GENtrace

An initiative from GE Healthcare to develop their yet smallest cyclotron for PET scanning


What is a cyclotron?

Simply a particle accelerator used in nuclear medicine, explanied in this short video:


My Contribution

As a consultant at Prevas AB, I was contracted by GE Healthcare 2013-2015

My mission was to develop a new Side cabinet for the GENtrace cyclotron containing a Radio Frequency Unit, a Water Cooling Unit, and the rest of the control units needed for the cyclotron

Radio Frequency Unit

An alternating high voltage device, creating an oscillating electric field that accelerates particles. For this module I worked closely with GE electrical team.

  • Designed with aluminum sheet metal and complex welding solutions
  • CFD modeling for air cooling
  • FE Analysis on door due to usage of Gaskets for enhanced EMC shielding

Water Cooling Unit

Alternating high voltage means a lot of friction and hence the need of much cooling. The Water Cooling Unit is placed inside the Cabinet as a full servicable drawer and is connected by hoses to the back side of the cyclotron (pic) for further distribution. This unit was designed in cooperation with GE advanced engineering team.

  • Designed for best possible servicability
  • Solutions for leakage and condensation issues

Side cabinet and Flexible positioning solution

This cabinet managed to be both Lighter, Smaller and Cheaper than its previous model (PETtrace). Reasons behind this accomplishment was the reduction of one of the main control units, much design with sheet aluminum + FE Analysis, and negotiation with new suppliers. On top, this cabinet is equipped with a telescopic cable- and hose canal, adjustable in 180° for maximum cabinet position flexibility for different hospital spaces.

  • Low weight cabinet
  • Good servicability in tight spaces
  • Good position flexibility vs Cyclotron
