A Brief Survey of Spleen Segmentation in MRI and CT Images

The segmentation of the spleen is a challenging problem given the complicity and variability of abdominal anatomy. There are different imaging techniques, which are used in the medical diagnostic of this human organ. One of them is the magnetic resonance imaging (MRI), which gives good contrast between the different soft tissues of the body. This could be an important criterion for good image segmentation. However most of the researched segmentation techniques are applied to other popular type of medical images (Computer tomography - CT), but still could be used also for other image types. This paper gives a short classification of the modern methods for spleen segmentation that can be found in the specialized journals and that could be used with little improvements for most of the spleen medical images.
