17 and 16 anatomical landmark points to represent left and right lung field regions, respectively. Japanese Society of Radiological Technology (JSRT) database which is publicly available has been used for evaluation of the proposed method. In this paper, a landmark based approach, using five different interpolating polynomials (linear, cubic convolution, cubic spline, PCHIP, and Makima) for modeling of lung field region in 2D chest X-ray images have been presented.
