Advanced Catheter Navigation System with Hybrid Rendering and Real-Time Adaptive Feedback

An enhanced catheter navigation system that combines hybrid rendering techniques with real-time adaptive feedback to improve lesion visibility and navigation accuracy, addressing limitations of existing systems.

The original patent's system for displaying an alignment CT has limitations in terms of lesion visibility and navigation accuracy. The new inventive concept addresses these limitations by introducing a hybrid rendering technique that combines Maximum Intensity Projection (MIP) and Volume Rendering (VR) to improve visibility of lesions located beyond objects, and real-time adaptive rendering that adjusts the level of transparency and highlighting based on the catheter's position and orientation.

The advanced catheter navigation system comprises a catheter navigable within a patient's airways and a computing device operably coupled to the catheter. The computing device is configured to generate a hybrid view of the patient's airways, combining MIP and VR techniques to improve visibility of lesions. The system also employs a real-time adaptive rendering technique that adjusts the level of transparency and highlighting based on the catheter's position and orientation, providing the user with accurate and intuitive navigation guidance. Additionally, the system may apply a region-growing algorithm to identify regions of interest and render them using a novel transfer function that adjusts the voxel density based on the proximity of the catheter to the lesion.

The new claims introduce a novel hybrid rendering technique that combines MIP and VR, and a real-time adaptive rendering technique that adjusts the level of transparency and highlighting based on the catheter's position and orientation. These features are not present in the original patent and provide a significant improvement in lesion visibility and navigation accuracy.

Alternative embodiments of the inventive concept may include using different rendering techniques, such as surface rendering or ray casting, or incorporating additional sensors or tracking systems to improve navigation accuracy. Variations of the system may also be implemented for different medical applications, such as cardiac or neurovascular procedures.

The advanced catheter navigation system has significant commercial potential in the medical device industry, particularly in the areas of pulmonary and cardiovascular procedures. The system's improved lesion visibility and navigation accuracy can reduce procedure times, improve patient outcomes, and increase the adoption of minimally invasive procedures.
