Abstract: A method of selecting a stent for placing in an occluded segment of a blood vessel is presented. The method uses a diastolic and a systolic image of the blood vessel. In the method a first area is selected in a region on the diastolic image. The first area includes at least the occluded segment.

A stress in the occluded segment is determined by comparing the first length and the second length. Finally, the stent based on the stress in the occluded segment is selected.

Abstract: In a method for operating a three-phase inverter of a converter-fed magnetic bearing, two coils are connected to respective outputs of the three-phase inverter at one end and are connected to each other and to a third output of the three-phase inverter at the other end. A variable control current is injected into the third output. A constant bias current flows between the respective outputs and thus serially through the two coils. The control current is divided among the two respective outputs so as to flow parallel through the two coils. This arrangement significantly reduces the effective current load of the three-phase inverter and significantly increases the slew rate of the control current.
