Localization of imaging target regions and associated systems, devices and methods

摘要

Handheld ultrasound imaging devices for identification of target regions are generally described. Medical ultrasound is a popular medical imaging modality primarily used for diagnostic imaging of soft tissue but also for interventional procedures such as guidance of a needle or catheter placement. Examples include diagnostic imaging of organs, such cardiac or liver structures. Common interventional procedures that rely on ultrasound guidance are central line placement and guidance of nerve blocks, both of which are high volume procedures in certain hospital settings such as the intensive care unit (ICU). Handheld ultrasound imaging devices with integral display screens and improve portability are described, along with systems and methods for orienting displayed ultrasound images so as to improve their usefulness in guiding interventional procedures.
