AbstractID: 9807 Title: Clinical implementation of respiration motion correlated
imaging, treatment planning and delivery
Respiratory motion is a significant factor in determining a suitable planning target
volume (PTV) that surrounds the demonstrable gross tumor volume (GTV) in the
radiotherapy of mobile lesions. The advent of respiratory phase correlation (4D) and
multi-slice CT technology has enabled patient-specific determination of both
demonstrable tumor volume and its motion from a single acquisition. Management of
such additional information during treatment planning and delivery however presents
several challenges. Furthermore, guidelines for establishing clinical treatment planning
and delivery protocols based on respiratory correlated imaging data differ from one
institution to the other. The purpose of this presentation is to educate the community on
the different respiratory correlated radiotherapy approaches currently available and
compare the benefits and pitfalls in each case. Special focus will be on treatment
planning, dose calculation and treatment delivery related issues.
After the course, the attendees should be able to:
1) Understand the different respiratory correlated treatment planning and
delivery approaches
2) Compare the benefits and pitfalls of each of the above approaches
3) Develop and establish respiratory correlated imaging, treatment planning and
delivery appropriate to the available equipment
