The present invention provides an image display method with which a structure of an imaging object can be easily understood on the basis of volume data. An image display method according to an aspect of the present invention includes obtaining photoacoustic image data, generating a first photoacoustic image corresponding to a first spatial region on the basis of photoacoustic image data and a second photoacoustic image corresponding to a second spatial region having a different thickness in a viewing direction of rendering from a thickness of the first spatial region and having a spatial region overlapped with the first spatial region on the basis of the photoacoustic image data, and generating and displaying a parallel image in which the first photoacoustic image and the second photoacoustic image are arranged side by side.

For deploying a stent at a coronary ostium, an integrated intravascular ultrasound (IVUS) ostial stent delivery apparatus can include a balloon catheter and an elongate shaft defining (1) a longitudinal inflation lumen and (2) a longitudinal IVUS lumen. A balloon can be located at and about the distal shaft portion and inflated with the inflation lumen. The shaft further defines a longitudinal guidewire lumen, extending at least through the distal shaft portion underlaying the balloon for at least a length of the balloon along the shaft. The IVUS lumen can include removable IVUS ultrasound imaging transducer with a signal conduit to external processing and display componentry. The imaging can help ensure proper stent location before placement and deployment, or for post-placement and stent deployment confirmation, without requiring removal of the stent delivery device to deploy a separate IVUS imaging probe.

Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system comprising a processor circuit configured to receive, from an ultrasound transducer array, a plurality of images of a patient body at different imaging planes; determine a first imaging plane based on a first image of the plurality of images by applying a first predictive network, wherein a second image of the plurality of images is based on the first imaging plane, and wherein the second image includes an imaging view of at least one of an anatomy of the patient body or a medical device within the anatomy; apply a second predictive network to the second image to generate segmentation data; and output, to a display, a displayed image including an indication of a first portion of the at least one of the anatomy or the medical device based on the segmentation data.

Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system, comprising an intraluminal imaging device comprising a flexible elongate member configured to be positioned within a patient's body lumen and an ultrasound transducer array coupled to the flexible elongate member, the ultrasound transducer array configured to transmit ultrasound energy into the body lumen and to receive ultrasound echoes associated with the body lumen; and a processor circuit in communication with the intraluminal imaging device and configured to receive, from the ultrasound transducer array, first signal data corresponding to the received ultrasound echoes; transform the first signal data based on a first parameter associated with a reference tissue characterization data; characterize the transformed first signal data based on the reference tissue characterization data; generate a first image of the body lumen based on the characterization; and output, to a display in communication with the processor circuit, the first image.

A probe with a blood circulation sensor and a force or pressure sensor is placed against a patient. One part of the probe applies a force to another part of the probe which is pressed against the patient at one or more locations. The variation of a measure of blood circulation is recorded as a function of the applied pressure, thereby giving the operator a specific knowledge of the Tissue Perfusion Pressure (TPP), a measure of circulatory health, at each location.

Implementations described and claimed herein provide systems and methods for managing one or more patients. In one implementation, an imaging window is determined based on a location of a probe. A primary image cross-section for the imaging window is identified for the imaging window. At least one image is generated along the primary image cross-section using patient data captured using the probe. The at least one image is compared to an expected image contour scaffold of the primary image cross-section. The probe is commanded to fine-tune an imaging plane based on the comparison until the at least one image matches the expected image contour scaffold of the primary image cross-section.

Techniques for placing implantable electrodes to treat sleep apnea, and associated devices, systems, and methods are disclosed herein. A representative method includes percutaneously implanting one or more signal delivery devices, each at or near a respective target signal delivery location in a patient. Each signal delivery device can include one or more electrodes, and individual ones of the electrodes can be positioned to produce a net positive protrusive motor response of the patient's tongue. The representative method further includes providing power to one or more of the electrodes from a wearable power source to cause the electrode(s) to deliver an electrical signal to the respective target signal delivery location(s) to produce the net positive protrusive motor response.

According to various embodiments, there is provided a device including a processor configured to control a robotic system to autonomously position a transducer at a plurality of locations adjacent a subject's skull and to autonomously locate a window on the subject's skull within which an artery can be located, from which artery a signal can be returned to the transducer, the signal having an energy level exceeding a predefined threshold.
