Abstract(s)
A Realidade Virtual (RV) tem vindo a estar progressivamente mais presente no nosso quotidiano,
em particular em diversos contextos de treino. Na área da Medicina, a RV é usada, por exemplo, em
simuladores de treino de intervenções cirúrgicas e de realização de diversos tipos de exames
médicos. Estes simuladores permitem aos profissionais de saúde treinar e aperfeiçoar técnicas rigorosas
em ambientes simulados, mas próximos da realidade, sem o risco de complicações para doentes reais.
O aparecimento recente de equipamentos portáteis e de baixo custo para a realização de ecografias
torácicas, permite que estes exames possam ser efetuados em condições adversas e em que a deslocação
do doente a um hospital não é viável. Porém, esta possibilidade, em termos de acesso mais abrangente
a um diagnóstico médico, faz surgir a necessidade de treinar pessoas não-especializadas para que sejam
capazes de realizar este tipo de exames.
Neste projeto foi concebida e desenvolvida a aplicação Android, chamada EchoLung, que
apresentada dois modos: Training Mode (do inglês, Modo de Treino) e Teaching Mode (do inglês, Modo
de Ensino). O foco deste projeto será o Training Mode, onde é possível simular a realização de uma
ecografia torácica a um modelo 3D de um Torso de um doente virtual, utilizando um tablet como ecrã
de visualização, e a movimentação do smartphone para controlar a sonda virtual em tempo-real, obtendo
assim imagens médicas correspondentes às zonas analisadas, iguais às geradas por um ecógrafo.
O modo de treino da aplicação foi testado pelo médico internista da equipa que identificou as suas
mais-valias e os aspetos a melhorar no futuro e por um conjunto de 10 pessoas que nunca realizaram
estes exames. Estes utilizadores responderam ao questionário System Usability Scale para avaliar a
usabilidade da EchoLung, tendo-se obtido uma pontuação de 97.25 (melhor usabilidade possível).
Virtual Reality (VR) has become progressively more present in our daily lives in different training contexts. In the area of Medicine, VR is used, for example, in training simulators for surgical interventions and for carrying out different types of medical examinations. These simulators allow healthcare professionals to train and perfect rigorous techniques in simulated environments, but close to reality, without the risk of complications for real patients. The recent appearance of portable and low-cost equipment for performing thoracic ultrasounds allows these exams to be performed in adverse conditions and in which the patient's travel to a hospital is not feasible. However, this possibility, in terms of more comprehensive access to a medical diagnosis, raises the need to train non-specialized people to be able to carry out this type of examination. In this project, an Android application was conceived and developed, called EchoLung, which presents two modes: Training Mode and Teaching Mode. The focus of this project will be the Training Mode, where it is possible to simulate the performance of a thoracic ultrasound on a 3D model of a Torso of a virtual patient, using a tablet as a visualization screen, and the movement of the smartphone to control the virtual probe in real-time, thus obtaining medical images corresponding to the analyzed areas, similar to those generated by an ultrasound. The application's training mode was tested by the team's internist, who identified its benefits and aspects to be improved in the future, and by a group of 10 people who had never performed these exams. These users answered the System Usability Scale questionnaire to assess the usability of the EchoLung, obtaining a score of 97.25 (best possible usability).
