Effect of high-pitch dual-source CT to compensate motion artifacts: a phantom study.
RATIONALE AND OBJECTIVES To evaluate the potential of high-pitch, dual-source computed tomography (DSCT) for compensation of motion artifacts. MATERIALS AND METHODS Motion artifacts were created using a moving chest/cardiac phantom with integrated stents at different velocities (from 0 to 4-6 cm/s) parallel (z direction), transverse (x direction), and diagonal (x and z direction combined) to ...
متن کاملTemporal Resolution and Motion Artifacts in Dual-Source Cardiac CT and Single-Source CT with Iterative Reconstruction
The temporal resolution (TR) of an image has become an important property in computed tomography (CT) when examining organs whose motion can not be stopped for the duration of the CT scan, such as in cardiac CT. In this context, “higher TR” conventionally means that the raw data from which a given image was reconstructed was measured within a shorter time interval than the raw data of a similar...
متن کاملA novel dual energy CT-based attenuation correction method in PET/CT systems: A phantom study
In present PET/CT scanners, PET attenuation correction is performed by relying on the information given by CT scan. In the CT-based attenuation correction methods, dual-energy technique (DECT) is the most accurate approach, which has been limited due to the increasing patient dose. In this feasibility study, we have introduced a new method that can implement dual-en...
متن کاملTemporal Resolution Improvement in Single Source and Dual Source CT
Purpose: Recently a new method called TRIPICCS (Temporal Resolution Improved Prior Image Constrained Compressed Sensing) was proposed to improve the temporal resolution of a single source (SS) cardiac CT scan [1] (figures 1+2). This method aims at doubling the temporal resolution and at maintaining homogeneous temporal resolution independently of the location and the motion direction of a vesse...
