Experimental evaluation of beam tracking for 3D motion
نویسندگان
چکیده
The beam delivery system of the carbon ion therapy at GSI has been modified to perform beam tracking [1,2]. Beam tracking is achieved by monitoring the target motion and by adapting the pencil beam in lateral (magnetically) and in longitudinal direction (motorized wedge absorbers). The updated integrated system was experimentally tested for left-right target motion with depth changes that were induced by a ramp shape absorber positioned in front of the moving target [2]. We report on experiments that evaluated the tracking accuracy for 3D target motion in water.

A quantitative investigation on lung tumor site on its motion tracking in radiotherapy with external surrogates
Introduction: In external beam radiotherapy each effort is done to deliver 3D dose distribution onto the tumor volume uniformly, while minimizing the dose to healthy organs at the same time. Radiation treatment of tumors located at thorax region such as lung and liver has a challenging issue during target localization since these tumors move mainly due to respiration. There are...
متن کاملDosimetric precision of an ion beam tracking system
BACKGROUND Scanned ion beam therapy of intra-fractionally moving tumors requires motion mitigation. GSI proposed beam tracking and performed several experimental studies to analyse the dosimetric precision of the system for scanned carbon beams. METHODS A beam tracking system has been developed and integrated in the scanned carbon ion beam therapy unit at GSI. The system adapts pencil beam po...

In this paper the problems of state estimation, tracking control and shape control in a micro-cantilever beam with nonlinear electrostatic actuation are investigated. The system’s partial differential equation of motion is converted into a set of ordinary differential equations by projection method. Observabillity of the system is proven and a state estimation system is designed using extended ...

The purpose of this work is to extract three-dimensional (3D) motion trajectories of internal implanted and external skin-attached markers from kV cone-beam projections and reduce image artifact from patient motion in cone-beam computed tomography (CBCT) from on-board imager. Cone beam radiographic projections were acquired for a mobile phantom and liver patients with internal implanted and ext...
متن کامل4D optimization of scanned ion beam tracking therapy for moving tumors.
Motion mitigation strategies are needed to fully realize the theoretical advantages of scanned ion beam therapy for patients with moving tumors. The purpose of this study was to determine whether a new four-dimensional (4D) optimization approach for scanned-ion-beam tracking could reduce dose to avoidance volumes near a moving target while maintaining target dose coverage, compared to an existi...
