Recently retired from Siemens-Healthcare, I fixed/maintained MRI's, ultrasound, and nuclear medicine systems in hospitals and doctors office as a customer service engineer. I started with Wang Labs in the early 80's and was laid off (best thing that ever happened to me) in the early 90's working the financial district in SF. The first decent job was fixing Wang equipment third party for the state of Hawaii, did that for 1 year and found a job with a small ultrasound company (2K employees) Acuson. 9 years later Acuson was bought by Siemens (340 million employees at the time 495 million). It was a good 40 year career.
