System and method for non-invasive sonication, through at least one of enamel and dentin, of a root-canal system of a target tooth with an externally delivered ultrasound beam, to disinfect the root-canal system while blocking a nerve associated with the tooth and removing a need for radiography to confirm the results of endodontics. The tooth does not have a physical access opening to the root canal system. When focused, the beam is oriented to expose the root-canal system to the ultrasound within the confocal range of the beam such as to concentrate the ultrasound energy within the root-canal system and to avoid irradiating teeth that are immediately adjacent to the target tooth.

A workflow is disclosed to accurately register ultrasound imaging to co-modality imaging. The ultrasound imaging is segmented with a convolutional neural network to detect a surface of the object. The ultrasound imaging is calibrated to reflect a variation in propagation speed of the ultrasound waves through the object by minimizing a cost function that sums the differences between the first and second steered frames, and compares the first and second steered frames of the ultrasound imaging with a third frame of the ultrasound imaging that is angled between the first and second steered frames. The ultrasound imaging is temporarily calibrated with respect to a tracking coordinate system by creating a point cloud of the surface and calculating a set of projection values of the point cloud to a vector. The ultrasound imaging, segmented and calibrated, is automatically registered to the co-modality imagine.

A method for elasticity ultrasound imaging , the method comprising:acquiring, with an ultrasound system, first ultrasound data for a three-dimensional region, the first ultrasound data comprising voxels representing different locations distributed along three axes in the three-dimensional region at a first time;acquiring, with the ultrasound system, second ultrasound data for the three-dimensional region, the second ultrasound data comprising voxels representing the different locations distributed along the three axes in the three-dimensional region at a second time different from the first time;identifying an anatomical landmark of the three-dimensional region and represented in the first and second ultrasound data;determining motion of the anatomical landmark from the first time to the second time;estimating elasticity in the three-dimensional region from the first and second ultrasound data;motion correcting in the estimating of elasticity in the three-dimensional region from the first and second ultrasound data, the motion correcting being a function of the motion of the anatomical landmark; anddisplaying a three-dimensional representation of the elasticity in the three-dimensional region.2. The method of wherein acquiring the first and second ultrasound data comprises scanning the three-dimensional region while the three-dimensional region is subjected to a change in tissue deformation.3. The method of ...

A method of acquiring ultrasound of a patient's knee includes obtaining a digital picture of a patient's knee with a digital camera. The method further includes applying instructions to the processor to identify the position of the patient's knee relative to a known datum based on an algorithm and the digital picture. A scan path is created about the patient's knee based on the position of the patient's knee. Instructions are provided from a robotic processor to robotically move an ultrasound probe along the scan path. 1. An apparatus comprising:a digital camera providing a digital picture of a patient's knee;a processor receiving instructions to identify the position of the patient's knee from the digital picture;the processor creating a scan path about the patient's knee;a robotic arm supporting an ultrasound probe and receiving instructions from the processor to move the ultrasound probe along the scan path.2. The apparatus of including a positioning system providing instructions to a patient support to robotically position the patient's knee in a given orientation.3. The apparatus of claim 2 , wherein the positioning system moves the patient's knee from a first orientation to a second different orientation.4. The apparatus of claim 2 , wherein the first orientation is a straight orientation and the second orientation is a bent orientation.5. The apparatus of claim 2 , wherein the positioning system rotates the patient's leg about a longitudinal axis of a lower portion of the patient's leg.6. The apparatus of claim 1 , wherein the scan path extends substantially about an outer portion of patient's knee including a patella region and a popliteal foss region of the patient's knee.7. The apparatus of including an input device for a medical operator to identify the region of interest of the patient's knee joint for ultrasound imaging.8. The apparatus of claim 1 , wherein the scan path is updated during movement of the ultrasound probe and acquisition of ultrasound ...

Various systems and methods for imaging soft oral tissue via an ultrasound oral imaging instrument are disclosed. The ultrasound oral imaging instrument can be coupled to an ultrasound probe that includes an ultrasonic transducer for generating ultrasound pulses. The instrument can include an actuator couplable to the ultrasound probe. The actuator can move the ultrasound probe as the as the ultrasound probe emits ultrasound pulses to image tissue against which the ultrasound probe is directed. The instrument can be utilized to image soft oral tissue by applying an acoustic coupler to the soft oral tissue to be imaged or the ultrasound probe, moving the ultrasound probe along the soft oral tissue to captured two-dimensional slices or images of the tissue, and then reconstructing three-dimensional images from the two-dimensional slices. 1. An ultrasound oral imaging instrument comprising:an ultrasound probe comprising an ultrasonic transducer;an actuator coupled to the ultrasound probe, the actuator configured to move the ultrasound probe between a first position and a second position; and cause the ultrasonic transducer to emit ultrasound pulses through the ultrasound probe; and', 'cause the actuator to move the ultrasound probe between the first position and the second position as the ultrasound probe emits the ultrasound pulses., 'a control circuit coupled to the ultrasonic transducer and the actuator, the control circuit configured to2. The ultrasound oral imaging instrument of claim 1 , further comprising:a housing enclosing the actuator and the control circuit; anda shaft connecting the ultrasound probe to the housing;wherein the actuator is configured to drive the shaft to move the ultrasound probe between the first position and the second position.3. The ultrasound oral imaging instrument of claim 2 , wherein the ultrasound probe is removably attachable to the shaft.4. The ultrasound oral imaging instrument of claim 2 , further comprising a power source ...
