Opening a DICOM file in InVivoDental


In this tutorial we will go over loading a DICOM volumetric data set in InVivoDental and see how to  access the DICOM header information included in the CBCT data set.

You can load a DICOM file by going to File>Open.

Opening a DICOM data set

Starting with version 4 of InVivoDental, you now have a window showing the recent files you have opened previously. At first glance, one might think this window can be used to connect to a DICOM server or a network drive but think again as that’s not the case. You can also see that one of the directories listed points to Documents (In Widnows XP it will be My Documents) > Anatomage Cases. You can double click on the items in the list to quickly open them. I don’t understand why Anatomage decided to make opening a file a two step process instead of one which was the case before in previous versions. Anatomage should have added the Open Recent option to the file menu instead.


If you click on Browse you will be able to go and select the DICOM data set that you want to load. InVivoDental can load different Anatomage file formats + .dcm (DICOM file). However, in this case we don’t see our data set. The reason for that is because some manufacturers decided not to include the .dcm extension at the end of their DICOM data set  files when their software exports the volumetric data set.

No DICOM files can be seen

From the drop down menu select All Files (*.*). Now you should be able to see a long list of files with bunch of letters and numbers. Select the first file and click Open. InVivoDental will scan the DICOM data set folder and then read the files.

After the reading process is done, you will  be presented with this screen.

The first thing you want to do if you are loading a data set from a colleague or an imaging center is to check the scan parameters like: CBCT scanner, FOV, Patient information, image dimensions. This can get you useful information before you start working with the data set.

Go to File>Case Info

Depending on your data set, some fields might be anonymized. This is important for HIPPA compliance in the US. The information included in the Case info is part of the information stored in the DICOM header file.

If you are unfamiliar with different DICOM header fields you can skip them. We can see in the picture above the patient data of birth study date,  the data set is from Xoran Technologies (i-CAT).

If you scroll drown you will see additional information: The rows and columns indicate the matrix size (resolution) which is 400 x 400 pixels per slice. The slice thickness is set to 0.4 mm and the image bit depth is 16 bits. Window width and center determine our brightness and contrast.
