Targets have wide use in medical cyclotrons, a type of particle accelerator used in nuclear medicine to produce radiotracers. These are used in Positron Emission Tomography (PET) scans as drugs to detect abnormal metabolic activity in tissue and organs.
The target is where the production of radionuclides takes place and it is installed in one exit port of the cyclotron where accelerated sub-particle are deviated to irradiate the solution inside the target.
Target Multi-purpose: NHC-X Gen II Liquid Target
To obtain radionuclides, NHC-X Gen II targets produced by AMMO Imaging are made of different parts leading to different purposes/scopes to optimize the performance of the production.
NHC-X target has a good design insert to enhance the cooling of the windows and insert and doesn’t need helium cooling utilities as a medium to cool down the windows like most commonly used targets.
It is important to cool down the vessel of reaction and a very important factor in No-Helium Cooling targets is the heat transfer coefficient from the water cooling side to the solution target side.
The design of the target guaranteed a high yield of production (up to 250mci/µA sat) in the entire operative range of irradiating current: from 50µA/h to 120µA/h for typical production of 18-F.
NHC-X Gen II targets are assembled and designed to prevent and reduce maintenance downtime; thanks to the design of the target, transfer lines are directly connected to the insert, without using an O-ring that can be damaged over time.
Preventive maintenances are done after 15000µA life target or after 3 months.
NHC-X targets do have not He-cooling utilities, leading to fewer materials that are activated by the electron beam. Thus, reducing waste and dangerous material to be discharged and less radio exposure to the technician during maintenance.
Furthermore, the simplified mounting/dismounting operating procedure makes the target easy to mount/dismount reducing exposure to ionizing radiation.
