Article Synopsis
- Dosimetric uncertainties in very small photon fields can affect the reliability of the virtual cone technique, prompting the evaluation of a fixed virtual cone (fVC) for small target radiosurgery.
- The fVC utilizes a 0.5 cm x 0.5 cm MLC field with high-definition beams and has been tested for its accuracy and reproducibility against treatment plans and various measurements.
- Results show that the fVC method offers comparable dosimetric accuracy to a physical cone and could be a viable option for routine treatment of conditions like trigeminal neuralgia.
Purpose: A novel form of lung functional imaging applied for functional avoidance radiation therapy has been developed that uses 4-dimensional computed tomography (4DCT) data and image processing techniques to calculate lung ventilation (4DCT-ventilation). Lung segmentation is a common step to define a region of interest for 4DCT-ventilation generation. The purpose of this study was to quantitatively evaluate the sensitivity of 4DCT-ventilation imaging using different lung segmentation methods.

However, achieving an accurate dose distribution in such cases is usually challenging due to the combination of numerous small fields ≤ (30 × 30) mm .
