Comparison of log file-based and measurement-based QA for detecting MLC positional errors and evaluating dosimetric impacts of MLC defects. [PDF]

open access: yesJ Appl Clin Med Phys
Abstract Purpose This study aimed to compare the sensitivity of log file‐based quality assurance (LF‐QA) and measurement‐based quality assurance (MB‐QA) for detecting multileaf collimator (MLC) positional errors and to evaluate the dosimetric impacts of MLC mechanical drive train defects.

Nasopharyngeal Endoscopic Resection Extended to the Internal Carotid Artery (Type 4): Technical Notes, Indications, and Outcomes

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Endoscopic surgical approaches for nasopharyngeal malignancies, including recurrent nasopharyngeal carcinoma (rNPC) and nasopharyngeal salivary gland tumors (NSGT), have seen significant development over the last decades. Our groups have expanded the classification of nasopharyngeal endoscopic resections (NER) from type 1 to 3 to ...

Augmented Reality of Anatomical Structures of the Maxillomandibular Complex for Learning Dental Radiographic Techniques

open access: yesJournal of Dental Education, EarlyView.
ABSTRACT Introduction Augmented reality (AR) enables interactive learning in real‐world environments. In dental radiography education, AR offers a promising tool to enhance students' clinical skills by allowing them to simulate and practice procedures before engaging with actual patients. Repeated practice in an AR environment can reinforce theoretical

Oxide TFT‐Based Micro‐LED Pixel Circuit With Piecewise Linear Sweep Slope Signal for Improved Low Gray‐Level Expression

open access: yesJournal of the Society for Information Display, EarlyView.
An oxide TFT‐based micro‐LED PWM pixel circuit employing a piecewise linear sweep signal is proposed. By separating low‐ and high‐gray emission phases, the circuit reduces the falling time by 70% and achieves accurate low‐gray‐level expression down to 41 G, enabling compact and stable operation for next‐generation micro‐LED displays.

System Integration and Field Testing of Low‐Cost Autonomous Platooning Platforms: Collision Avoidance Scenario

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper presents the development and validation of a scalable platooning system based on the predecessor‐following (PF) topology, designed for low‐cost follower platforms. It integrates key technologies such as localization, path planning, profile generation, and low‐level control to create a practical solution.
