In radiation therapy, malignant tumors are treated with radiation while sparing healthy organs. It is an essential treatment method used for the majority of cancer patients.
During the course of the treatment, which is applied daily over several weeks, changes in the size of the tumor, the patient's body weight, and the body's movement while breathing, can affect the tumor's position. This can lead to a partial tumor miss during treatment. To decrease the risk of missing parts of the tumor, large safety margins surrounding the mutated cells are often included in the region targeted for irradiation. As an unintended consequence, healthy tissue is also damaged.
The expandable radiotherapy software system (SPARTA) addresses this problem. With an accurate measuring of variations, a precise calculation of the delivered dose, a detailed analysis of the tumor, and an adequately adapted treatment plan, variations of the patient's body are taken into account. In so doing, the researchers aim to increase the safety and effectiveness of radiation therapy for patients.
