Medical Image Reconstruction

First images have been produced by JPET Controller board!

The controller processes data streams from 8 TRBs, parses the TDC data and recovers hits on scintillators. The hits are correlated together by scanning with a time window and then mapped into the detector geometry in order to recover LOR coordinates. Finally instead of raw TDC data only two points from LOR are being sent.

JPET Controller power up!

After several ups and downs we have successfully evaluated all the key elements of the JPET Controller and the hardware is ready to use!

In just short time several test projects have been run, including mainly:

  • IBERT (Integrated Bit Error RatioTester) on all the 16x optical links
  • ZYNQ Processing Systems with DDR3 and UART-USB
  • Gigabit Ethernet Module on all the 16x optical links

Now everything is ready to start implementing tomographic data processing!

JPET DAQ System up and running

A large FPGA-based Data Acquisition Systems for JPET tomograph prototype is up and running!

The system consists of 9x TRBv3 modules running in 1x Master – 8x Slaves mode, collecting data from 384 photomultipliers, delivering signals to 1536 high-resolution TDC channels.

Generated data stream is forwarded into 3x 1Gb network interfaces of a server class rack computer. We are awaiting for the founds dedicated to network upgrade to 10Gb solutions.

Great hardware and software solutions allow to display data quality histograms constructed in the real time as well as storing data for further offline processing.
