<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>I have tried to read
multi-frames DICOM file by using vtkGDCMReader.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>I found
vtkGDCMReader will allocate one huge block memory to load image
PixelData from file </SPAN></FONT><FONT face=Arial size=2><SPAN
class=984470700-12122006>and another block of memory of the
</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>same
size for destination(for flipping in y-direction). This approach will
cause the peak memory size is very high</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>because it will
allocate two huge block memory during executing. </SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=984470700-12122006></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>For examples, if the
imageData File's size is 170M, the peak memory size will hit
340M.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=984470700-12122006></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>Is there any
possible to read just one slice pixelData from file instead of reading
all?</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=984470700-12122006>So we can do data
streaming to avoid the high peak memory size.</SPAN></FONT></DIV>
