Thus reduced scanning times would presumably increase the quality of reconstructions due to a decrease of thermal drifts and vibrations.
Major improvements in technology have improved resolution and reduced scanning times in CT examinations, which have helped to minimize the need for sedation in children.
These improvements may enhance knee diagnosis with higher image quality and reduced scan time.
Technical advances with improved spatial and temporal resolution and subsequently reduced scan time and radiation exposure have allowed cardiac CT to simultaneously assess both coronary anatomy and myocardial perfusion.
New hardware designs such as dual modality systems (SPECT-CT, PET-CT, and PET-MR) and dedicated cardiac cameras with optimal detector geometric arrays, linear count statistics, and count rate response allow for lower-dose imaging, reduced scan time, and improved image quality [ 6, 7].
Parallel imaging was utilized with an acceleration factor of 2.5 to reduce scanning time to approximately 4 min.
The use of CT for attenuation correction negates the need for traditional transmission attenuation correction, reducing scanning time.
The following methods are known to reduce scanning time: 1) The cantilever resonant frequency [ω0] is increased by reducing cantilever size (and mass) and increasing its stiffness.
Choosing a sequence of events that maximizes efficiency of estimating the HDR is essential for conducting event-related brain imaging experiments, since increasing efficiency is essentially equivalent to reducing scanning time or increasing the strength of the principal magnetic field.
