  • Patent number: 10405828
    Abstract: The invention relates to location determination apparatus for determining a location of a first object (2) like a catheter within a second object (3) being, for example, the heart of a person. The first object comprises a first ultrasound unit, and a second ultrasound unit (5) is located outside the second object. A location determination unit determines the location of the first object within the second object based on ultrasound signals transmitted 5 between the first ultrasound unit and the second ultrasound unit. This allows determining the location of the first object within the second object reliably in a way which is an alternative to using a transmission of electrical signals for determining the location and which may lead to an improved accuracy of determining the location.

  • Publication number: 20190159752
    Abstract: An interventional instrument (30) having ultrasound sensors (S1, S2, S3, S4, . . . ) is tracked using an ultrasound imaging device (10) that acquires and displays a 2D ultrasound image of a visualization plane (18), and performs 2D ultrasound sweeps for a range of plane angles (?) obtained by rotating the ultrasound probe (12) and encompassing the visualization plane angle. For each ultrasound sensor, an optimal plane is found based on its emitted signal strength over the range of plane angles, and the ultrasound sensor is located in its optimal plane by analyzing the sensor signal as a function of the timing of the beams fired by the ultrasound probe. These locations in their respective optimal planes are transformed to a 3D reference space using a transform (42) parameterized by plane angle, and a visual indicator is displayed of spatial information (T, L) for the interventional instrument generated from the locations of the one or more ultrasound sensors in the 3D reference space.

  • Patent number: 10279194
    Abstract: The invention relates to a HDR brachytherapy system comprising an ultrasound sensor for being arranged at the location of a brachytherapy catheter (12), wherein the ultrasound sensor is adapted to generate an ultrasound signal based on ultrasound radiation, which has been sent by an ultrasound imaging device preferentially comprising a TRUS probe (40) and which has been received by the ultrasound sensor. The position of the ultrasound sensor is determined based on the generated ultrasound signal, and based on this position of the ultrasound sensor the pose and shape of the brachytherapy catheter and/or the position of a HDR radiation source are determined. This allows for a very accurate determination of the pose and shape of the brachytherapy catheter and/or of the position of the HDR radiation source, which in turn can lead to an improved HDR brachytherapy.

  • Publication number: 20180000446
    Abstract: A target biopsy system employing an ultrasound probe (20), a target biopsy needle (30) and a ultrasound guide controller (44). In operation, the ultrasound probe (20) projects an ultrasound plane intersecting an anatomical region (e.g. a liver). The target biopsy needle (30) include two or more ultrasound receivers (31) for sensing the ultrasound plane as the target biopsy needle (30) is inserted into the anatomical region. In response to the ultrasound receiver(s) (31) sensing the ultrasound plane, the ultrasound guide controller (44) predicts a biopsy trajectory of the target biopsy needle (30) within the anatomical region relative to the ultrasound plane. The prediction indicates the biopsy trajectory is either within the ultrasound plane (i.e., an in-plane biopsy trajectory) or outside of the ultrasound plane (i.e., an out-of-plane biopsy trajectory).
