Patient-specific bronchoscope simulation with pq-space-based 2D/3D registration.
OBJECTIVE The use of patient-specific models for surgical simulation requires photorealistic rendering of 3D structure and surface properties. For bronchoscope simulation, this requires augmenting virtual bronchoscope views generated from 3D tomographic data with patient-specific bronchoscope videos. To facilitate matching of video images to the geometry extracted from 3D tomographic data, this...
متن کاملNon-rigid 2D-3D Registration with Catheter Tip EM Tracking for Patient Specific Bronchoscope Simulation
This paper investigates the use of Active Shape Models (ASM) to capture the variability of the intra-thoracic airway tree. The method significantly reduces the dimensionality of the non-rigid 2D/3D registration problem and leads to a rapid and robust registration framework. In this study, EM tracking data has been also incorporated through a probabilistic framework for providing a statistically...
متن کاملAtrioventricular Blood Flow Simulation Based on Patient-Specific Data
We propose a new framework for simulating blood flow inside the heart, usable with geometric models of the heart from patientspecific data. The method is geared toward realistic simulation of blood flow, taking into account not only heart wall motion but also valve motion. The simulator uses finite differences to discretize a domain that includes a functional model of the left ventricle and the...
متن کاملSelective image similarity measure for bronchoscope tracking based on image registration
We propose a selective method of measurement for computing image similarities based on characteristic structure extraction and demonstrate its application to flexible endoscope navigation, in particular to a bronchoscope navigation system. Camera motion tracking is a fundamental function required for image-guided treatment or therapy systems. In recent years, an ultra-tiny electromagnetic senso...
متن کاملBronchoscope Tracking Based on Image Registration Using Multiple Initial Starting Points Estimated by Motion Prediction
This paper presents a method for tracking a bronchoscope based on motion prediction and image registration from multiple initial starting points as a function of a bronchoscope navigation system. We try to improve performance of bronchoscope tracking based on image registration using multiple initial guesses estimated using motion prediction. This method basically tracks a bronchoscopic camera ...
