  • Patent number: 11576644
    Abstract: The invention relates to an interventional system comprising an introduction element (4) like a catheter for being introduced into an object (9), for instance, a person. A moving unit (2) like a robot moves the introduction element within the object, wherein a tracking image generating unit (3) generates tracking images of the introduction element within the object and wherein a controller (8) controls the tracking image generating unit depending on movement parameters of the moving unit, which are indicative of the movement, such that the tracking images show the introduction element. This control can be performed very accurately based on the known real physical movement of the introduction element such that it is not necessary to, for instance, irradiate a relatively large area of the object for ensuring that the introduction element is really captured by the tracking images, thereby allowing for a reduced radiation dose applied to the object.

  • Patent number: 11559281
    Abstract: An imaging system includes transmit circuitry, a transducer array with an array of capacitive micromachined ultrasonic transducer elements, a beamformer, a decoder and a display. The transmit circuitry includes a signal generator and at least one excitation coding scheme. The transmit circuitry combines an excitation signal generated by the signal generator with an excitation coding scheme of the at least one excitation coding scheme, generating a coded excitation signal. The array of transducer elements is excited with the coded excitation signal to emit ultrasound signals. The coding scheme does not introduce heating on the capacitive micromachined ultrasonic transducer elements. The array of ultrasonic transducer elements receives echo signals produced in response to the ultrasound signals interacting with structure and generates electrical signals indicative thereof.

  • Patent number: 11547277
    Abstract: A method of providing and processing an ultrasound capable endoscope assembly that uses an endoscope having a proximal and a distal end, and that has been used previously. The endoscope is cleansed to a level appropriate for re-use within a human body. The method also uses an unused ultrasound assembly, sealed in antiseptic packaging, and which includes a multiple signal pathway connector; an ultrasound transducer head including an ultrasound transducer; and a set of signal pathways, extending from the ultrasound transducer to the multiconductor electrical connector. In the method, the ultrasound assembly is to the endoscope, so that the set of signal pathways extends along the elongate body of the endoscope and the ultrasound transducer head is attached at the distal end. After use, the ultrasound assembly is detached from the endoscope and permanently disposed.
