  • Patent number: 10448927
    Abstract: A system and method for identifying a characteristic of a region of a subject, such as whether a region is cancerous, which includes an ultrasonic imaging device that acquires a first and second set of time series data from a region of a subject during a first and second time period. The system includes a comparison device (120) that receives first and second sets of time series data (116, 118) and computes differential data (119) therebetween at one or more features. A processing device (130) receives the differential data and inputs the differential data into a classifier (132) trained with reference differential data concerning the one or more features as well as an identification of the ground truth concerning the region. A determination device (136) is configured to determine whether the region contains the characteristic based on an output from the classifier.

  • 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: 20180330802
    Abstract: The present system is configured to generate adaptive, optimal, intelligent questionnaires for diagnosing depression, ADHD, and/or other medical conditions. The system is configured to train a prediction model based on a database of previously asked and answered questions related to various medical conditions. A questionnaire for a specific patient is determined from the questions in the database based on caregiver supplied criteria including a number of questions the questionnaire should have and a quality metric indicating a desired level of relatedness of the questions in the questionnaire to the patient's medical condition. If the patient decides to not answer one or more questions for any reason, another subset of questions are suggested.
