SCIENZE INFORMATICHE E GESTIONE DELLE IMMAGINI

Learning Objectives

• ELECTRONIC AND INFORMATIC BIOENGINEERING

  Provide the student with the tools to deepen the techniques and methods of detection in Diagnostic Imaging in radiodiagnostics, nuclear medicine and radiotherapy fields.

• Information processing systems: image formation

  The course aims to make the student familiar with the formation process of analog and digital images, in order to provide the tools for evaluating the goodness of an imaging system, the requirements necessary for achieving a certain image quality degree and the main approaches for image enhancement and noise/artifact removal.

• PRODUCTION, PROCESSING, MANAGEMENT AND ARCHIVE OF IMAGES

  To know the general techniques and principles underlying the production, processing, and management of body images.

  To examine and evaluate the production of body images according to the different techniques of medical radiology.

  To acquire knowledge on the management and archive of bioimages
