Magnet positioning error

This site near Buffalo, New York required a special room with a "high-hat" design to allow enough clearance for the current probe. Additionally, the soil conditions were such that the site required four pilings to be sunk to hold the weight of the magnet.

Since these pilings were to be drilled and installed inside an existing building, a special rig was assembled in the space at considerable time and expense.

All the while this work was underway, the magnet, an Oxford OR30, sat outside in the parking lot.

A group of people, including the MRI owner's engineer and the general contractor measured and marked "iso-center" in the room. The contractor proceeded to drill and place the pilings and then build up the scan room. And he never checked the measurements.

Here's the result after the magnet was placed on the pilings.

The rear of the magnet (1) is 40 inches further into the room than the rear of the high-hat area (2).

The front of the magnet is so far past the front edge of the high-hat (2) that there is not enough vertical clearance to install the current probe (1).

This view from the other side of the magnet shows how the forward turret (1) is past the front-edge of the high-hat (2).

The magnet had to be removed from the room. The room was partially disassembled and new pilings were drilled and placed. All of this because no one checked the measurements - and the magnet was right outside the building in the parking lot. The result - a two month, $60,000+ delay in the installation.

This is the same magnet - two months later. It's now in the correct position.
