Length tool in modalities CT, DX, MG show the units in pixels

[christianvargasforero]

I have been testing the length tool in different modalities and I see that only in CT shows the units in mm. The tests were done on the most recent version of the viewer and the configuration used is that of dcm4cheeDIMSE.

In the DX, CR, MG modes, the tool displays the units in pixels.

I send the samples so they can try.

DX --> Units in pixels.

It work on DX and MG of latest version (unit is mm).
However, XA is still displayed in pixel of unit.

XA --> Unit in pixels.

Hi Christian Vargas,
Can you please help me out to get the fixed code of this thread, Still the measurement tool showing in pixels for MG and DX modalities with the latest git version of the viewer code.

This happens if the DICOM does not have a pixelSpacing tag. We need it to convert pixel length to mm.
