My Ph.D. project is mostly focused on breast MRI and the aim is to propose an automated workflow for lesion detection, segmentation and sub-type classification of carcinoma tumors through state-of-the-art machine learning techniques. 

Research Focus: Lesions sub-type classification, tumor segmentation, and behavior investigation.

Semi-Automatic Algorithm for Breast MRI Lesion Segmentation Using Marker-Controlled Watershed Transformation

Magnetic resonance imaging (MRI) is an effective imaging modality for identifying and localizing breast lesions in women.Accurate and precise lesion segmentation using a computer-aided-diagnosis (CAD) system, is a crucial step in evaluating tumor volume and in the quantification of tumor characteristics. However, this is a challenging task, since breast lesions have sophisticated shape, topological structure, and high variance in their intensity distribution across patients. We proposed a novel marker-controlled watershed transformation-based approach, which uses the brightest pixels in a region of interest (determined by experts) as markers to overcome this challenge, and accurately segment lesions in breast MRI. The proposed approach was evaluated on 106 lesions, which includes 64 malignant and 42 benign cases.  

The results illustrate that the proposed method shows promise for future work related to the segmentation and classification of benign and malignant breast lesions.


Breast DCE-MRI Lesion Segmentation and Classification

Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI) recently proved to be quite helpful in screening high-risk women and in staging newly diagnosed breast cancer patients. Accurate segmentation of tumor lesion and selection of suspicious regions of interest (ROIs) is a critical pre-processing step in DCE-MRI data evaluation. The goal of this project is to develop and evaluate methods for automatic and semi-automatic detection of suspicious ROIs for breast DCE-MRI, segmentation of tumor lesions, morphological feature extraction and classification of tumors in terms of benign and malignant. I will try to use deep learning algorithms as state-of-the-art approaches for every possible stages. This project is partly connected to Big-Thera project and the patients data are provided by Radiology department of Killinikum University of Erlangen.
