However, recent advances in CTA technology, such as dual-source CT coronary artery angiography, have dramatically improved spatial and temporal resolution, leading to substantial improvement in image quality and significant reduction in radiation dose and use of contrast material (37).
As seen in our patient study, substantial improvement of image quality was achieved with real bones.
However, recent advances in hardware technology and pulse sequence design have led to substantial improvements in image quality, while reducing scan times to clinically reasonable durations.
Given the limited temporal resolution of CT, the tachycardia associated with a dobutamine stress study can result is substantial degradation of image quality.
The changing attenuation through different projections around the patient (e.g., at the level of the pelvis) can be used, to reduce unnecessary x-rays in the anterior posterior projection without any substantial effect on image quality [ 9, 41, 42].
Although the zero delay line is located anterior to the retina (on top of the image) and the size of the PED spans almost half of the available imaging range, the new PS-OCT system is capable to image the retina without a substantial reduction of image quality.
We discuss the module design concept and the results of the detailed Monte Carlo detector simulation, which inspire the architectural solutions selected for the layout and the front-end The expected resolution for 3D spatial coordinates of the interaction point in the crystal (1 mm) and the TOF (about 110 ps) would provide a substantial improvement of the image quality.
Due to the irregular heart rate, substantial image registration artefacts severely degraded image quality of CT raw data as well as subsequent post-processing images.
High image quality without substantial signal voids is favorable for AC [22].
The agreement between endocrinologists and gold standard on the image quality was substantial (κ = 0.61).
