Assessing HyperSight iterative CBCT for dose calculation in online adaptive radiotherapy for pelvis and breast patients compared to synthetic CT

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose/objectives Recent technological advancements have increased efficiency for clinical deliverability of online‐adaptive‐radiotherapy (oART). Previous cone‐beam‐computed‐tomography (CBCT) generations lacked the ability to provide reliable Hounsfield‐units (HU), thus requiring oART workflows to rely on synthetic‐CT (sCT) images derived ...

Freeze casting of hydroxyapatite scaffolds for bone tissue engineering [PDF]

Biomaterials, 27(32), 5480-5489 (2006), 2017
Although extensive efforts have been put into the development of porous scaffolds for bone regeneration, with encouraging results, all porous materials have a common limitation: the inherent lack of strength associated with porosity. Hence, the development of porous hydroxyapatite scaffolds has been hindered to non-load bearing applications.

Monitoring the setting of calcium sulphate bone-graft substitute using ultrasonic backscattering [PDF]

IEEE Transactions on Ultrasonics Ferroelectrics and Frequency Control, 66 (10), pp. 1658-1666, (2019), 2019
We report a method to monitor the setting process of bone-graft substitutes (calcium sulphate) using ultrasonic backscattering techniques. Analyzing the backscattered fields using a pulse-echo technique, we show that it is possible to dynamically describe the acoustic properties of the material which are linked to its setting state. Several experiments
