TLDR
In this paper, a volume visualization technique for generating a 3D visualization image of an internal organ using volume visualization techniques is presented. But this technique is not suitable for the visualization of complex 3D objects.Abstract:
Methods for generating a three-dimensional visualization image of an object, such as an internal organ, using volume visualization techniques are provided. The techniques include a multi-scan imaging method; a multi-resolution imaging method; and a method for generating a skeleton of a complex three dimension object. The applications include virtual cystoscopy, virtual laryngoscopy, virtual angiography, among others.read more

Generating three-dimensional models from images
TL;DR: In this article, multi-view semantic segmentation is provided to recognize and segment images at the pixel level into semantically meaningful areas, and which can provide labels with a specific object class.
Patent
Image processing method and image processing program
TL;DR: In this paper, an image processing method of visualizing information of a living body near an imaginary path is described. But the method is not suitable for the analysis of human motion.
Patent
System and method to evaluate electrode position and spacing
TL;DR: In this article, a selected current can be generated between two electrodes, either external or internal in the patient, and a voltage can be measured by one or more electrodes of the IMD.
Patent
Resonator for medical device
