Dynamic Screening for Therapeutic Diagnosis and Radiation Therapy for Oncological Patients
Anatomical and topographical tumor extension may be determined with a variety of imaging systems. In addition to their functions as diagnostic devices for the examination of tumors, Ultrasound, Computer Tomography, and Magnetic Resonance are used either in combination with a therapy simulator or as therapy simulators. The use of Ultrasound for therapy simulation is limited. Although compound ultrasound scanners provide body contours (contour representation is not on a 1:1 scale), measurements of tumor extension tend to be inaccurate or require optimal conditions such as tumor localization in the abdomen. Ultrasound is contraindicated for treatment planning of intrathoracic processes. Sonography should only be used to monitor treatment.
