Detecting Drill Failure in the Small Short-sound Drill Dataset [PDF]
arXiv, 2021 Monitoring the conditions of machines is vital in the manufacturing industry. Early detection of faulty components in machines for stopping and repairing the failed components can minimize the downtime of the machine. This article presents an approach to detect the failure occurring in drill machines based on drill sounds from Valmet AB.

Measurement of CT radiation beam width with a pencil ionization chamber and radiopaque mask
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose This study compares fan beam CT scanner radiation beam widths measured with a pencil ionization chamber‐radiopaque mask technique with commonly used film and computed radiography (CR) measurements. Methods For a given fan beam CT scanner x‐ray beam, the ionization chamber‐mask technique determines the radiation beam width by exposing a

Evaluation of daily residual pancreatic tumor motion for deep‐inspiration breath‐hold radiotherapy
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Breath‐hold techniques are widely used in radiation therapy to minimize respiratory‐induced tumor or organ‐at‐risk motion. However, residual motion persists, necessitating a reliable daily evaluation method. Methods At our institution, fiducial markers serve as surrogates for target localization in pancreatic cancer treatment.
