Avensys and Eastwood Park, both excellent training providers,
I have two staff undertaking an apprenticeship with Avensys presently and one member of staff training at Eastwood Park. I will encourage all to progress to gaining a Biomedical Engineering Degree. The benefits to the individual and department are huge, well worth the investment.
I would advise any new department manager to establish training initiatives in their budget as a priority.
As for on line courses see https://www.e-lfh.org.uk/
Lots of clinical, non-clinical and mandatory training here, some good training on devices and some excellent IPEM radiation/imaging training.
