X-Ray system is failing

Albira Report Visit  
from   "Report Visit Jan2018.Rev01.docx"

University of Virginia (UVA).
Charlottesville, Virginia State, USA.
SN: 0900125

Before of the visit
We planned visit the customer of the University of Virginia (UVA) to perform some different tasks what I describe in this list:
• CT Hardware reparation
• Installation of High Energy collimator
• Installation of the High-Resolution Collimator
• Installation of the 4 Mouse beds
• Installation of the Heater
The status of the Albira before this visit is:
• SPECT and PET are working at 100%.
• CT hardware is not working properly, the reason was in the X-ray detector hardware.
The technical service that will perform the visit is Rex Hurley and Emilio Gimenez.
Contact details: Stuart Berr PhD, email:
Address of the installation:
• University of Virginia /P.O. Box 801332 / 480  Ray C Hunt Drive

• 157 Snyder Building ; Charlottesville, VA 22903

Planning of the visit 
This was the original plan of visit:

Week 4 of 2018

And during the visit we must to prepare a second week plan of work, modifying some dates of work.

Explanation of the reparation about CT
The CT hardware presented a problem detected by the customer in the final of December of 2017, the issue was in the image of visualization, that is completely black and in the final of the acquisition the reconstruction obtained a black image too.
With this situation, it was necessary an onsite visit to check the hardware x Ray detector. For our experience in the past with other Albira we are going to focus of the issue in 2 points: Data hardware cable/power cable and electronic board frame grabber.
 Finally, the components that we have substituted in these two visits, it has been these:
• First visit:
o Data cable from flat panel x ray to the frame grabber.
o Electronic Frame grabber.
• Second visit:
o X-Ray Flat panel detector.
o Electronic Frame grabber.

o Power cable for the X-Ray Flat panel detector.

Summarize of the visit per days
We present the summarize of tasks per week, that way we may follow the main points done during our visit.

We present the summarize of tasks per week, that way we may follow the main points done during our visit.

Week 4	Thursday 25th to Monday 29th of January
CT reparation and Checks, final reparation. CT Geometry calibration and HU calibration QC for CT. PET-CT fusion QC PET SPECT-CT fusions PH and MPH SPECT-CT Fusion HEC and HResC

Images of the Second week:

CT Geometry phantom

CT Reconstruction High Res 40u

PET-CT fusion

SPECT-CT Fusion FVO 80 PH

SPECT-CT Fusion FOV 80 HEC

Quality control test (QC)

QC CT
Acquisition done 26th of January CT Best HV HD

QC PET 
Acquisition done 26th of January PET 20 min

QC SPECT
Acquisition done 19th of January SPECT 30 min PH FOV 120

Final revision
• After the CT reparation the customer did some acquisitions the 29th of January, what confirm the validation of the CT.
• We install the 4 Mouse bed and heater.
• Installation and calibration of the 2 new collimators HEC and HResC, in both case we calibrated the fusion with CT.
• Test with customer onsite with animals.

Subject: RE: Visit UVA 2º Week

Hello Prof Berr,

Yes I watched this morning

In any case, I have changed my flights to be in UVA next Thursday 26/Jan at 16-17:00H, I cannot be before onsite.

I will be in the lab the final of the day Thursday, Friday, and a half of Monday 29/Jan.

Is it possible work in the lab Saturday 27/Jan? In case that it was necessary to leave everything ready for the Studies of Monday.

Tomorrow, I will send you my plan of work with more details.

Thanks

Subject: Visit UVA 2º Week

Dear Prof Berr,

During the last Friday and Monday we have prepare the material to continue with the CT reparation.

Checking the tracking number of FEDEX(Tracking: 689849861236), with any delay we will have components on site Wednesday 24/Jan.

I will be in charge of do this reparation, actually I am in Mexico and I need to coordinate the tickets plane to know exactly when I will arrive to UVA.

My plan is visit you Thursday to do the reparations and to be there Friday, Saturday probably to be sure that everything goes correctly.

As soon as I have my planning ready, I will share with you.

Have a good day!

NOTE FROM SSB - 1/19/2018

After replacing a number of cables, the CT would run for a while and then flake out. It was determined that the flat panel Hamamatsu detector is bad. A new one was ordered and should be here by Wed. 1/24/2018. Rex and Emilio left but will return when the detector is here. 

ssb 1/20/2018

NOTE FROM SSB - 1/16/2018
Rex and Emilio determined that a connector on a cable on the CT detector was not making proper contact as one of the screws that fastens the connector could not be screwed in. The replaced the entire cable and things worked fine.

Emilio and I are flying in on Sunday Jan 14, he will be there one week I will be there two weeks, we need to know what isotopes that you want the HEC's calibrated to, so we can make the schedule__ ____________________________________

Hi Rex,

When are you planning to show in Charlottesville. I thought we had set a time, but cannot find the info. Sooner is better. Thanks.

Subject: RE: Tomorrow morning

Dear Stuart,

Excuse me but I do not have good news about the issue detected with the network and with the CT.

This morning I did a revision in the scanner looking for the problem with the network connection and after your email testing CT too.

And I discovered that the CT hardware has a problem and it does not allow carry on a normal acquisition. (See the image in black during the acquisition) I tried to do some acquisitions with the CT and I cannot do it, but the PET and SPECT runs normally.

After this point we are going to prepare a set of components to repair the problem with the CT, and next Tuesday I am going to prepare the shipment to have the material asap in UVA.

Rex will contact with you to prepare the visit.

Sorry to report this problem and I hope that we can solve soon.

Best regards,

Subject: RE: Connection to M: drive

Hello Stuart,

This morning I was looking the CT images to understand what it was strange in the acquisition of yesterday.

After review the projections(I attached a video with the projections), I think that probably we have got an interference connection in the data cable of the flat panel. We add this point to review during our visit in January.

The Geometry is not affected during the acquisition and for this reason the images are ok.

Please, contact with us in case that you have any doubt or suggestion.

Thanks,

Hi all,
  there appears to be streaking in the X-Ray projections. It seems to not be there in the reconstructed images. Do you have an idea what is causing this? 
   Everything else seems to be working well. 
   Thanks

Stuart
