A Visibility-based Algorithm for Multi-robot Boundary Coverage

open access: yesInternational Journal of Advanced Robotic Systems, 2008
Cell decomposition is often used in autonomous area coverage. We propose a visibility-based decomposition algorithm for single robot boundary coverage and a corresponding multi-robot algorithm in unknown environment.

Measurement of CT radiation beam width with a pencil ionization chamber and radiopaque mask

open access: yesJournal 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
