Image quality and reconstruction intervals of dual-source CT coronary angiography: recommendations for ECG-pulsing windowing.
PURPOSE To evaluate reconstruction intervals and image quality in dual-source computed tomography (DSCT) coronary angiography for optimal placement of the ECG-pulsing window. MATERIALS AND METHODS DSCT coronary angiography was performed in 60 patients. Thirteen datasets were reconstructed in 5% increments from 20-80%. Two readers independently assessed image quality of each segment in each pe...
متن کاملProspective-triggered high-pitch spiral versus sequential dual-source CT coronary angiography: comparison of image quality and radiation dose
Background: Prospectively electrocardiography (ECG)-triggered high-pitch spiral coronary computed tomography angiography (CCTA) is a unique scan mode for dual-source CT (DSCT). Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates. Materials and Methods: Patients with low and stable ...
متن کاملDevelopment and Evaluation of Image Reconstruction Algorithms for a Novel Desktop SPECT System
Objective (s): Various iterative reconstruction algorithms in nuclear medicine have been introduced in the last three decades. For each new imaging system, it is wise to select appropriate image reconstruction algorithms and evaluate their performance. In this study, three approaches of image reconstruction were developed for a novel desktop open-gantry SPECT system, PERSPECT, to assess their p...
متن کاملRadiation Dose Reduction of Chest CT with Iterative Reconstruction in Image Space - Part I: Studies on Image Quality Using Dual Source CT
OBJECTIVE To determine whether the image quality (IQ) is improved with iterative reconstruction in image space (IRIS), and whether IRIS can be used for radiation reduction in chest CT. MATERIALS AND METHODS Standard dose chest CT (SDCT) in 50 patients and low dose chest CT (LDCT) in another 50 patients were performed, using a dual-source CT, with 120 kVp and same reference mAs (50 mAs for SDC...
متن کاملAccurate Image Reconstruction with Computed System Response Matrix for a High-Sensitivity Dual-Head PET Scanner
We have recently proposed a compact, dual-head PET scanner configuration for providing high-sensitivity imaging of small animals. Although the scanner is able to reach a sensitivity of about 30% at the center of imaging field-of-view, its compact configuration produces substantial depth-of-interaction (DOI) blurring and results in significantly degraded spatial resolution. It is known that DOI ...
