    摘要: Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Abschätzen der Größe eines Hohlraumes in einem Gegenstand, ein Verfahren zum Herstellen der Vorrichtung und ein Verfahren zur Vorbereitung einer Brachytherapie. Die Größe des Hohlraumes wird durch Einführen der Vorrichtung in den Hohlraum und die dabei vermittelte haptische Wahrnehmung durch eine Person abgeschätzt. Die Vorrichtung umfasst eine Halterung zum Greifen der Vorrichtung durch die Person und einen oder mehrere mit der Halterung mechanisch verbundene Messkörper. Die Messkörper haben unterschiedliche Formen und Größen. Die Messkörper können durch eine Kennzeichnung eindeutig gekennzeichnet sein. Die Vorrichtung ist überwiegend durch ein Spritzgussverfahren herstellbar und kann aus einem medizinisch geeigneten Material bestehen.

    摘要: The invention relates to a method of MR imaging of a body (10) of a patient positioned in an examination volume of an MR device (1). It is an object of the invention to provide a method that enables geometrically correct MR-only radiation therapy planning at minimum scan times. The method of the invention comprises the following steps: acquiring first MR imaging data representative of at least one region of the body (10); analyzing said first MR imaging data to delineate at least one anatomical structure within said body region; acquiring second MR imaging data of said body region using a multi-point Dixon sequence; deriving a B0 map from said second MR imaging data; analyzing said B0 map to determine at least one low fidelity region of said B0 map; performing B0 mapping to refine the B0 map using a multi-acquisition gradient echo sequence restricted to at least one region where said delineated anatomical structure and said low fidelity region overlap completely or partially; and correcting geometrical distortions in said first and/or second MR imaging data using the refined B0 map. Moreover, the invention relates to a MR device (1) for carrying out the method, and to a computer program to be executed on a MR device (1).

    摘要: A method may include obtaining a first image related to one or more target objects generated by a first scan. The method may also include obtaining a first radiation therapy plan for treating the one or more target objects. The method may also include obtaining a second image related to the one or more target objects generated by a second scan. The second scan may be performed later than the first scan. The method may also include determining, based on the first radiation therapy plan, the first image, and the second image, a target radiation therapy plan to treat the one or more target objects. The target radiation therapy plan may be the first radiation therapy plan or a second radiation therapy plan associated with the second image, wherein at least a portion of the determining the target radiation therapy plan may be performed in parallel.
