Hi Jim,<br><br>I have dicom image with teeth, i am looking intensity values of 2 front teeth. <br><br>But some happen very strange, the tooth the left have <span id="result_box" class="short_text"><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);" title="">greater intensity </span></span>in ITKsnap 2518 and my code -1024. The tooth the right side have in ITKsnap 2402 and in my code 41. <span id="result_box" class="short_text"><span style="background-color: rgb(255, 255, 255); color: rgb(0, 0, 0);" title="">I do not know why the values are different.</span></span><br>
<br>In my code i get 255 points of heigh and width, but when i get dimension the image, vtk show 512 x 512, same dimesion show in ITKsnap. ITKsnap get dimension of voxels, so i must get information the intensity value voxel of volume and no pixel the image?<br>
<br>thanks.<br><br><div class="gmail_quote">2010/9/11 Jim Peterson <span dir="ltr"><<a href="mailto:jimcp@cox.net">jimcp@cox.net</a>></span><br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Personally, I am sorry, but there is not enough information in your description of the problem to be sure you have a legitimate complaint. does your dicom data consist of only one point? how are you certain you have selected the exact same location?<br>
<br>
in my mainframe programming life we have a saying:<br>
<br>
"when expected results do not match observed results, check the library concatenation"<br>
<br>
.... in my opinion, chances are you are looking at different points.<br>
<br>
sorry, Hoping to be helpful not critical.<br>

I am expecting MIP of image point. In my program the value for one<br>
point is 1023 and ITKsnap show 2210.<br>
<br>
Why the value is different?<br>

<br>
Depending on how you read the dicom file the value should be in<br>
hounsfield units. I am confused on whether you mean you were<br>
expecting<br>
32767 or hounsfield.<br>
