create a 3D view from a 2D section

hello everybody. I have 2D image are the measure of diameter of a pipe, this measure is carried out are of a variable distance, how I can build a 3D view from these 2D sections respecting the height, and especially the rotation thereof following the xy plane? I add my code thank you all

    %
clear all
close all
M=importdata('Scanner.txt'); 
[R,C] = find(M>0);
Ma=max(R);
for i=1:Ma
    V=find(R==i);
    x=(C(V))';
    y=M(i,x);
    %élimination des points abérants
    MEDIAN=mean(y);
    I=find(y>MEDIAN-10 & y<MEDIAN+10);
    xcalcul=x(I);ycalcul=y(I);
    [Xcalcul,Ycalcul] = pol2cart(xcalcul/1800*pi,ycalcul);
    [X,Y] = pol2cart(x/1800*pi,y);
    MAT(i) = fit_ellipse( Xcalcul,Ycalcul,gca);
end

and i use fit_ellipse fonction to create my 2D image
