The management of radiation treatment error through incident learning.

Purpose: To assess efficacy of an incident learning system in the management of error in radiation treatment.

Materials And Methods: We report an incident learning system implementation customized for radiation therapy where any "unwanted or unexpected change from normal system behaviour that causes or has the potential to cause an adverse effect to persons or equipment" is reported, investigated and learned from. This system thus captures near-miss (potential) and actual events.

Optimization of stereotactic radiotherapy treatment delivery technique for base-of-skull meningiomas.

This study compares static conformal field (CF), intensity modulated radiotherapy (IMRT), and dynamic arcs (DA) for the stereotactic radiotherapy of base-of-skull meningiomas. Twenty-one cases of base-of-skull meningioma (median planning target volume [PTV] = 21.3 cm3) previously treated with stereotactic radiotherapy were replanned with each technique.

Does intensity modulation improve healthy tissue sparing in stereotactic radiosurgery of complex arteriovenous malformations?

This planning study evaluates the potential of intensity modulated treatment fields and inverse planning techniques in stereotactic radiosurgery to reduce healthy tissue dose. Twenty patients previously treated with stereotactic radiosurgery for arteriovenous malformation (AVM) were replanned with each of 4 techniques: circular non-coplanar arcs, dynamic arcs, static conformal fields, and intensity modulated radiosurgery (IMRS). Patients were selected having a maximum AVM dimension at least 20 mm, or volume greater than 10 cm(3).
