  2. 1. Quantification and optimisation of lung ventilation SPECT images

    Author : Pernilla Norberg; Michael Sandborg; Gudrun Alm Carlsson; Agneta Gustafsson; Katarina Sjögreen Gleisner; Linköpings universitet; []
    Keywords : ;

    Abstract : Currently, lung function tests are the gold standard for lung function measurements. Since the outcome of a lung function test is a summation of the status of the whole lung, significant changes in lung function may occur before a deviation from the norm can be identified. READ MORE

  4. 2. Evaluation of Regularized Image Reconstruction for Clinical Positron Emission Tomography

    Abstract : Positron emission tomography (PET) combined with computed tomography (CT) is a widely used noninvasive molecular imaging modality with a broad range of clinical applications in oncology, neurology, and cardiology. Producing imperative image quality and accurate quantification are important driving forces behind the technological advances within PET image reconstruction and system development. READ MORE

    Abstract : The PET-CT imaging modality is based on positron emission tomography combined with computed tomography. Before a PET-CT examination, a radioactive tracer (also called a radiopharmaceutical) is intravenously injected into the patient. PET technology images the distribution of this tracer element by detecting the decay. READ MORE
