沿2维图像片段插 [英] Interpolating along the 2-D image slices

问题描述

我有一组的 100 2-D图像相同大小的切片。我已经使用MATLAB来堆放它们创建一个体数据。而二维切片的尺寸为480x488像素，其中，所述图像被堆叠不够宽时投影到可视化的容积在不同取向方向。我需要沿着片插值来增加可视化的大小。

I have a set of 100 2-D image slices of the same size. I have used MATLAB to stack them to create a volumetric data. While the size of the 2-D slices is 480x488 pixels, the direction in which the images are stacked is not wide enough to visualize the volume in different orientation when projected. I need to interpolate along the slices to increase the size for visualization.

有人可以请给我一个想法或提示如何做到这一点？

Can somebody please give me an idea or tip about how to do it?

编辑：Anotated投影显微镜，图像

Anotated projected microscopy-images

图1是顶视图，图投影体积的

The figure 1 is the top-view of the projected volume.

图2是侧视投影体积的

当我改变旋转角度，并尝试可视化不同的方向，例如音量侧视（图2），是我看到如在图2

When I change the rotation-angle, and try to visualize the volume in different orientation, e.g. side-view (figure 2), is what I see as in figure 2.

欲通过沿着图像切片内插，扩大侧视图。

I want to expand the side view by interpolating along the image slices.

推荐答案

下面是从的如何可视化的体积数据（类似于你）MATLAB文档使用等值面的：

%# load MRI dataset: 27 slices of 128x128 images
load mri
D = squeeze(D);       %# 27 2D-images

%# view slices as countours
contourslice(D,[],[],1:size(D,3))
colormap(map), view(3), axis tight

%# apply isosurface
figure
%#D = smooth3(D);
p = patch( isosurface(D,5) );
isonormals(D, p);
set(p, 'FaceColor',[1,.75,.65], 'EdgeColor','none')
daspect([1 1 .5]), view(3), axis tight, axis vis3d
camlight, lighting gouraud

%# add isocaps
patch(isocaps(D,5), 'FaceColor','interp', 'EdgeColor','none');
colormap(map)
