Proposta de simulador computacional de exames de joelho em ressonância magnética para fins didáticos

Abstract

Taking into account the increasing use of computational technologies and the increasing use of virtual reality programs to supplement student education, the work has the objective of elaborating software that simulates the steps and parameters for the practice of performing Magnetic Resonance (MRI) knee exams. For the accomplishment of this objective we searched and used sequences of images acquired in Knee MRI examination in different weights and anatomical planes. The construction of the simulation made use of Adobe software packages (Adobe Flash CS3 and Adobe Photoshop CS3) for design and programming. Variable buttons of the parameters used in the acquisition of the RM images (repetition time, echo time, Field of view and number of cuts) were programmed. Button programming enabled the user to select different combinations of parameters resulting in different sequences of images with Different weights. In the construction of the application, only parameters and images acquired in the SE pulse sequence were used, resulting in T1, T2 and proton density-weighted images. With the elaboration of this application it is expected to provide new didactic practices in Magnetic Resonance classes Assisting the teaching and learning process of radiology students, improving their professional practice.
