Radiotherapy is, nowadays, an important tool on cancer therapy and at least 50% of cancer patients are subject to this treatment. Radiotherapy requires the use of the most advanced technology, allowing a higher accuracy of the treatment. This treatment requires a rigorous planning which involves the determination of a set of parameters (such as weights and limits) that will configurate the machine (linear accelerator) in order to define the radiation doses to prescribe. The planning time of the treatment depends on the characteristics of the clinical case to treat, ranging between some hours, in the simple cases, to days in the most complex cases. This fact, together with the human resources limitation of the institutions and the limited number of existing radiotherapy’s equipment, makes extremely important to find tools to optimize the creation of treatment plans, ensuring their quality. The development of mechanisms to automate the creation of radiotherapy treatment plans may improve the treatments in developed countries (where most people has access to the therapy), but it can also be extremely important in undeveloped and developing countries in which the majority
of the population is deprived of radiotherapeutic care.
The ORION project aims to create a comprehensive approach to the planning of radiotherapy treatments and enabling better management of human resources. It is intended to automate the treatment plan construction process, through the combination of imaging and 3D modulation editing techniques with optimization tools combined with artificial intelligence, reducing the time spent with this procedure, radically change the licensing paradigm of the software for treatment plans creation, currently in the pay-per-seat model, replacing it by the pay-per-use model, and bring closer the global demand and offer of dosimetrists, through the creation of a network joining professional and radiotherapy centres. This network will lead to a better use of the available human resources, increasing the efficiency of the Radiotherapy Centres around the world.
