Abstract(s)
O presente trabalho visa colmatar uma necessidade de mercado, uma mesa de Radioterapia de morfologia adaptável. Pretende-se estudar e desenvolver uma mesa e seus sistemas que permitam uma conformação perfeita ao corpo de qualquer paciente, garantindo que o mesmo esteja mais confortável durante o tratamento de Radioterapia.
O desenvolvimento do trabalho iniciou-se por um estudo de mercado, onde se consultou bibliografia sobre Radioterapia, as soluções atuais de imobilização para este tipo de tratamento, a sensibilidade à dor e patentes sobre mesas, camas e macas de conformação ao corpo humano. Constatou-se que efetivamente houve um grande avanço tecnológico no equipamento que induz o tratamento (Aceleradores Lineares), mas não nos sistemas de imobilização. Assim, procedeu-se à análise de várias hipóteses conceptuais de projeto para uma mesa que se pudesse conformar a um corpo humano de forma expedita sem que infligisse dor nem fosse contra a natureza do tratamento. Exploraram-se possibilidades pneumáticas, hidráulicas, elétricas, de suporte robotizado externo, entre outras até se chegar a um conceito de projeto válido e exequível.
Aquando da definição das linhas diretrizes iniciou-se o processo de modelação em software de desenho assistido por computador (CAD) dos vários componentes. Durante este processo, como é típico da conceção de um produto, houve vários avanços e recuos, que, no entanto, ficaram documentados bem como as suas vantagens/desvantagens. O estudo considerou também a análise detalhada de alguns elementos críticos que compõem a mesa de Radioterapia de morfologia adaptável com suporte em software de engenharia assistida por computador (CAE).
Com base na solução de projeto desenvolvida neste trabalho e num conjunto de ilações retiradas dos estudos realizados, são deixadas algumas sugestões para desenvolvimentos futuros.
The present work aims at filling a market need, a Radiotherapy table with adaptive morphology. It is intended to study and develop a table and its systems that allow a perfect conformation to the body of any patient, ensuring that patient it is more comfortable during the Radiotherapy treatment. The development of the work began with a market study, where we consulted a bibliography on Linear Accelerators, Radiation Therapy, the current immobilization solutions for this type of treatment, pain sensitivity and patents on tables, beds and body shaping stretchers. It was found that there was indeed a great technological advance in the machine that induces the treatment, but not in the immobilization systems. Several hypotheses were analyzed to arrive at a table that could conform to a human body expeditiously without inflicting pain or against the nature of the treatment. Pneumatic, hydraulic, electrical, external robotic support, among others possibilities were explored, until the concept of a valid project was reached. When the guidelines were defined, the modeling process of the various components was started in computer-aided design (CAD) software. During this process, as is typical of the producto design, there have been several advances and setbacks, which, however, have been documented as well as their advantages / disadvantages. The study also considered the detailed analysis of some critical elements that make the Radiotherapy table of adaptive morphology with support in Computer Aided Engineering (CAE) software. Based on the project solution developed in this work and on a set of lessons learned from the studies carried out, some suggestions for future developments are left.
