1. Image inpainting methods for elimination of non-anatomical objects in medical images
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This project studies the removal of non-anatomical objects from medical images. During tumor ablation procedures, the ablation probes appear in the image, hindering the performance of segmentation, registration, and dose computation algorithms. These algorithms can also be affected by artifacts and noise generated by body implants. READ MORE

2. Needle Navigation for Image Guided Brachytherapy of Gynecologic Cancer
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : In the past twenty years, the combination of the advances in medical imaging technologies and therapeutic methods had a great impact in developing minimally invasive interventional procedures. Although the use of medical imaging for the surgery and therapy guidance dates back to the early days of x-ray discovery, there is an increasing evidence in using the new imaging modalities such as computed tomography (CT), magnetic reso- nance imaging (MRI) and ultrasound in the operating rooms.

3. Simulation of radio-frequency ablation of liver tumors : Development of a power regulation model and comparison with microwave ablation
University essay from Mekanisk värmeteori och strömningsläraAbstract : Local therapy with radiofrequency ablation (RFA) is an important method for treating liver tumors mostly in early stage, which has been increasingly used in recent years. RFA utilizes an RF current that is applied to the target tissue through an electrode connected with a power generator and percutaneously inserted into the tumor; the electrode power causes the tissue temperature rise required for destroying cancer cells.
