San Diego Specialist in Biomagnetic Technologies Shuts Down

San Diego-based 4-D Neuroimaging, a small company that specializes in magnetoencephelography, or MEG, to detect bio-electric fields in the brain and other organs, has abruptly ceased operations.

A letter posted on the company’s web site explains 4-D Neuroimaging could not secure additional financing it needed to continue operations. Our updated San Diego layoff tracker is here. The company, which reportedly had 38 employees, supplied an advanced diagnostic machine, the Magnes 2500 WH, to hospitals around the world. Equipped with dime-sized superconducting sensors, the machine has been used primarily to pinpoint the site of neural electrical storms in patients diagnosed with focal epilepsy.

“I loved my job at 4-D, there was a wonderful group of people there,” said Rick Orr, who was an employee until he was instructed to clean out his desk Monday. He declined further comment.

“It’s a shame, it’s a good technology,” said Bob Fagaly, a onetime employee and expert in sensing technologies. “The people who started it came out of UCSD.”

The Feb. 16 letter on the company’s web site is addressed to 4-D’s customers, and is signed by CEO Scott Buchanan and board chairman Martin Egli. “Despite all the advancements of MEG as a technology,” it says, “the entire MEG industry has required continuing financial investments to offset its continuing losses. With the recent economic downturn, sustaining this type of investment has become increasingly difficult.”
