a stereotactic frame for small primate imaging. This was used in a 9.4/210 Varian system. The gradient bore was 120mm.
Note: Ear bars are not in the rendering

A device I made that was used to exercise a calf muscle while in a MRI for spectroscopy . It was bolted to a customized bed top. The S device is a load cell to measure force which could be seen by the subject while being scanned. Mostly made from 0.5" polycarbonate

A render of a device I designed and built. Used in a small MRI system. It holds an ultrasound transducer (HIFU) that could be moved in 2 planes. Built from acrylic and fiberglass.
Modeling done in SolidWorks

This is a few years ago, a Philips 3T about to be removed. The walls are partially removed as the whole RF room was being replaced by Imedco. The room was 10+ years old and was developing RF leaks

Some photos of device to make hyperpolarized hydrogen I helped design and fabricated all the parts.
here is a link to the paper that it was used in.
