PET Detects gamma rays Interact with the crystals and release photons Smaller the crystal, the less uncertainty

THE PROJECT TOFPET Time of flight (TOF) Positron emission tomography (PET) ClearPEM The Crystal Clear Collaboration’s positron emission tomograph for mammography (PEM)

TOFPET PET uses medical photon detectors New crystals coupled to photodetectors can reach coincidence time resolutions below 500 ps Improvement of imaging signal to noise ratio is achieved with time resolution on the order of 500 ps Exact localization of positron emission point

CLEARPEM Breast Cancer X-ray, mammography, MRI lack specificity whole-body PET lacks resolution Improves diagnosis Metabolic information from PEM Exact position of cancerous lesions Localizes the lesion in the surrounding tissue

CLEARPEM 3D images First Clinical Trail Detects more cancerous lesions than whole-body PET Contributes to an increase of the specificity in the diagnostic process

CLEARPEM DESIGN Horizontal patient bed Hole for the breast Two parallel detector plates that revolve around the breast to register a 3D PET image

2 PLATES 192 matrices 4X8 192 X 4 X 8 = 6144 crystals

MY PROJECT ClearPEM boards (2) Arriving this week Measuring matrices at their breakdown voltage 256 matrices  1 detector for 4 crystals Took about 1 month to glue photodetectors on each matrix (10 per day) Test with gamma source to make sure glue didn’t damage Usually fine

TESTING MATRICES Used Cs-137 Spent some time accurately lining up the placement of the matrix, the source, ect. Set breakdown voltage (information given when glued) Current between 15 and 25 microamps Run program, record data, plot values

LAST WEEK AND THIS WEEK Data comes in for each photodetector Histograms of how many photons interact with each crystal What percentage of one is in the other?

CONCLUSION Process of building the external plate Characterization of crystals Test photodetectors Glue the two Test crystals after gluing Create external plate See medical images by the end of June
