TRANSFORMER FOR A COMPUTER TOMOGRAPHY GANTRY

摘要

The invention provides a transformer for a computer tomography gantry (91) for transfering contactlessly electrical energy from a stationarypart ofthe gantry (92) to a rotary part of the gantry (93), wherein the transformer comprises a set of primary windings (103, 105, 203, 204), a set of secondary windings (103, 105, 203, 204), a set of first cores (101, 202, 301), a set of second cores (101, 202, 301), wherein the set of primary windings (103, 105, 203, 204) being arranged at the set of first cores (101, 202, 301) on the stationary part of the gantry (92), such that a winding of the set of primary windings (103, 105, 203, 204) is adapted to induce a magnetic flux into a core of the set of first cores (101, 202, 301), wherein the set of secondary windings (103, 105, 203, 204) being arranged at the set of second cores (101, 202, 301) on the rotary part of the gantry (93), such that a winding of the set of secondarywindings (103, 105, 203, 204) is adapted to induce a magnetic flux into a core of the set of second cores (101, 202, 301), wherein the set of first cores (101, 202, 301) and the set of second cores (101, 202, 301) are adapted to reduce mechanical resonant vibrations caused by the rotation of the rotary part of the gantry (93). Another aspect of the invention is a computer tomography gantry (91) comprising a transformer according to the invention.
