Design and validation of a novel dosimetry phantom for motion management audits
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background We present a novel phantom design for conducting end‐to‐end dosimetry audits for respiratory motion management of two anatomical treatment sites. The design enables radiochromic film measurements of the dose administered to the target throughout the respiratory cycle (motion‐included) and the dose delivered to the time‐averaged ...

Hydrodynamic Noise Reduction [PDF]
The Journal of the Acoustical Society of America, 1961 The reduction of hydrodynamic noise resulting from singing and cavitation was a serious problem in a recent wire-guided high-speed underwater missile development. The noise level of this body not only was sufficiently high to prevent a model of the latest developed sonar from tracking other bodies, but permitted a possible enemy more than sufficient ...

Log file‐based quality assurance method for respiratory gating system
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

Shearlet-Based Adaptive Noise Reduction in CT Images
Iranian Journal of Electrical and Electronic Engineering, 2021 The noise in reconstructed slices of X-ray Computed Tomography (CT) is of unknown distribution, non-stationary, oriented and difficult to distinguish from main structural information. This requires the development of special post-processing methods based

Machine stability and dosimetry for ultra‐high dose rate FLASH radiotherapy human clinical protocol
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The FLASH effect, induced by ultra‐high dose rate (UHDR) irradiations, offers the potential to spare normal tissue while effectively treating tumors. It is important to achieve precise and accurate dose delivery and to establish reliable detector systems, particularly for clinical trials needed to help the clinical transfer of FLASH‐

QuietPaw: Learning Quadrupedal Locomotion with Versatile Noise Preference Alignment [PDF]
arXivWhen operating at their full capacity, quadrupedal robots can produce loud footstep noise, which can be disruptive in human-centered environments like homes, offices, and hospitals. As a result, balancing locomotion performance with noise constraints is crucial for the successful real-world deployment of quadrupedal robots.

Reduction of Traffic Noise [PDF]
Nature, 1934 THE report in NATURE of October 20, p. 633, of a discussion on this subject at the recent meeting of the British Association at Aberdeen encourages the hope that the attention of competent minds directed to the reduction of sound in motor traffic may have practical results.
