Radiation Dose Reduction in Computed Tomography- Guided Lung Interventions using an Iterative Reconstruction Technique CT-gesteuerte Interventionen an der Lunge: Dosisreduktion mithilfe iterativer Rekonstruktionsalgorithmen
Ziel: Vergleich der Dosis und Bildqualität bei CTgesteuerten Interventionen unter Verwendung eines Standarddosisprotokolls (SDCT) mit gefilterter Rückprojektion (FBP) und eines Niedrigdosisprotokolls (LDCT) mit FBP und iterativer Rekonstruktion (IR). Material und Methoden: Retrospektiv wurde die Bildqualität und Strahlendosis (Dosislängenprodukt und CTDI) bei 130 Patienten, die sich einer CT-ge...
متن کاملRadiation dose reduction in pediatric great vessel stent computed tomography using iterative reconstruction: A phantom study
BACKGROUND To study dose reduction using iterative reconstruction (IR) for pediatric great vessel stent computed tomography (CT). METHODS Five different great vessel stents were separately placed in a gel-containing plastic holder within an anthropomorphic chest phantom. The stent lumen was filled with diluted contrast gel. CT acquisitions were performed at routine dose, 52% and 81% reduced d...
متن کامل[Fluoroscopy dose reduction of computed tomography guided chest interventional radiology using real-time iterative reconstruction].
The purpose of this study was to evaluate the radiation dose reduction to patients and radiologists in computed tomography (CT) guided examinations for the thoracic region using CT fluoroscopy. Image quality evaluation of the real-time filtered back-projection (RT-FBP) images and the real-time adaptive iterative dose reduction (RT-AIDR) images was carried out on noise and artifacts that were co...
متن کاملDose Reduction Methods in Chest Computed Tomography
Introduction: Computed tomography is one of the most powerful tools for investigating thorax disease, because it shows progression of lung disease much clearer than chest radiography. Technical advances in CT scanners have led to some abilities for CT scanners such as coverage of larger volume, lower noise and ability for acquiring image in one respiratory phase. However, this will be accompani...
متن کاملX-Ray Dose Reduction in Abdominal Computed Tomography Using Advanced Iterative Reconstruction Algorithms
OBJECTIVE This work aims to explore the effects of adaptive statistical iterative reconstruction (ASiR) and model-based iterative reconstruction (MBIR) algorithms in reducing computed tomography (CT) radiation dosages in abdominal imaging. METHODS CT scans on a standard male phantom were performed at different tube currents. Images at the different tube currents were reconstructed with the fi...
