Methods, apparatus, and systems for medical procedures are disclosed herein and include a catheter having a first electrode and a second electrode, the first electrode configured to transmit first electromagnetic signals and the second electrode configured to transmit second electromagnetic signals. A first patch, a second patch, and a third patch each configured to receive the first and second electromagnetic signals are included and arranged in a triangular formation on a first surface of a patient's body. A first catheter position relative to the first patch, the second patch, and the third patch, is determined at a first time and a second time. The first catheter position and the second catheter position relative to the first catheter position may be displayed such that the first catheter position is visually connected to the second catheter position.

Detection of catheter location, orientation, and movement direction

In one embodiment, a system includes a catheter, at least one position sensor to provide position signal(s) indicative of a position of a distal end of the catheter over time, a first smoothing filter to provide first filtered position signal(s) responsively to the position signal(s) and a first filtering level, a second smoothing filter to provide second filtered position signal(s) responsively to the position signal(s) and a second filtering level, wherein the second filtering level provides more smoothing than the first filtering level, and processing circuitry to find first and second position coordinates of the distal end responsively to the first and second filtered position signal(s), respectively, generate, and render to a display, an anatomical map of a body part responsively to the second position coordinates, and render a representation of the distal end to the display while showing movement of the distal end responsively to the first position coordinates.

Reducing perceived latency of catheters

A system includes multiple electrically-conductive channels and a processor. The processor is configured to receive, over the electrically-conductive channels, (i) respective first electric currents from a probe, which is within a body of a patient, via a plurality of first electrodes, which are attached to skin of the patient at a region of the body, and (ii) a second electric current from the probe via a second electrode, which is attached to the skin and is connected to one of the channels. The processor is further configured to ascertain respective first electric-current values of the first electric currents and a second electric-current value of the second electric current, and to calculate a position of the probe between the region and the second electrode, based on the first electric-current values and the second electric-current value. Other embodiments are also described.

Extending the tracking volume in a probe tracking system

A medical display processing device and a method of reusing data includes acquiring, over time via electrodes, electrical signals each acquired via one of the electrodes and indicating electrical activity at a location of a portion of patient anatomy in a 3D space. Electrical signal data, corresponding to the electrical signals, is filtered according to first filter parameter settings and first mapping information is generated for displaying a map of the portion of patient anatomy and the filtered electrical signal data. An indication of a region of the portion of patient anatomy on the map is received and second mapping information is generated for displaying, at the region on the map, a portion of the electrical signal data previously filtered from display.

Data reuse for filling in missing data points

Methods, apparatus, and systems are provided for facilitating the navigation of a catheter between first and second locations within a subject based on display of serial images corresponding to positions of the catheter at successive incremental times. Image production includes sensing catheter positions to produce location data for each time increment. For each position P, the corresponding location data is processed to respectively produce an image Ireflecting the position of the catheter at a time T. Each image Iis successively displayed at a time equal to T+d, where d is an image processing visualization delay. Upon a condition that the catheter is displaced to a selected interim location between the first and second locations, the processing of the location data is switched from being performed by a first process associated with a first visualization delay to a second process associated with a second different visualization delay.
