1. 1. Evaluation of differences in attenuation pattern for myocardial perfusion scintigraphy between CZT and conventional gamma cameras

   University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

   Author : Elin Martinsson; [2016]
   Keywords : Medicine and Health Sciences;

   Abstract : The new CZT camera has a different technology compared to conventional scintillation gamma cameras. The CZT camera have pinholes instead of parallel hole collimators, a static gantry instead of a rotating one and detection material made of a semiconductor in- stead of a scintillation crystal.

3. 2. Presentation and evaluation of gated-SPECT myocardial perfusion images : Radial Slices - data reduction without  loss  of  information

   University essay from KTH/Skolan för teknik och hälsa (STH)

   Author : Darvish Darvish; F.Nadideh Öçba; [2013]
   Keywords : SPECT; Myocardial perfusion Imaging; Short Axis; Vertical Horizontal Long Axis; radial slices;

   Abstract :   Single photon emission tomography (SPECT) data from myocardial perfusion imaging (MPI) are normally displayed as a set of three slices orthogonal to the left ventricular (LV) long axis for both ECG-gated (GSPECT) and non-gated SPECT studies. The total number of slices presented for assessment depends on the size of the heart, but is typically in excess of 30. READ MORE

4. 3. Automatic registration of myocardial perfusion images

   University essay from Lunds universitet/Matematik LTH

   Author : Daniel Svensson; [2012]
   Keywords : Mathematics and Statistics;

   Abstract : Myocardial perfusion is an indicator of heart health that can be used to locate damaged areas of the heart. It can be measured by an imaging modality such as magnetic resonance imaging (MRI). When measuring myocardial perfusion in a living human we must align images over time to correct for motion caused by breathing. READ MORE

5. 4. Segmentation and Alignment of 3-D Transaxial Myocardial Perfusion Images and Automatic Dopamin Transporter Quantification

   University essay from Medicinsk informatik; Tekniska högskolan

   Author : Leo Bergnéhr; [2008]
   Keywords : Segmentation; Morphon; SPECT; Myocardial; DAT;

   Abstract : Nukleärmedicinska bilder som exempelvis SPECT (Single Photon Emission Tomogra-phy) är en bildgenererande teknik som ofta används i många applikationer vid mätning av fysiologiska egenskaper i den mänskliga kroppen. En vanlig sorts undersökning som använder sig av SPECT är myokardiell perfusion (blodflöde i hjärtvävnaden), som ofta används för att undersöka t. READ MORE

6. 5. Analysis of the Benefit of Quantification in Myocardial Perfusion Imaging A human observer ROC evaluation using Monte Carlo Simulated Data

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Yassin Rouwaida; [2005]
   Keywords : Nukleärmedicin; Medicine and Health Sciences;

   Abstract : "The purpose of this study was to evaluate the benefit of commercial quantification software in perfusion SPECT imaging by simulating a group of patients and their corresponding SPECT acquisitions using a computer phantom and a Monte Carlo program. Based on decisions from experienced physicians and their visual interpretation of the simulated patient images, without and with addition of the information from the quantitative perfusion software, the benefit of such a quantification program was evaluated from a ROC analysis.
