Size-Based Rendering for Lung Cancer Screening

We present two relevant clinical use cases for thoracic computed tomography data, where the recently introduced concept of size-based rendering can be beneficially applied to medical visualization in the context of screening for lung cancer and chronic obstructive pulmonary disease (COPD): (a) Gradual suppression of thorax and vessels for quick appraisal of the presence of pulmonary nodules. (b) Visualization of bullous versus diffuse emphysema. In the first use case, the opacity is chosen to decrease with local structure size, whereas in the second case, the opacity is chosen to increase with structure size. Both algorithms are robust in particular because they do not depend on any prior segmentation or classification. They are ideally suited for full parallelization and GPU implementation.
