This paper reviewed three state-of-the-art image fusion methods that were developed based on the estimation theory and evaluated these methods in the fusion of PET/CT images for radiotherapy applications. These fusion methods were developed in a framework of maximum likelihood estimate and firstly introduced the expectation-maximization algorithm to image fusion at either pixel-level or feature-level.

Objective: We present a full description of our virtual mammography simulator, which was already introduced in a previous short version. Herewith we give many details omitted there. Materials: We work with a professional mammographer and a transparent breast phantom. The phantom contains artificial nodules, and their displacement under compression can be easily tracked through a transparency sheet with a printed Read More

This study aimed to evaluate the effect of intravenous (IV) contrast media on semi quantification value during fluorine-18 fluorodeoxyglucose (18F-FDG) PET/CT in cancer imaging. We reviewed whole body 18F-FDG PET/CT scans of 51 oncology cases performed with and without IV contrast administration. Non contrast-enhanced CT (NECT) images were acquired following IV injection of FDG then followed by contrast-enhance Read More

Spectral imaging technology is an emerging modality that combines the advantages of both imaging and spectroscopy (high spatial and spectral resolution) in one device. The technology has potential in numerous medical imaging and diagnostic applications. In this review, we describe the techniques used to acquire spectral images and the methods used for analyzing spectral images. We then provide detailed review about Read More

Myocardial infarction (MI) and heart failure (HF) are leading causes of mortality and morbidity in the Western World. Therapeutic approaches using interventional cardiology and bioengineering techniques have thus far focused on either salvaging viable tissue post-infarction or preserving cardiac function in the failing myocardium. Regenerative medicine on the other hand, attempts to renew damaged tissue and enhance Read More
