PET medical image analysis improved in order to optimize radiotherapy treatments
Date:6/11/2013

Elena Prieto-Azkarate, a graduate in Telecommunications Engineering at the NUP/UPNA-Public University of Navarre and member of the Nuclear Medicine Service of the University College Hospital of Navarre, has implemented 12 algorithms to process medical images produced by means of PET (Positron Emission Tomography). As she points out in her PhD thesis, read at the NUP/UPNA, the results obtained are highly promising and this technique could be very useful indeed.She has also developed a graphics interface that will enable the doctor or oncologist to use this technique in clinical practice comfortably, rapidly and intuitively.

The research comes within the field of biomedical engineering and was carried out through collaboration between the Nuclear Medicine Service of the University College Hospital of Navarre and the NUP/UPNA-Public University of Navarre. The thesis is entitled "Segmentacin mediante umbralizacin automtica en tomografa por emisin de positrones" (Segmentation through automatic thresholding in positron emission tomography).

The PET technique makes it possible to gather molecular images that provide information about the biological and metabolic behaviour of tumours.Recent years have seen the emergence of great interest in the potential of images of this type in the planning of courses of radiotherapy treatment.In this planning the most critical process is the exact delimitation of the volume of the tumour requiring treatment.

So Elena Prieto has improved the segmentation technique of PET images."The segmentation of an image," she explains, "is an image processing technique that allows objects to be delimited; tumours, in this case.This thesis sought to conduct research into and develop new segmentation techniques to turn PET (Positron Emission Tomography) into a reliable alternative for treatment planning in Radiotherapeutic Oncology."
