However, most power units are driven by motors that are either not MRI-compatible or require external connections that restrict mobility and usage. In this paper, the development of a highly portable, lightweight, and MRI-compatible pump system is explained.Methods: The energy required to deliver the flow is generated using a pressurized bottle concept. The valve inside the bottle is opened to create a flow which should be maintained constant. In order to find the optimal flow resistance for a constant flow rate, we created multiple setups with different flow resistance.Results: We measured the flow rates for different flow resistances by attaching a restring valve to the bottle. The results clearly show that high flow resistance results in lower and more constant flow rate.Discussion: The optimal flow rate achieved using our current setup was significantly constant but not ideal. Consequently, such a pump system can be used in many medical applications like MRI-compatible contrast agent injectors.Keywords: MRI-compatible, pump system, pressure, fluid, constant flowrate, injection, infusionKalmar MBoese ALandes RFriebe MDove Medical Pressarticlemri-compatiblepump systempressurefluidconstant flowrateinjectioninfusionMedical technologyR855-855.5ENMedical Devices: Evidence and Research, Vol Volume 12, Pp 469-478 (2019)
