Development of asynchronous educational applications in Nuclear Medicine, based on simulation.
This study involves the development of an open-access web-based platform, which
indicates the basic principles of medical imaging in Nuclear Medicine and
offers the user interactive tools to implement and configure the basic methods
of reconstruction and processing. The pedagogic content was developed using
creative Web design with graphical information and learning simulations that
closely resemble actual tomographic imaging systems. The interactive platform
is based on server-side .NET components created by MATLAB Deployment Tool and
incorporated in the developed .NET web application, using C# code. Client data,
like the user profile, is stored in a linked server database using SQL queries.
The educational platform was designed to include the basic concepts of the
DICOM protocol, the principles of acquiring projections forming the sinogram of
an imaged object, the principles of reconstructing tomographic images from
their projections using either the Filtered Back Projection (FBP) or Iterative
methods and image processing using a number of filters applied in the spatial
or frequency domains. Image reconstruction and processing algorithms were
implemented under a single user interface, thus giving the user the opportunity
to manipulate various factors and to understand the impact on image quality.
To estimate the educational value of the interactive simulation application we
conducted a prospective study of 115 students. The participants were asked to
answer an online questionnaire before and after the training with the
educational platform. After completing this task, all students had the
opportunity to evaluate the structure, the content and the interactivity of the
educational platform. The results from this pilot study suggest that the
developed application is a useful teaching tool as a supplement to, and not a
substitute for, the lecture-based medical education.
