Resolution-Complete Inverse Treatment Planning in Radiosurgery
Treatment planning in radiosurgery and radiation therapy involves a large number of medical and technical constraints. The main technical constraints stem from the gantry kinematics and the type of collimator available. The gantry kinematics (i.e. number and spatial arrangement of movable joint axes) determines the type of motion which can be performed by the therapeutic beam. The collimator de...
متن کاملInverse treatment planning for Gamma Knife radiosurgery.
An inverse treatment planning system for Gamma Knife radiosurgery has been developed using nonlinear programming techniques. The system optimizes the shot sizes, locations, and weights for Gamma Knife treatments. In the patient's prescription, the user can specify both the maximum number of shots of radiation and a minimum isodose line that must surround the entire treatment volume. After satis...
متن کاملMonte Carlo-based inverse treatment planning.
A Monte Carlo based inverse treatment planning system (MCI) has been developed which combines arguably the most accurate dose calculation method (Monte Carlo particle transport) with a 'guaranteed' optimization method (simulated annealing). A distribution of photons is specified in the tumour volume; they are transported using an adjoint calculation method to outside the patient surface to buil...
متن کاملClinical interventions and outcomes of One-to-One midwifery practice.
BACKGROUND Changing Childbirth became policy for the maternity services in England in 1994 and remains policy. One-to-One midwifery was implemented to achieve the targets set. It was the first time such a service had been implemented in the Health Service. An evaluation was undertaken to compare its performance with conventional maternity care. METHODS This was a prospective comparative study...
