  • Publication number: 20160183910
    Abstract: The invention relates to a system and method in which a Foley catheter (70) or other medical tool which is equipped with ultrasound (US) sensor(s) (72) is inserted into the prostatic urethra. Based on analysis of the US signal received by these US sensors (72) as the US beams from a transrectal US (TRUS) probe (40) or other ultrasound probe sweep the field of view, it is possible to precisely detect and track these US sensors (72) in the same frame of reference as the TRUS images, thereby precisely delineating the Foley catheter and the course of the prostatic urethra. During the procedure, before each seed is dropped, the delivered dose to the prostatic urethra can be computed based on real-time tracking and segmentation of prostatic urethra and dose radiation based on previously dropped seeds and if necessary, the procedure can be re-planned automatically.

  • Publication number: 20160143615
    Abstract: The invention relates to an imaging apparatus (24) for imaging an introduction element (17) like a needle or a catheter for performing a biopsy or a brachytherapy. The introduction element (17) comprises at least one ultrasound receiver (21) arranged at a known location thereof. An ultrasound probe (12) for being inserted into a living being (2) emits ultrasound signals for acquiring ultrasound data of an inner part (19) of the living being (2). A first tracking unit (3) tracks the location of the introduction element (17) based on a reception of the emitted ultrasound signals by the at least one ultrasound receiver (21), an imaging unit (4) generates an indicator image showing the inner part (19) and an indicator of the introduction element (17) based on the tracked location, and a display (5) displays the indicator image. This allows receiving a feedback about the location of the introduction element (17).

  • Publication number: 20160098621
    Abstract: A method for multi-modal tissue classification of an anatomical tissue involves a generation of a tissue classification volume (40) of the anatomical tissue derived from a spatial registration and an image extraction of one or more MRI features of the anatomical tissue and one or more ultrasound image features of the anatomical tissue. The method further involves a classification of each voxel of the tissue classification volume (40) as one of a plurality of tissue types including a healthy tissue voxel and an unhealthy tissue voxel.

  • Publication number: 20160078633
    Abstract: A method for a mesh segmentation and a mesh registration involves an extraction of a preoperative anatomical mesh (51) from a preoperative anatomical image (50) based on a base topology of an anatomical mesh template (40), an extraction of an intraoperative anatomical mesh (61) from an intraoperative anatomical image (60) based on a preoperative topology of the preoperative anatomical mesh (51) derived from the base topology of an anatomical mesh template (40), and a registration of the preoperative anatomical image (50) and the intraoperative anatomical image (60) based on a mapping correspondence between the preoperative anatomical mesh (51) and the intraoperative anatomical mesh (61) established by an intraoperative topology of the intraoperative anatomical mesh (61) derived from the preoperative topology of the preoperative anatomical mesh (51).

  • Publication number: 20160030130
    Abstract: The invention relates to an imaging apparatus (24) for imaging an introduction element (17) like a needle or a catheter for performing a brachytherapy or a biopsy. A tracking unit (3, 4) tracks the location of the introduction element within a living being (2), an imaging unit (6) like an ultrasound imaging unit generates an image showing an inner part of the living being, which includes the tracked location of the introduction element, based on the tracked location, and a display (7) displays the image. During the brachytherapy or biopsy the display can always show the introduction element, without requiring a manual control. For instance, it is not necessary that a physician manually controls the position and image plane of the imaging unit. This allows for an accurate and fast insertion of the introduction element into the living being such that a target region is reliably reached.

  • Patent number: 9240032
    Abstract: A method, system, and computer program product are provided for performing a multi-modal deformable imaging registration between two different modalities for which a functional dependency is missing or very difficult to identify. The method provides a nonlinear mapping between every pair of points in the two image modalities by calculating the nonlinear mapping for only a limited number of identifiable landmarks within the two modalities and a statistical deformation model of the structure of interest.

  • Publication number: 20150342572
    Abstract: A method and system track a location of an object while the object is disposed within a region of interest within biological tissue, the location of the object being determined with respect to a tracking coordinate frame; generate acoustic images of the region of interest, the acoustic images being generated with respect to an acoustic image coordinate frame which is different from the tracking coordinate frame; transform the location of the object from the tracking coordinate frame to the acoustic image coordinate frame; and automatically adjust at least one image resolution parameter of the acoustic images in response to the location of the object with respect to the acoustic image coordinate frame.

  • Publication number: 20150306426
    Abstract: The invention relates to an assisting apparatus for assisting in performing brachytherapy. The position of an introduction element (17) like a catheter is tracked particularly by using electromagnetic tracking, while a group of seeds is introduced into a living object (2). This provides a rough knowledge about the position of the seeds within the object. An ultrasound image showing the group is generated depending on the tracked position of the introduction element and, thus, depending on the rough knowledge about the position of the seeds, in order to optimize the ultrasound visualization with respect to showing the introduced seeds. Based on this optimized ultrasound visualization the position of a seed of the group is determined, thereby allowing for an improved determination of seed positions and correspondingly for an improved brachytherapy performed based on the determined positions.
