Unable to See Phantom Model in fCal for Registration

[jonortega77]

Description: I am unable to view the phantom model in fCal, which prevents me from performing phantom registration to obtain the PhantomToReference transformation matrix. This limitation is difficulting me to complete the spatial calibration of the ultrasound.

Note! Stylus Calibration perform before trying the Phantom Registration.

Steps to Reproduce:

1. Launch fCal and connect to NDI Polaris Spectra
2. Navigate to the section for phantom registration.
3. Attempt to load or visualize the phantom model.

Expected Behavior: The phantom model should be visible along with the Stylus (visible) and accessible for registration, allowing me to obtain the necessary transformation matrix for spatial calibration.

Actual Behavior: The phantom model does not appear, and I am unable to proceed with the phantom registration process.

Screenshots:

Here is my XML config file:

`

<PlusOpenIGTLinkServer MaxNumberOfIgtlMessagesToSend="1" MaxTimeSpentWithProcessingMs="50" ListeningPort="18944" SendValidTransformsOnly="true" OutputChannelId="TrackerStream" >

<fCal PhantomModelId="PhantomModel" ReconstructedVolumeId="Volume" TransducerModelId="ProbeModel" StylusModelId="StylusModel" ImageDisplayableObjectId="LiveImage" NumberOfCalibrationImagesToAcquire="200" NumberOfValidationImagesToAcquire="100" NumberOfStylusCalibrationPointsToAcquire="200" RecordingIntervalMs="100" MaxTimeSpentWithProcessingMs="70" TemporalCalibrationDurationSec="10" FixedChannelId="VideoStream" FixedSourceId="Video" MovingChannelId="TrackerStream" MovingSourceId="ReferenceToTracker" DefaultSelectedChannelId="TrackedVideoStream" FreeHandStartupDelaySec="3" />

Image Reference

<vtkPhantomLinearObjectRegistrationAlgo PhantomCoordinateFrame="Phantom" ReferenceCoordinateFrame="Reference" StylusTipCoordinateFrame="StylusTip" />

`

Environment:

fCal Version: 2.9.0.0 Operating System: Windows 11

Additional Information: This issue is critical for my project as I need the PhantomToReference transformation matrix for spatial calibration of the ultrasound. Please let me know if there are any logs or additional information I can provide to assist in resolving this issue.

Note! The PhantomDefinition shown in the XML config file has been taken from another existing config file that also use fCal_2.0.stl phantom. ` <Description Name="fCAL" Type="Multi-N" Version="2.0" WiringVersion="2.0" Institution="Queen's University PerkLab" />

Any help would be appreciated !

Thanks,

Jon
