The present invention will be understood from the following detailed description, taken in conjunction with the drawings in which:
As previously mentioned, mapping provides information to a physician regarding the state of a body part (e.g., the heart) in order for the physician to develop a treatment plan for the body part. The physician may also review other data, for example, electrocardiograms, previous ablation data, and local activation time (LAT) data superimposed on a map of the body part. The mapping may be performed using a catheter inserted into the body part with a view to performing treatment, such as ablation, while the catheter is still in the body part. In other cases, the catheter used for mapping may be removed before treatment is performed.
Analyzing the mapping data correctly, and sometimes quickly, is essential for correct and timely treatment. A user interface used to display the mapping data may offer various options for creating, editing and displaying the map, including different views, different formatting schemes, different coloring schemes, and adding annotations among other functions. The user interface may also provide options for displaying graphs and charts to convey the medical data.
It is important that the user interface is intuitive to use and allows the physician to create new maps and edit and format existing maps and other data while limiting blocking the view of the map(s).
Embodiments of the present invention solve the above problems by providing a medical mapping system including rendering a user interface including a display pane, which includes an anatomical map and other medical data, with a tab-based menu above the pane. The tab-based menu includes selectable ribbons including data readout elements and selectable controls (such as action buttons, sliders, toggle buttons, drop-down buttons, etc.) so that the menu may be navigated while limiting blocking of the display pane, which includes the anatomical map and other medical data. The tab-based menu also provides ease of use as the physician knows that most of the actions and readout elements are located in the menu ribbons.
In some embodiments, a medical mapping method includes receiving position data from a positioning sub-system which senses a position of a probe inserted into a body cavity of a living subject, and receiving at least one signal from at least one sensor of the probe. The sensor may provide position signals or other signals which may be used to compute force, proximity, tissue impedance, tissue temperature or electrical activity of the tissue by sensing electrical signals of the body cavity with at least one electrode of the probe. The method may also include computing position coordinates of a distal end of the probe responsively to the position data and rendering, to a display, a user interface screen including: a display pane including an anatomical map of the body cavity responsively to the computed position coordinates; and a tab-based menu above the pane. In some embodiments, the method may include rendering the anatomical map responsively to received signal(s) (e.g., position signal(s) and/or electrical signals captured from the tissue of the body cavity. In some embodiments, rendering the anatomical map may include rendering the anatomical map with electrophysiological data indicators, such as a LAT map using coloring, shading and/or vectors, responsively to the sensed electrical signals. In some embodiments, the method may include rendering a representation of the probe in the display pane responsively to the computed position coordinates and/or rendering ablation indicators (e.g., VisiTags) on the anatomical map.
The method may also include receiving a user selection selecting a tab of the tab-based menu and showing a horizontal ribbon of the selected tab above the pane in the user interface screen responsively to the received user selection. Generally, the display pane is not resized or even partially hidden responsively to showing the horizontal ribbon in the menu, thereby keeping the display pane clear for effective use by the physician. The method may include receiving a user selection of a selectable control of the displayed ribbon and performing an action associated with the selected control.
The ribbons of the menu may include any suitable data or controls. In some embodiments, the ribbons may include one or more data readout elements about any one or more of the following: ablation data; a tissue property; a selected point of the anatomical map; and tool connectivity. Additionally, or alternatively, the ribbons may include one or more controls to perform any one or more of the following: creation of the anatomical map; formatting the anatomical map; creation of an anatomical structure; editing the anatomical map; configuring the probe, taking a screen snapshot of the pane; recording the pane; selecting a preset layout of which panes to show; and creating custom layouts.
The user interface may include contextual activated tabs. For example, the method may include receiving a user selection of a selectable control of one of the ribbons and showing a contextual tab in the user interface screen responsively to the user selection of the selectable control. The contextual tab may include selectable controls, for example, to create a new map or a new anatomical structure from an existing map. One example of a contextual tab is a point-activated contextual tab. For example, the method may include receiving a user selection of a point on the anatomical map and showing a contextual tab (including data about the selected point) in the user interface screen responsively to the user selection of the point.
To allow ease-of-access to commonly used functions, the user interface may include a customizable quick access toolbar to which commonly used functions may be added. For example, the method may include receiving a user selection of a selectable control of one of the ribbons to add the selectable control to a quick access toolbar and showing a miniaturized representation of the selectable control in the quick access toolbar. The quick access toolbar may be shown above or below the active ribbon.
Turning now to the drawings, reference is initially made to
Areas determined to be abnormal, for example by evaluation of the electrical activation maps, can be ablated by application of thermal energy, e.g., by passage of radiofrequency electrical current through wires in the probe to one or more electrodes at the distal tip 18, which apply the radiofrequency energy to the myocardium. The energy is absorbed in the tissue, heating it to a temperature (typically about 50° C.) at which it permanently loses its electrical excitability. When successful, this procedure creates non-conducting lesions in the cardiac tissue, which disrupt the abnormal electrical pathway causing the arrhythmia. The principles of the invention can be applied to different heart chambers to diagnose and treat many different cardiac arrhythmias.
The probe 14 typically comprises a handle 20, having suitable controls on the handle to enable the operator 16 to steer, position and orient the distal tip 18 of the probe 14 as desired for the ablation. To aid the operator 16, a distal portion of the probe 14 contains position sensors 21 that provide signals to a processor 22, located in a console 24. The processor 22 may fulfill several processing functions as described below.
Ablation energy and electrical signals can be conveyed to and from the heart 12 through one or more ablation electrodes 32 located at or near the distal tip 18 via a cable 34 to the console 24. In such a manner, the ablation electrodes 32 are configured to capture electrical potentials over time at multiple sample locations over a surface of one or more chambers of the heart 12. Additionally, or alternatively, other electrodes may be configured to capture electrical potentials over time at multiple sample locations over a surface of one or more chambers of the heart 12. Pacing signals and other control signals may be conveyed from the console 24 through the cable 34 and the electrodes 32 to the heart 12. Sensing electrodes 33, also connected to the console 24, are disposed between the ablation electrodes 32 and have connections to the cable 34. The probe 14 may be implemented without the ablation electrodes 32 as an exploratory device having electrodes 33 configured to capture electrical potentials over time at multiple sample locations over a surface of one or more chambers of the heart 12.
Wire connections 35 link the console 24 with body surface electrodes 30 and other components of a positioning sub-system 27 for measuring location and orientation coordinates of the probe 14. The processor 22 or another processor (not shown) and the position sensors 21, ablation electrodes 32, and sensing electrodes 33 may be elements of the positioning subsystem. The electrodes 32 and the body surface electrodes 30 may be used to measure tissue impedance at the ablation site as taught in U.S. Pat. No. 7,536,218. A sensor for bioelectric information, e.g., a temperature sensor (not shown), typically a thermocouple or thermistor, may be mounted on or near each of the electrodes 32.
The console 24 typically contains one or more ablation power generators 25. The probe 14 may be adapted to conduct ablative energy to the heart using any known ablation technique, e.g., radiofrequency energy, ultrasound energy, and laser-produced light energy. Such methods are disclosed in U.S. Pat. Nos. 6,814,733, 6,997,924, and 7,156,816.
In one embodiment, the positioning subsystem 27 comprises a magnetic position tracking arrangement that determines the position and orientation of the probe 14 by generating magnetic fields using field generating coils 28 in a predefined working volume and sensing these fields at the probe 14 using the position sensors 21, which are implemented as magnetic coil sensors. The positioning subsystem 27 is described in U.S. Pat. Nos. 7,756,576, and 7,536,218.
In some embodiments, the processor 22 uses position-signals received from the ablation electrodes 32 and/or the sensing electrodes 33, and the position sensors 21 to estimate a position of the probe 14 inside an organ, such as inside a cardiac chamber. In some embodiments, the processor 22 correlates the position signals received from the electrodes 32, 33 with previously acquired magnetic location-calibrated position signals, to estimate the position of the probe 14 inside the organ. The position coordinates of the electrodes 32, 33 may be determined by the processor 22 based on, among other inputs, measured impedances, or on proportions of currents distribution, between the electrodes 32, 33 and the body surface electrodes 30.
The method of position sensing using current distribution measurements and/or external magnetic fields is implemented in various medical applications, for example, in the Carto® system, produced by Biosense Webster Inc. (Irvine, Calif.), and is described in detail in U.S. Pat. Nos. 5,391,199, 6,690,963, 6,484,118, 6,239,724, 6,618,612, 6,332,089, 7,756,576, 7,869,865, and 7,848,787, in PCT Patent Publication WO 96/05768, and in U.S. Patent Application Publication Nos. 2002/0065455 A1, 2003/0120150 A1 and 2004/0068178 A1.
The Carto®3 system applies an Active Current Location (ACL) impedance-based position-tracking method. In some embodiments, using the ACL method, the processor 22 is configured to create a mapping (e.g., current-position matrix (CPM)) between indications of electrical impedance and positions in a magnetic coordinate frame of the field generating coils 28. The processor 22 estimates the positions of the electrodes 32, 33 by performing a lookup in the CPM.
Other methods of determining the location of the distal end of the catheter may be used, for example, based on ultrasonic transducers and receivers, using imaging techniques such as ultrasound or MRI or CT scans which may include disposing radiopaque tags on the probe 14.
As noted above, the probe 14 is coupled to the console 24, which enables the operator 16 to observe and regulate the functions of the probe 14. The processor 22 may be embodied as a computer with appropriate signal processing circuits. The processor 22 is coupled to drive a monitor 29 including a display screen 37. The signal processing circuits typically receive, amplify, filter and digitize signals from the probe 14, including signals generated by sensors such as electrical, temperature and contact force sensors, and the ablation electrodes 32, sensing electrodes 33, position sensors 21 located distally in the probe 14. The digitized signals are received and used by the console 24 to compute the position and orientation of the probe 14, and to analyze the electrical signals from the electrodes 32, 33.
In order to generate electroanatomic maps, the processor 22 typically comprises an electroanatomic map generator, an image registration program, an image or data analysis program and a graphical user interface configured to present graphical information on the monitor 29.
In practice, some or all of these functions of the processor 22 may be combined in a single physical component or, alternatively, implemented using multiple physical components. These physical components may comprise hard-wired or programmable devices, or a combination of the two. In some embodiments, at least some of the functions of the processor 22 may be carried out by a programmable processor under the control of suitable software. This software may be downloaded to a device in electronic form, over a network, for example. Alternatively, or additionally, the software may be stored in tangible, non-transitory computer-readable storage media, such as optical, magnetic, or electronic memory.
The console 24 may also include an interface 39 to receive input commands from the operator 16 via any suitable user input device, for example, but not limited to, a pointing device (such as a mouse or stylus), a keyboard, and/or a touch sensitive screen implemented in the display screen 37.
Typically, the system 10 includes other elements, which are not shown in the figures for the sake of simplicity. For example, the system 10 may include an electrocardiogram (ECG) monitor, coupled to receive signals from the body surface electrodes 30, in order to provide an ECG synchronization signal to the console 24. The system 10 may include a reference position sensor, either on an externally applied reference patch attached to the exterior of the subject's body, or on an internally placed probe, which is inserted into the heart 12 maintained in a fixed position relative to the heart 12. Conventional pumps and lines for circulating liquids through the probe 14 for cooling the ablation site may be provided. The system 10 may receive image data from an external imaging modality, such as an MRI unit or the like and includes image processors that can be incorporated in or invoked by the processor 22 for generating and displaying images.
