Groeblacher Labs, at the TU Delft tries to achieve entanglement using optomechanical resonators like nanobeams. This is done by using the side peaks generated by the optomechanical resonators. These peaks are separated by 5 GHz in relation to the resonance peak of the optomechanical resonator. Because …

This paper reviews the literature for lowering of dose to paediatric patients through use of exposure factors and additional filtration. Dose reference levels set by The International Commission on Radiological Protection (ICRP) will be considered. Guidance was put in place in 1996 requires updating …

Purpose: To determine whether using different combinations of kVp and mAs with additional filtration can reduce the effective dose to a paediatric phantom whilst maintaining diagnostic image quality. Methods: 27 images of a paediatric AP pelvis phantom were acquired with different kVp, mAs and additional …
