when the DICOM image was in Axial view. I was able to display the<br>orientations from the DICOM file using the formulas provided in the<br><a href="http://www.dclunie.com/medical-image-faq/html/part2.html" target="_blank">http://www.dclunie.com/medical-image-faq/html/part2.html</a> site by Mr. Clunie.<br>
Using this i get the orientation of the image of that particular DICOM image<br>but how should i calculate the orientations for the other views except the<br>one present in the DICOM file when reconstructed using the VTK.<br>
<br></blockquote></div>Hi Abhistek;<br>If you are using vtkImageViewer2 for MPR rendering you can find their orientations like this:<br><br>First find all axial (XY plane) orientations for left, top, right , bottom, front and back sides of vtkImageViewer2 and insert them into an array or stringlist etc. and do these calculations for other views:<br>
<br>enum tagSCREEN<br>{<br>LEFT=0,<br>TOP,<br>RIGHT,<br>BOTTOM,<br>FRONT,<br>BACK<br>}ESCREEN;<br><br>//Sagittal<br>StringList getOrientationAnnotationForYZPlane()<br>{<br>StringList xy=getOrientationAnnotationForXYPlane();//axial orientations<br>
<br>StringList list;<br>list.insert(LEFT,<a href="http://xy.at/" target="_blank">xy.at</a>(TOP));<br>list.insert(TOP,<a href="http://xy.at/" target="_blank">xy.at</a>(BACK));<br>list.insert(RIGHT,<a href="http://xy.at/" target="_blank">xy.at</a>(BOTTOM));<br>
list.insert(BOTTOM,<a href="http://xy.at/" target="_blank">xy.at</a>(FRONT));<br>list.insert(FRONT,<a href="http://xy.at/" target="_blank">xy.at</a>(LEFT));<br>list.insert(BACK,<a href="http://xy.at/" target="_blank">xy.at</a>(RIGHT));<br>
return list;<br>}<br>//Coronal<br>StringList getOrientationAnnotationForXZPlane()<br>{<br>StringList xy=getOrientationAnnotationForXYPlane();//axial orientations<br><br>StringList list;<br>list.insert(LEFT,<a href="http://xy.at/" target="_blank">xy.at</a>(LEFT));<br>

</font></blockquote></div><br></blockquote></div></div>Just create an instance of vtkImageViewer2 and set its renderwindow and interactors, then set the viewer->SetSliceOrientation(int orientation); according to your mpr rendering...for axial rendering orientation should be 2, sagittal=0, coronal =1;<br>
<br>But of course if you have already implement the mpr rendering using vtkImageTransform and vtkImageReslice you can set the stringlists according to your transforms...The ones that i send are for vtkImageViewer2's transforms, you can just control the values if they are true, if not you can modify them for your transforms.The ones that i send were only examples for giving the logic of orientation...<br>
