摘要： The invention relates to electrophysiology catheter systems and their use, such as in an MRI environment, and in particular to analysis of electric signals from such. An electrophysiology (EP) catheter with a plurality of electrically isolated electrode segments arranged in longitudinally spaced bands around the catheter is used to detect electric signals. A workstation receives the electrical signals which are then processed by a processing unit. Electric signals from electrode segments can be used to determine roll angle information of the catheter in relation to patient anatomy by determining signals from electrode segments in contact with tissue. Also, electric signals can be used to extract a reference signal that can be used to correct for gradient induced artefacts.

摘要： The invention relates to a modified Laser Optical Feedback Tomography sensor (10) which comprises an evaluator (16) for the determination of an object velocity (vz) relative to the sensor (10). The primary optical frequency (f o ) of light emitted by a laser (11) is shifted by a first frequency shift F in a frequency shifter (13) and focused into an investigation region (3). A moving object (2) in said region produces an additional Doppler frequency shift ?F in the light sent back from the investigation region (3) which is re-injected into the laser (11). Resulting intensity oscillations of the laser (11), which critically depend on the shifted frequency of the re-injected light, are detected by a detector (15). Finally, the evaluator (16) coupled to the detector (15) determines from the observed oscillations the Doppler frequency shift ?F and therefrom the moving velocity (V z ) of the object (2).

摘要： The invention relates to a method for the selective amplification of signal photons of a signal pulse (4) in a desired time window. For this purpose, the signal photons (4) are passed through an activated amplification medium (1), where amplification takes place by induced emissions. The amplification is terminated at a desired point in time by the irradiation of a quench pulse (7). Optionally, the start of amplification can be determined by an irradiated pump pulse (8). Emissions that are not correlated with the signal pulse (4) can be suppressed by means of a spectral filter (2). Furthermore, an intensity filter such as a saturable absorber (3) can suppress unamplified fractions of the emission (5) leaving the amplification medium (1). Applications of the method include medical optical imaging and tomography by transillumination with time-gated detection of ballistic photons.

The magnetic tracking system comprises pairs of first (21a, 22a, 23a) and second (21b, 22b, 23b) field generators that are disposed on opposite sides of a measuring volume (V). The first field generators may particularly be attached to the radiation source (13) and the second field generators (21b, 22b, 23b) to the detector (11) of an X-ray device. Moreover, the first and second field generators may be constituted by coils with opposite magnetic polarity. Due to the attachment of the field generators to the X-ray device, motions of the X-ray device do not disturb the magnetic field (B) in a frame of reference fixed to the imaging system.
