Description
Technical field
The present invention relates to medicine equipment control technology field, especially a kind of method of Dynamic controlling radiotherapy planning system, specifically a kind of method of the Dynamic controlling radiotherapy planning system based on external program.
Background technology
Radiotherapy treatment planning system (Treatment Planning System, TPS) is that radiotherapy department physics teacher or dosage teacher are used for designing the technology platform of radiotherapy planning and important medicine equipment.Physics teacher or dosage teacher are by the 3-dimensional image of patient and doctor's dose prescription input TPS, then rule of thumb drawing target outline, vitals and accessory organ, the best launched field of placement, various optimization aim is set, the optimization finally carrying out planning calculates, calculate the distribution of most suitable beam and intensity, thus obtain radiotherapy planning.If result of calculation can not meet prescription requirements, operating personnel will adjust various parameter further and continue to optimize, until obtain satisfactory result.
What the optimisation technique of at present general in the world TPS adopted is based on multiobject unconfinement type optimisation technique.This technology uses modern optimization algorithm, as CG (Conjugate Gradient) algorithm or genetic algorithm, search optimum Intensity Modulation Radiated Therapy (IMRT) plan by minimizing a cost function combining multiple clinical target of vying each other and constraint condition according to different weight.This can be expressed by following formula based on multiobject unconfinement type optimization problem:
Wherein,
for the parameter sets of above-mentioned optimization problem, which represent the weight of various dosage distribution limitation and each optimization aim;
with
be respectively planned target number and vitals number,
for the intensity distributions of beam,
for the ray beam intensity of optimum distributes.Owing to only having a cost function, this algorithm has computing velocity advantage comparatively fast compared with traditional restricted type optimisation technique.If be combined with the clinical experience of tumour radiotherapy doctor, this algorithm can produce feasible treatment plan.At present, based on the Intensity Modulation Radiated Therapy (IMRT) planning system software TPS of this technology, as the Pinnacle system of Philips company and the Eclipse system etc. of Varian company, tumour hospital is at home and abroad widely applied.Wherein, although the function that Pinnacle system has partially restrained to optimize, this function is seldom used because operational efficiency is too low.
Although achieve very ten-strike based on the radiotherapy planning system (TPS) of multiobject unconfinement type optimisation technique in clinical practice, along with progressively going deep into of application, it encounters very large challenge in extensibility and configurability.Operationally see, current TPS is automanual.Radiotherapy department physics teacher or dosage teacher need manual by the 3-dimensional image of patient and doctor's dose prescription input TPS on this system, then rule of thumb drawing target outline, vitals and accessory organ, the best launched field of placement, various optimization aim is set, the optimization finally carrying out planning calculates.If result of calculation can not meet prescription requirements, operating personnel will adjust various parameter further and continue to optimize, until obtain satisfactory result.The physics teacher of each hospital has different plan design experiences, and has the demand of robotization manual steps in various degree.In order to meet the demand of the physics teacher robotization design experiences step separately of Different hospital, the TPS systems such as Pinnacle and Eclipse provide the inside script system that automatically can operate from internal system command system.But the grammer of these inner script system is too simple, is authoritatively substantially, flexibly and accurately control device such as Row control, object-oriented and the programming mode etc. that seldom have modern high-level programming language to have.This makes TPS have too many difficulties to cope with in expansion and the dirigibility configured, accuracy and automatism etc.
