Abstract:
A spot scanning (SS) ion therapy system configured for dynamic trimming of an ion particle pencil beam to reduce the amount of the radiation dosage outside of a target boundary.
Abstract:
A system (10) for visualizing and modifying the thickness of a compensator (26) for radiation therapy in the context of a desired target and dose coverage thereof includes planar slice image generation module (40), a visualization unit (42) and an adjustment module (44). The planar slice image generation module (40) generates a series of planar slice images (24) from a patient image data set (14) disposed with one axis parallel to a radiation beam and one axis perpendicular to the radiation beam (22). The visualization unit (42) graphically depicts a compensator thickness profile (26), a target of interest (28), and/or a dose representation on at least one of the series of planar slice images (24) all in the same plane lying in a beam's longitudinal direction. The adjustment module (44) receives user input of an adjustment of at least one compensator thickness value via a manipulation of the graphical depiction thereof.
Abstract:
The present invention relates to a method for the in vitro determination of the radiosensitivity of a subject. More particularly, the invention relates to a method comprising a step of inducing an exogenous stress on a biological sample from a subject, followed by the comparison of the presence or level of at least one compound chosen in a group of defined compounds, in said biological sample and in a reference sample. The present invention also relates to the use of said at least one compound as predictive biomarker of the radio–sensitivity of a subject. The invention also relates to a kit for the detection of the presence or level of at least one of said compounds, usable in a method according to the invention.
Abstract:
Systems and apparatuses for providing particle beams for radiation therapy with a compact design and suitable to a single treatment room. The radiation system comprises a stationary cyclotron coupled to a rotating gantry assembly through a beam line assembly. The system is equipped with a single set of dipole magnets that are installed on the rotating gantry assembly and undertakes the dual functions of beam energy selection and beam deflection. The energy degrader may be exposed to the air pressure. The beam line assembly comprises a rotating segment and a stationary segment that are separated from each other through an intermediate segment that is exposed to an ambient pressure.
Abstract:
Verfahren zur Bestrahlungsplanung eines Zielvolumens (34) mit einem gescannten Partikelstrahl (20), umfassend die Schritte: Festlegen eines in einem Körper (77) angeordneten Zielvolumens (34), Unterteilen des Zielvolumens (34) in eine Vielzahl einzeln anfahrbarer Zielpunkte (30), Festlegen einer Anzahl von zeitlich konsekutiven Teilbestrahlungsplänen, Aufteilen der Zielpunkte (30) des Zielvolumens (34) in Teilmengen (A, B, C, D) auf die Teilbestrahlungspläne, wobei die Teilmengen (A, B, C, D) über das gesamte Zielvolumen (34) verteilt sind und wobei zueinander benachbarte Zielpunkte (30) des Zielvolumens (34) jeweils unterschiedlichen Teilbestrahlungsplänen zugeordnet werden.
Abstract:
Treatment volume projection systems and methods for use in treating patients, including an image scanner to capture an image of a patient's treatment volume, a processor to process the image to generate a treatment volume image corresponding to at least a portion of the treatment volume, and an image projector to project the treatment volume image onto a projection surface. The treatment volume image can include an x-y scanning area of the treatment volume to assist delivery of treatment to the patient.
