ABSTRACT
The imaging is a process to investigate a reality that escapes directly to the human eye producing a visual representation. Several applications have been developed up to now, that span from biological investigations to the validation of scientific hypotheses (Hudson et al. 2007). A field of investigation that makes an increasing use of the imaging process is the biomedical one. Biomedical imaging makes possible to observe an area of a body no visible from the outside with the aim to use advanced diagnostic and therapeutic techniques in order to improve the effectiveness of biomedical process (Marion et al. 2011). According to different investigative objectives some examples of important technology based on biomedical imaging are: endoscopy, ultrasound, eco-doppler, computed tomography, magnetic resonance imaging, angiography, mammography, positron emission tomography (PET), single photon emission tomography (SPECT).
