此函數(shù)用于交互式查看任何類型的2D、3D和4D圖像，如CT和MRI。

This function can be used to interactively view any kind of 2D,3D and 4D image volumes like CT and MRI.

允許在二維切片中進(jìn)行分割、距離測(cè)量或ROI選擇。

Allowing segmentation and distance measurements or ROI selection in 2D slices.

包括最大強(qiáng)度投影（MIP）、體渲染（VR）、切片渲染以及著色和Phong陰影的體渲染。

It includes Maximum intensity projections (MIP), Volume Rendering (VR) , Slice render, and colored and Phong shaded Volume rendering.

體素不透明度和顏色表可以隨時(shí)更改，也允許ISO表面類型的渲染。

Voxel opacity and color tables can be changed on the fly allowing also iso surface kind of renders.

快速渲染算法將三維體渲染為二維圖像，該算法基于剪切扭曲變換的Matlab實(shí)現(xiàn)，采用了剪切切片而不是旋轉(zhuǎn)觀察射線。

The fast render algorithm which renders a 3D volume to a 2D image, is based on a Matlab coded implementation of the Shear-Warp transform, in which instead of rotating the viewer rays the slices are sheared.

兩個(gè)主要的Matlab文件為：

viewer3d.m : GUI交互界面

通過(guò)剪切扭曲轉(zhuǎn)換將體數(shù)據(jù)渲染為二維圖像的函數(shù)

There are two major Matlab files:

• viewer3d.m : The interactive GUI

• render.m : The function which renders volume data with the shear-warp transform to an 2D image.

本函數(shù)支持的文件格式包括：

Matlab Files (.mat)
Dicom Files ( .dcm , .dicom )
V3D Philips Scanner ( .v3d )
GIPL Guys Image Processing Lab ( .gipl )
HDR/IMG Analyze ( .hdr )
ISI Files ( .isi )
NifTi ( .nii )
RAW files ( .raw , .* )
VMP BrainVoyager ( .vmp )
XIF HDllab/ATL ultrasound ( .xif )
