Device lines up for small-field dosimetry
High-resolution dosimetry is important for all radiation therapy techniques, but most critical for the newer conformal treatment modalities that employ small radiation fields. At the extreme, stereotactic radiotherapy and radiosurgery typically use field sizes of less than 4 cm, and at times as small as 5 mm. Such regimes necessitate tighter target margins and pose stringent dosimetry demands.
