A switching circuit includes a first switch and a second switch respectively connecting a first terminal and a second terminal of an electrical coil to a positive terminal of a voltage source, a third switch and a fourth switch respectively connecting the first terminal and the second terminal of the electrical coil to a negative terminal of the voltage source, and a controller to control the switching circuit in a current control mode to alternate a voltage polarity of the voltage source to thereby control a magnitude and direction of the electrical current of the electrical coil, and to control the switching circuit in a current hold mode to disconnect the electrical coil from the voltage source and to short-circuit the electrical coil to maintain the magnitude and direction of the electrical current at the transition time when the switching circuit switched to the current hold mode.

Method and circuit for muting electromagnetic interference during maneuvering of a device

Tracking based on the gradient fields of magnetic resonance imaging (MRI) scanners based on passive operation of the tracking system without any change of the scanner's hardware or mode of operation. To achieve better tracking performance, a technique to create a custom MRI pulse sequence is disclosed. Through this technique any standard pulse sequence of the scanner can be modified to include gradient activations specifically designated for tracking. These tracking gradient activations are added in a way that does not affect the image quality of the native sequence. The scan time may remain the same as with the native sequence or longer due to the additional gradient activations. The tracking system itself can use all the gradient activations (gradient activations for imaging and gradient activations for tracking) or eliminate some of the gradients and lock onto the specific gradient activations that are added to the custom pulse sequence.

Method and apparatus to estimate location and orientation of objects during magnetic resonance imaging

Endoscopic examining apparatus, particularly useful in MRI, includes a probe movable through the body cavity; a set of tracking coils carried by the probe; and a set of imaging coils carried by the probe. A control system controls the tracking coils to sense and indicate the location and orientation of the probe within the body cavity, and controls the imaging coils to image selected areas within the body cavity. Also described are a novel probe particularly useful in such apparatus, and a novel method of making such probes by a printed circuit technique.

A method of enhancing the image quality of cardiologic and general untrasound echo-doppler apparatus by finite memory, ECG-gated and/or breathing gated filtering of the acquired image. The acquired scans are time-gated by the cardiac contraction cycle, or by the breathing cycle to account for cardiac deformation due to contraction or relaxation, and to cardiac movements due to lung inflation or deflation, or to cardiac-induced pulse of perfusion in non-cardiac organs and tissues. The gated scans are recursively filtered with saved images, which are processed scans of previous cardiac and/or breathing cycles. The resulting images are displayed and also saved for the next cycle filtering process.
