Three-dimensional displacement analysis of the thumb CM joint based on the bone axis using X-ray CT images

Nihon Kikai Gakkai ronbunshu, 2022
Thumb carpometacarpal (CM) joint osteoarthritis is a common disease in elderly. To clarify the thumb CM joint motion is critical to reveal the factor of disease and improve treatment methods.

Evaluation of the influence of the clips geometry on the mechanical stresses generated on the thumb during assembly work

بهداشت و ایمنی کار, 2017
Introduction: Nowadays, Snap-fits have many applications in the automotive industry, especially in assembly lines. They are used instead of the mechanical joints such as bolts, the cabling joints, and the car interior lining joints.

Assessing proton plans with three different beam delivery systems versus photon plans for head and neck tumors

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose To compare plan quality among photon volumetric modulated arc therapy (VMAT) and intensity‐modulated proton therapy (IMPT) with robustness using three different proton beam delivery systems with various spot size (σ) ranges: cyclotron‐generated proton beams (CPBs) (σ: 2.7–7.0 mm), linear accelerator proton beams (LPBs) (σ: 2.9–5.5 mm),

Radiation-induced thumbs carcinoma due to practicing dental X-ray

Contemporary Clinical Dentistry, 2015
Dealing with diagnostic X-ray radiation may result in serious health problems, unless protection guidelines are followed. This became prevalent immediately a decade following the invention of X-ray radiation, where it had not been known that the ...

IROC phantoms accurately detect MLC delivery errors

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose We evaluated the impact of random and whole‐bank multileaf collimator (MLC) delivery errors on dosimetric delivery accuracy in the Imaging and Radiation Oncology Core (IROC) phantom audits, as well as differences in delivery accuracy between the IROC phantom prescription and typical clinical fraction sizes.

An Unusual Case of Volar Dislocation of Thumb Metacarpophalangeal Joint

Journal of Orthopaedics, Trauma and Rehabilitation, 2015
Thumb metacarpophalangeal joint dislocation is an uncommon injury. Most of the dislocations are dorsal, and volar dislocation is rare. Only a total of 18 cases of volar dislocation of thumb metacarpophalangeal joint are published in English and other ...

Simulated Tom Thumb, the Rule Of Thumb for Autonomous Robots [PDF]

arXiv, 2012
For a mobile robot to be truly autonomous, it must solve the simultaneous localization and mapping (SLAM) problem. We develop a new metaheuristic algorithm called Simulated Tom Thumb (STT), based on the detailed adventure of the clever Tom Thumb and advances in researches relating to path planning based on potential functions.

The effect of multi‐leaf collimator leaf width on VMAT treatment plan quality

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background The advent of volumetric modulated arc therapy (VMAT) in radiotherapy has made it one of the most commonly used techniques in clinical practice. VMAT is the delivery of intensity modulated radiation therapy (IMRT) while the gantry is in motion, and existing literature has shown it has decreased treatment delivery times and the ...

From 2D to 3D gamma passing rate tolerance and action limits for patient‐specific quality assurance in volumetric‐modulated arc therapy

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Volumetric modulated arc therapy (VMAT) requires an accurate patient‐specific quality assurance (PSQA) program. In clinical practice, this is usually performed using the γ‐index and the two‐dimensional gamma passing rate (2D %GP). A three‐dimensional (3D) index incorporating the patient anatomy could be more useful for the 3D dose ...
