  1. 11. 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. 12. Accuracy of Quantification for Renography with 99mTc-MAG3: A Study on Virtual and Clinical Data

    University essay from Lunds universitet/Medicinsk strålningsfysik, Lund

    Author : Irma Ceric; [2016]
    Keywords : Medicine and Health Sciences;

    Abstract : Aim: Renography with 99mTc-MAG3 is one of the most common nuclear medicine examinations. It’s extensive use justifies a thorough investigation of the methods used to accurately determine the split renal function, for instance with regard to background subtraction and correction for renal depth differ- ences.

  4. 13. 3D Scintillation Positioning Method in a Breast-specific Gamma Camera

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

    Author : Beien Wang; [2015]
    Keywords : ;

    Abstract : In modern clinical practice, gamma camera is one of the most important imaging modalities for tumour diagnosis. The standard technique uses scintillator-based gamma cameras equipped with parallel-hole collimator to detect the planar position of γ photon interaction (scintillation). READ MORE

    Keywords : gamma camera; breast imaging; monte carlo simulation; depth of interaction;

    Abstract : In modern clinical practice, gamma camera is one of the most important imaging modalities for tumour diagnosis. The standard technique uses scintillator-based gamma cameras equipped with parallel-hole collimator to detect the planar position of γ photon interaction (scintillation). READ MORE

  6. 15. Feasibility of Implementing the PILATUS CdTe 300k Detector as a Real Time Gamma Camera in Intraoperative Medical Imaging

    University essay from Lunds universitet/MAX IV-laboratoriet; Lunds universitet/Fysiska institutionen

    Author : Mariam Andersson; [2015]
    Keywords : PILATUS; CdTe; detector; medical imaging; lymphoscintigraphy; sentinel lymph node biopsy; quantum efficiency; resolution; sensitivity; semiconductor detector; gamma camera; Physics and Astronomy;

    Abstract : The full-width-at-half-maximum of the point spread functions for a pixellated cadmium telluride detector exposed to gammas from a 140.5 keV Tc-99m source are modelled in GATE, at a detector-collimator distance of 5 cm, and collimator-source distances of 5 cm and 10 cm, with lead pinholes of diameter 1.0 mm, 1.5 mm, 2.
