The following relates generally to systems and methods of trans-esophageal echocardiography (TEE) automation. Some aspects relate to a TEE probe with ultrasonic transducers on a distal end of the TEE probe. In some implementations, if a target is in a field of view (FOV) of the ultrasonic transducers, an electronic beam steering of the probe is adjusted; if the target is at an edge of the FOV, both the electronic beam steering and mechanical joints of the probe are adjusted; and if the target is not in the FOV, only the mechanical joints of the probe are adjusted.

A telesurgical mentoring platform with a wheeled base, a lower rack mounted on the base, an upper rack extending vertically from the lower rack, a compactly foldable articulated arm that is configured to extend horizontally outward away from the upper rack and configured to connect to a connector piece holding an end effectuator at its distal end, a tablet personal computer; the console configured to be readily mobilized on the floor of an existing operating room and is capable of providing a connectivity point for communication, audiovisual, and data transfer services in an operating room.

A system is provided for augmenting a three-dimensional (3D) model of a heart to indicate the tissue state. The system accesses a 3D model of a heart, accesses two-dimensional (2D) images of tissue state slices of the heart, and accesses source location information of an arrhythmia. The system augments the 3D model with an indication of a source location based on the source location information. For each of a plurality of the tissue state slices of the heart, the system augments a 3D model slice of the 3D model that corresponds to that tissue state slice with an indication of the tissue state of the heart represented by the tissue state information of that tissue state slice. The system then displays a representation of the 3D model that indicates the source location of the arrhythmia and the tissue state of the heart.

Certain embodiments describe a system, method, and apparatus for ultrasound imaging. For example, the system can include a probe comprising a transducer configured to transmit or receive ultrasound waves. The system can also include a display communicatively coupled to the probe and one or more processors. The one or more processors cause the ultrasound system to detect, using the probe, one or more markings of a membrane located on a skin of a patient. The ultrasound system is also caused to determine position of the probe based on the one or more markings. In addition, the ultrasound system is caused to render on the display an indication of the position of the probe.

A patient monitoring system includes: a biomedical sensor including: a transducer configured to produce a signal corresponding to a biological function; a sensor converter configured to convert the signal to a converted signal; and a transmitter configured to produce a communication, based on the converted signal, that is indicative of one or more values of the biological function, and to send the communication wirelessly; and a base station including: a receiver configured to receive the communication wirelessly and to produce a receiver output signal; a base station interface configured to produce a base station output signal indicative of the one or more values of the biological function; and at least one output port to receive the base station output signal and configured to be hard-wire connected to a display that is configured to display information indicative of the biological function.

A downloadable navigator for a mobile ultrasound unit having an ultrasound probe, implemented on a portable computing device. The navigator includes a trained orientation neural network to receive a non-canonical image of a body part from the mobile ultrasound unit and to generate a transformation associated with the non-canonical image, the transformation transforming from a position and rotation associated with a canonical image to a position and rotation associated with the non-canonical image; and a result converter to convert the transformation into orientation instructions for a user of the probe and to provide and display the orientation instructions to the user to change the position and rotation of the probe.

A catheter-based imaging system comprises a catheter having a telescoping proximal end, a distal end having a distal sheath and a distal lumen, a working lumen, and an ultrasonic imaging core. The ultrasonic imaging core is arranged for rotation and linear translation. The system further includes a patient interface module including a catheter interface, a rotational motion control system that imparts controlled rotation to the ultrasonic imaging core, a linear translation control system that imparts controlled linear translation to the ultrasonic imaging core, and an ultrasonic energy generator and receiver coupled to the ultrasonic imaging core. The system further comprises an image generator coupled to the ultrasonic energy receiver that generates an image.

Apparatuses, systems, and methods of monitoring lesion formation using one-dimensional echograms are disclosed. In certain aspects, lesion formation progress is monitored using the intensity of reflectors in successive echograms during ablation. In another aspect, lesion formation progress is monitored based upon actual or apparent movement of acoustic reflectors before and after ablation. In still another aspect, the presence or absence of resonant microbubbles known to populate forming lesions are used to provide feedback on lesion formation. A lesion analysis processor can be programmed to determine lesion formation progress using any of the foregoing approaches, either alone or in various combinations.

An interposer with a spring on a surface of the interposer is disclosed. The spring may apply a force to a surface of a component adjacent to the interposer. The interposer may be secured to the surface by a fastener. The fastener may be offset from the center of the interposer. The fastener may be a fulcrum of a lever including the interposer and the spring. The spring may cause a portion of the interposer on the other side of the fastener from the spring to apply an increased amount of pressure to the surface to which the interposer is secured. A transesophageal exam ultrasound probe including an interposer is disclosed.

Examples disclosed herein relate to determining a power difference in sensor signals. Examples include a first sensor to transmit a first ultrasonic signal into a pregnant woman and to receive a second ultrasonic signal; and a second sensor to transmit a third ultrasonic signal into the pregnant woman and to receive a fourth ultrasonic signal. A processing resource determines a first power difference of the first sensor according to a difference between respective powers of the first ultrasonic signal and the second ultrasonic signal and is to determine a second power difference of the second sensor according to a difference between respective power of the third ultrasonic signal and the fourth ultrasonic signal. In examples, the processing resource is to determine a relative location of the fetal heart according to a comparison of the first power difference and the second power difference.
