Evaluation of a Time-of-Flight-based Respiratory Motion Management System
نویسندگان
چکیده
In this paper a novel anatomic-like phantom, to simulate human respiratory motion is presented. The phantom is capable to simulate thorax and abdomen motion for surface based respiratory gating systems. This phantom is used to evaluate a system based on time-of-flight (TOF) technology, to detect respiratory motion. It could be shown that the correlation between the reference motion, performed by the phantom and the measured data of the TOF system is 0.65 for a breathing amplitude of 1.5mm and above 0.80 for amplitudes bigger than 5 mm. Furthermore, the system is capable to detect a breathing frequency of at least 25 respiratory cycles per minute.

A Novel Method for Ultrasonic Evaluation of Horizontal Defects Using Time-of-Flight Diffraction
Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...

A new non-invasive method for diagnosis of sleep apnea, this diagnosis method is based on respiratory motion visualization with a Time of Flight (ToF) camera. The 3D movie taken with this camera visualizes the patient movements while he/she is sleeping, and the respiratory motion is extracted, analyzed and displayed in real time. This method can also be useful in sport medicine or for YOGA prac...

An implicit unsteady upwind solver including a mesh motion approach was applied to simulate a helicopter including body, main rotor and tail rotor in hover flight. The discretization was based on a second order finite volume approach with fluxes given by the Roeand#39;s scheme. Discretization of Geometric Conservation Laws (GCL) was devised in such a way that the three-dimensional flows on arbi...

The gimbal stabilization mechanism system is used to provide the stability to an object mounted on the gimbal by isolating it from the base angular motion and vibration. In this paper the model of one axis gimbal system with dynamics flying object is introduced. The gimbal torque relationships are obtained using Newton’s second law equation on the assumption that gimbal is rigid body. The syste...
متن کاملStress Analysis of Flight Vehicles under Flight Conditions
A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...
