    % Creates a CUDA-based simple backprojection
    %
    % sinogramData: 2D matrix with projections stored row-based
    % theta: projection angles, length should be equal to the number of rows in
    % sinogramData
    % reconstructionSize: vector with length 2 with the row and column count of
    % the reconstruction image
    % backProj: 2D back projection from sinogram data
