Radiation Therapy Beam Modulation Techniques,rapy was to limit the normal tissue dose by conforming the treatment field to the beam’s-eye view (BEV) projection of the target volume under continuous rotation of the gantry [1]. A multileaf collimator (MLC) is generally used to efficiently collimate the multiple fields. Initial clinical trials ar

Both strategies are best illustrated by the therapeutic ratio, which is the ratio of the probability of tumor control to the probability of normal tissue injury (Figure 7-1). The therapeutic ratio can be improved by localizing a radiati

Recent Advances in External Electromagnetic Hyperthermia, yet to be convincingly demonstrated in multicenter randomized phase III clinical trials. Two phase III clinical studies combining irradiation and hyperthermia performed in the United States [1,2] have shown benefit only in small tumors (≤3 cm in diameter). However, recently completed multicenter ph
