Abstract:

An optical motion sensing system () for use in imaging an anatomical structure employs an optical motion sensor () including a body contour conforming matrix (“BCCM”) () and an optical fiber (). Upon BCCM () being adjoined to the anatomical structure, BCCM () structurally conforms at least partially to a surface contour of the anatomical structure for reciprocating any motion by the anatomical structure. Optical fiber () is at least partially embedded in the BCCM () for generating an encoded optical signal () indicative of a shape of the optical fiber () responsive to any SOS reciprocal motion by the BCCM () during an imaging of the anatomical structure. System () further employs a motion tracker () responsive to encoded optical signal () for periodically reconstructing the shape of optical fiber () with each change in the shape of optical fiber () representing motion by the anatomical structure.

Abstract:

The following relates generally to image segmentation. In one aspect, an image is received and preprocessed. The image may then be classified as segmentable if it is ready for segmentation; if not, it may be classified as not segmentable. Multiple, parallel segmentation processes may be performed on the image. The result of each segmentation process may be marked as a potential success (PS) or a potential failure (PF). The results of the individual segmentation processes may be evaluated in stages. An overall failure may be declared if a percentage of the segmentation processes marked as PF reaches a predetermined threshold.

International Classification:

G06T 7/20
G06T 7/38

Abstract:

The invention relates to a method of calculating a displacement of an object of interest comprising a step of calculating () a displacement model of said object of interest from adjacent images of a set of pre-acquired images of said object of interest, said displacement model reflects the position of said object of interest along the time. The method is characterized in that the method further comprises the following. A step of determining () a first sub-set of images (S) from said set of pre acquired images within one periodical time cycle of said set of pre-acquired images on the basis of the displacement model. A first step of identifying () a second sub-set of images (S) from newly-acquired images, wherein images in said second sub-set of images (S) are consecutive and have the same most similar image in said first sub-set of images (S), wherein a first set of similarity levels is determined by comparing a given image in said newly acquired images with each image of said first sub-set of images (S), and wherein said most similar image has the largest similarity level in said first set of similarity levels. A first step of selecting () a given image in said second sub-set of images (S) as a first reference image (I). A second step of identifying () a third sub-set of images (S) from said newly-acquired images, wherein images in said third sub-set of images (S) are consecutive and have the same most similar image in said first sub-set of images (S), wherein a set of similarity levels is determined by comparing a given image in said newly acquired images with each image of said first sub-set of images (S), and wherein said most similar image has the largest similarity level in said set of similarity levels. A second step of selecting () a given image in said third sub-set of images (S) as a second reference image (I). A step of calculating () the displacement between said second reference image (I) and said first reference image (I). The invention also relates to a corresponding system of displacement calculation.

Abstract:

The invention relates to a brachytherapy apparatus () for applying a brachytherapy to a living object. The brachytherapy apparatus comprises a planning unit () for determining a placing plan defining placing positions and placing times for one or several radiation sources within the living object and close to a target region. The placing plan is determined such that the placing times are within a treatment time window determined by a treatment time window determination unit (), wherein within the treatment time window a change of a spatial parameter of the living object caused by swelling is minimized. An adverse influence on the brachytherapy due to swelling can thereby be minimized, which improves the quality of the brachytherapy.
