1 Radiosurgery by Leksell gamma knife Josef Novotny, Na Homolce Hospital, Prague
2 Radiosurgery - Definition Professor Lars Leksell The tools used by the surgeon must be adapted to the task and where the human brain is concerned they cannot be too refined.
3 Learning objectives * to learn basic principles of Leksell gamma knife (LGK) radiosurgery * to discuss imaging, treatment planning and optimisation procedures * to discuss quality assurance for LGK treatments * to present examples of diagnoses treated by LGK
4 Radiosurgery - Definition Radiation dose High Gamma Knife surgery Stereotactic Radiation Therapy The delivery of a single, high dose of irradiation to a small and critically located intracranial volume through the intact skull Image Guided Radiation Therapy Low Smaller Intensity Modulated Radiation Therapy Conformal Radiation Therapy Target volume Conventional Radiation Therapy Larger
5 Radiosurgery - Definition Radiation energy is focused into a small volume of soft tissue. This volume must be well defined regarding localization, size and shape. The energy is delivered in one single session Therefore the radiation energy must be delivered selectively to the volume and the radiosurgical procedure must be reproducible.
6 Radiosurgery - Definition Conformity describes how well the prescription dose is fitted to the target volume High conformity, low selectivity Selectivity also takes irradiation to normal tissue into account High conformity, high selectivity
7 Radiosurgery Components of selectivity A number of components are directly or indirectly important for high selectivity: Beam penumbra Radiation source size Intra-collimator leakage Inter-collimator leakage Beam size Dosimetrical uncertainties Mechanical stability Treatment planning system Number of radiation fields
8 Radiosurgery Fundamentals of radiosurgery For each radiosurgery technique, suitable targets are limited to certain sizes and shapes for which an adequate selectivity level can be achieved. This means that indications suitable for a certain technology are limited by the selectivity level needed for a clinically effective and safe treatment. This selectivity level will in practice be constantly re-defined according to the most sophisticated science and technology.

19 Leksell Gamma Knife - principles Leksell Gamma Knife C Leksell Gamma Knife PERFEXION - Increased treatable volume by more than 300% -Cerebral cases ~ 10% increase in available number of patients for existing indications due to extended reachability - Head & neck ~ 10 % additional patients from lesions in paranasal sinuses, orbits and some upper cervical lesions - Cervical lesions ~ 20% additional with upcoming fixation technique
20 Leksell Gamma Knife - principles Saving time: 1 hour / patient compared with Leksell Gamma Knife U/B 30 minutes / patient compared with Leksell Gamma Knife C/4C A real case study showed 4 hours for a 10 metastatic lesions patient Automation and workflow save 3-5 working weeks of physician time per year for a site with 200 patients per year Complete procedure implemented via one push button operation
