    摘要: A method for visualizing the quality of an ablation process with a processing and display unit is provided. A 3D dataset of an anatomical object and a 3D image model of an ablation instrument are provided, wherein the 3D image model models at least the surface of the ablation instrument. A position and an alignment of the 3D image model of the ablation instrument within the anatomical object is specified, wherein the 3D image model of the ablation instrument is incorporated into the 3D dataset of the anatomical object. At least a part of the incorporated 3D image model of the ablation instrument and of the 3D dataset of the anatomical object is presented and at least one characteristic quality value is determined as a function of the location of the 3D image model of the ablation instrument in relation to the anatomical object.

    摘要: A method and system for detecting and tracking multiple catheters in a fluoroscopic image sequence in an integrated central processing unit and graphics processing unit framework is disclosed. A catheter electrode model is initialized in a first frame of the fluoroscopic image sequence. The catheter landmark candidates are detected, by a graphics processing unit, in the first frame of the fluoroscopic image sequence. The catheter electrode model is tracked, by a central processing unit, and is detected by the graphics processing unit, in subsequent frames of the fluoroscopic image sequence by detecting catheter landmark candidates in the subsequent frames of the fluoroscopic image sequence using at least one trained catheter landmark detector, and outputting the catheter model tracking and landmark detection results of for each frame of the fluoroscopic image sequence.
