1. Detection of pulmonary nodules in chest tomosynthesis: Comparison with chest radiography, evaluation of learning effects and investigation of radiation dose level dependency
Abstract : Chest tomosynthesis is a relatively recently introduced technique in healthcare, which produces section images of the chest at a lower radiation dose than computed tomography (CT) and with better depth resolution than conventional chest radiography. The primary aims of the studies described in this dissertation were to compare chest tomosynthesis with conventional radiography, to evaluate the effects of clinical experience and learning with feedback on the performance of observers analyzing tomosynthesis images, and to investigate the effect of radiation dose level in tomosynthesis, in the detection of pulmonary nodules.

2. Development of methods for evaluation and optimization of chest tomosynthesis
Abstract : Tomosynthesis is a low-dose technique that has attracted increasing interest from the medical imaging community during the past decade. Tomosynthesis refers to the technique of acquiring a number of projection radiographs using extremely low exposure over a limited angular range, and using these radiographs to reconstruct slices of the imaged object.

3. Chest Tomosynthesis for Detection and Surveillance of Pulmonary Pathology. Studies on Cystic Fibrosis and Solid Pulmonary Nodules
Abstract : Introduction: Digital tomosynthesis (DTS) is a relatively new imaging modality in thoracic imaging. The technique is based on the equipment of conventional radiography, upgraded with a moving tube that enables separation of structures that are superimposed on chest x-ray (CXR). READ MORE
