An ultrasound training model which exhibits optically clear soft tissue-mimicking materials that are simultaneously acoustically scattering and self-healing to needle punctures. An exemplary embodiment is disclosed that comprises an embedded bone-mimicking spine model and a dual-purpose lid that may be used as a friction surface mat. Various embodiments of the training model materials are disclosed.

Ultrasound scanning surface apparatus and assembly

Systems and methods for anatomical identification using ultrasonic imaging and acoustic shadow detection methods are provided. At least some embodiments of the disclosure comprise the following steps: acquiring ultrasound image; detecting shadow region; extracting shadow profile; filtering shadow profile with matched filter; identifying anatomical landmarks within shadow; extracting features of anatomical landmarks; classifying anatomy, and determining with a high degree of confidence that the target anatomy is depicted in the image. A determination is made as to the degree of confidence that the target anatomy is depicted in the image. Conditionally, graphics indicating presence and position of target anatomy is displayed including disposition, location and orientation thereof.

An ultrasound imaging scan head includes a fluid chamber including a gearless voice-coil motor therein. The voice-coil motor mechanism includes a rigid mechanical assembly, capable of moving with the fluid chamber, having one or more transducer elements and motor windings. Within the fluid chamber are motor magnets physically separated from the rigid mechanical assembly. The ultrasound imaging scan head further includes an inductive position sensor and internal bladder wherein the one or more transducer elements are capable of moving within the fluid chamber when a current is passed through the motor windings in a presence of a magnetic field generated by the one or more motor magnets.

The position and orientation of an ultrasound probe is tracked in three dimensions to provide highly-accurate three-dimensional bone surface images that can be used for anatomical assessment and/or procedure guidance. The position and orientation of a therapy applicator can be tracked in three dimensions to provide feedback to align the projected path of the therapy applicator with a desired path for the therapy applicator or to provide feedback to align the potential therapy field of a therapy applicator with a target anatomical site. The three-dimensional bone surface images can be fit to a three-dimensional model of the anatomical site to provide or display additional information to the user to improve the accuracy of the anatomical assessment and/or procedure guidance.

Three-dimensional imaging and modeling of ultrasound image data

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.

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

Systems and methods for treating a blood clot include a catheter to be inserted into a patient. The catheter is used to deliver low stability microbubbles toward the blood clot in the patient. A thrombolytic agent is delivered toward the blood clot, and ultrasonic energy is applied to the microbubbles to vibrate the microbubbles.
