Abstract:
Medical image quality assessment is critical and indispensable for comparing and optimizing medical imaging systems such as acquisition systems, image post-processing systems and visualization systems. Since the ultimate goal of medical images is to aid clinicians in rendering a diagnosis, it is widely accepted that in order to optimize diagnostic decisions image quality should be as good as possible. The task-based approach is fundamental and popular in the context of medical imaging. The underlying paradigm is to quantify the quality of a particular image by its effectiveness with respect to its intended task. In the seminar, different model observers proposed in the framework of task-based approach will be presented, as well as the methods for their validation and performance evaluation.
