1. Dose painting : Can radiotherapy be improved with image driven dose-responses derived from retrospective radiotherapy data?
Sammanfattning : The main aim of curative radiotherapy for cancer is to prescribe and deliver doses that eradicate the tumor and spare the normal healthy tissues. Radiotherapy is commonly performed by delivering a homogeneous radiation dose to the tumor. LÄS MER
2. Data Abstraction and Pattern Identification in Time-series Data
Sammanfattning : Data sources such as simulations, sensor networks across many application domains generate large volumes of time-series data which exhibit characteristics that evolve over time. Visual data analysis methods can help us in exploring and understanding the underlying patterns present in time-series data but, due to their ever-increasing size, the visual data analysis process can become complex.

3. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution
Sammanfattning : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. LÄS MER
