  • Publication number: 20240090869
    Abstract: The present discussion relates to structures and devices to facilitate application of an ultrasound therapy beam to a target anatomic region in a replicable manner. In certain aspects, adjustable positioning structures are described that allow a general probe positioning structure to be configured for a specific patient in a manner that allows the device to be used repeatedly to target the anatomic region, even when in non-clinical settings. In other aspects, a probe positioning structure is fabricated that is specific to a respective patient anatomy, such that use of the probe positioning structure provides repeatable targeting of the target anatomic region, even when in non-clinical settings.

  • Publication number: 20230414972
    Abstract: The present discussion relates to structures and devices to facilitate application of an ultrasound therapy beam to a target anatomic region in a replicable manner. In certain aspects, an alignment controller may be used to analyze images generated by an ultrasound transducer. The alignment controller may then send a communication to indicate the energy application device is positioned to provide therapy to the target region, or if the device needs to be repositioned. The alignment control of the energy application device provides guided repeatable targeting of the target anatomic region, even when in non-clinical settings.
