Adjusting the coordinate to something other than the default
Hello everyone,
I know I can change the 0,0,0 location of a 3D object in 3-matic or some other software, but I am interested in changing the 0,0,0 location in the volume of slice images in Mimics.
I know that the Z coordinate comes from the scan's metadata and that X and Y get dropped to 0 upon importation.
Is there any way to manually adjust the 0,0,0 location of the volume to a point of my choosing?
I've thought about adjusting the table position of the dataset as I import it, but that doesn't help me with the default X and Y.
Any help would be appreciated!
Cristobal - good observation. In fact, the way Mimics addressed the patient coordinate system is something that has changed as of version 14. It now maintains all x,y,z coordinates from the DICOM header.
In case you need to keep coordinate systems consistent between Mimics 14 and older versions, there is an option to save a Mimics project to an older format. This will reassign the x,y position of the project. Going forward, though, the default coordinate system in Mimics will always be the true patient coordinate system.
Hi Jonathan,
This is something that currently cannot be done in Mimics. In Mimics 14.0, the coordinate system is read from the Dicom files and this cannot be altered upon importation. This may be a good suggestion to drop into the Idea Box on the Home page :).
As you mentioned, the coordinate system can be changed once you create a 3D object using 3-matic.

Hi
I read maybe some contradictory things in both posts:
Jonathan says "the Z coordinate comes from the scan's metadata and that X and Y get dropped to 0 upon importation", and Todd says "In Mimics 14.0, the coordinate system is read from the Dicom files and this cannot be altered upon importation"
What does actually Mimics do ??? Does it actually change the coordinate system ?? I'm asking it since I compared the a stl segmented outside Mimics, that is in the same system as the dicom (i verified it by hand), and it does not match with the images imported into mimics.
If I'm right, is there a way to keep the original dicom coordinates ?
Thanks in advance, best regards,
Cristobal.
