I want to use MRI clinical scanner for research purpose (Philips type), but most of the MRI clinical does not have EPI sequence for doing fMRI experiments, is that possible and how much it cost to install to the scanner,
Any information it will help.
Thanks
Philips does have a product EPI sequence. If your scanner does not have EPI, I can think of a couple of possible reasons.
Maybe you need a license (I am not sure since I am not a Philips user) that your site chose not to purchase, in which case you need to talk with your Philips sales representative.
The other possibility is that your scanner is not designed for EPI. EPI is a very demanding pulse sequence that causes a lot of mechanical stress on the system. I would imagine that open-MRI systems or portable MRI systems, would not handle these stresses well. Even if those scanners could run EPI without damaging the system, the image quality would likely be very poor. I have heard that some vendors don't put EPI on portable MRI scanners for this reason.
