Using GetScalarType the type returned is short, i was using int. But the value maximum showed is 1024 and i see the maximum short value is 32767 and the intensity value is not corret.<br><br><div class="gmail_quote">2010/9/10 Jim Peterson <span dir="ltr"><<a href="mailto:jimcp@cox.net" target="_blank">jimcp@cox.net</a>></span><br>

I think GetScalarPointer returns an address of the scalar that still needs to be dereferenced according to the scalar type for the image.<br>
<br>
I googled - vtk getscalarpointer - and the class reference is pretty complete. you probably need to use GetScalarType to determine how to cast the pointer from GetScalarPointer to dereference the value.<br>

Hi,<br>
<br>
I want get DICOM image intensity of any point. I dont want MIP volume. I am using the code below for get the intensity, but the value is not correct:<br>
<br>
image->GetScalarPointer(image_coordinate);<br>
<br>
I see the correct value with software ITKsnap, i must use ITK for get correct intensity value?<br>
