Nuclear Medicine
Nuclear medicine is a branch of medical imaging that uses small amounts of radioactive material to diagnose and determine the severity of treat or a variety of diseases.
Nuclear Medicine – PET/CT camera
PET/CT camera QA Test
QA testing of PET camera
The Nuclear Medicine Accreditation Committee Standards
PET Phantom
Phantom image
QA testing of PET camera
Testing Result:
Image including calculated
values such as:minValuemaxValueMeanRatios
The goal
The project goal is to automate PET/SPECT cameras QA procedure in order to reduce time.
Possible Problems
Bad slice: Good slice:
Our application
Application does the following steps:
• Define template (mask).• Choose the “best” slice.• Fit the template to the PET image slice.• Calculate values and generate report.
Find the “best” sliceProblem: Choose “best” slice from all slices, given by the camera
Solution: Walk through all PET Dicom images, adjust contrasts (leave only HOT rods) and find circles using HOUGH algorithm.
Template definition
Problem: Find ROIs on Best PET slice.
Solution: Apply the PHANTOM MASK on the Best PET slice to get ROIs.
Fit the MASK
Problem: Fit the PHANTOM MASK to the PET image slice.
Solution: Scale the MASK and apply (move/rotate) on the image.

Testing
• GUI Testing.
• QA Test results testing (comparing received results from the system with the test result made by physicians).
Final Conclusions
• In a work with image processing, you need to pay attention that the image processing result generally are not accurate, and if there is a need in precision you need to try additional techniques in order to double check your results.
• If there are similar images but with different quality you need to adjust the contrast in order to improve your image.
• Our work was based only on two kinds of GE cameras, so the project is oriented for them. Any additions may cause additional changes in algorithms and calculations.
