MEDICAL OBJECT FOR ARRANGEMENT IN AN OBJECT UNDER EXAMINATION AND SYSTEM FOR SENSING A MEDICAL OBJECT

A medical object for arrangement in an object under examination includes an optical fiber. The optical fiber is configured to contact at least one light source optically. The medical object further includes multiple photoacoustic absorbers that are arranged in sections along a direction of longitudinal extension of the optical fiber and/or along a periphery of the medical object. The multiple photoacoustic absorbers are configured to be arranged at least in part in the object under examination. The optical fiber is configured to conduct an excitation light emitted by the at least one light source to the multiple photoacoustic absorbers. The multiple photoacoustic absorbers are configured to be excited by the excitation light for the photoacoustic emission of ultrasound.

MEDICAL NEEDLE GUIDANCE SYSTEM
20220370050 · 2022-11-24 · ·

An insertion tool guide for a medical procedure like a biopsy. The tool guide includes (a) a frame configured to be adjoined to a medical image modality and maintain an insertion angle aligned with a plane of view generated by the medical image modality; (b) a guide body having an adjustable channel configured to receive and translate an insertion tool; (c) a main channel defined by the frame configured to allow the guide body and the insertion tool to rotate within a plane of movement; (d) a guide channel formed along one side of the frame configured to allow the guide body to translate along its length; and (e) a peg extending from the guide body and through the guide channel to secure the guide body within the frame. The guide body is configured to rotate about an axis defined by the peg.

Apparatus and methods to create and maintain an intra-atrial pressure relief opening

The present disclosure relates to a method and a device for treating heart failure by normalizing elevated blood pressure in the left and right atria of a heart of a mammal. The present disclosure includes methods for creating and maintaining an opening in the atrial septum. Tools for making an opening and enlarging the opening are also disclosed. Use of the techniques and tools described herein prolongs the patency of an intra-atrial pressure relief opening.

Photoacoustic image generation apparatus

A photoacoustic image generation apparatus includes: a puncture needle that generates photoacoustic waves; an ultrasound probe that detects the photoacoustic waves and reflected ultrasonic waves reflected by the transmission of ultrasonic waves; a processor that generates a color Doppler signal of a region of interest as a color Doppler measurement target, generates a photoacoustic image on the basis of the photoacoustic waves, and detects the position of a tip portion of the puncture needle on the basis of the photoacoustic image; and a controller that sets the region of interest such that the position of the tip portion of the puncture needle and a center position of the region of interest are separated from each other by a predetermined distance and sets the region of interest, following the movement of the tip portion of the puncture needle, in a state in which the distance is maintained.

Transperineal imaging-guided prostate needle placement

Prostate biopsy systems are provided that include a 3D ultrasound probe support configured to receive an ultrasound probe for transperineal imaging. One or more template grids can have a plurality of apertures extending therethrough to receive and guide a biopsy needle along a trajectory associated with respective apertures when the template grid is fixed to the support and the biopsy system is positioned in the perineal area of a patient. Patient-specific template grids can also be developed and produced. This system enables fully transperineal prostate biopsy (i.e. both imaging and needle placement are perineal) and eliminates the need for an external racking device for image fusion as well as needle tracking. In addition, it reduces the infection risk associated to transrectal approach.

Three-dimensional imaging and modeling of ultrasound image data

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.

Medical image processing apparatus, medical image processing method, and storage medium

A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain a measurement value related to the shape of a heart valve in medical image data. The processing circuitry is configured to cause a display to display a numerical value related to the shape of an artificial valve to be placed for the heart valve.

ACQUIRING IMAGE DATA OF A BODY PART
20230056121 · 2023-02-23 ·

A method for acquiring image data of a body part of a patient by means of a ultrasonography device comprising the following steps: providing a transducer of the ultrasonography device, said transducer comprising a first orientation sensor; attaching a second orientation sensor to the skin of the patient above the body part; detecting the orientation of the first orientation sensor relative to the second orientation sensor and verifying, whether the relative orientation corresponds to a target value; and acquiring image data of the body part, once the relative orientation corresponds to the target value.

AN ULTRASOUND SYSTEM
20220361961 · 2022-11-17 ·

The invention provides an ultrasound system comprising an ultrasound probe, adapted to transmit and receive ultrasound signals, and an interventional device for insertion into a vessel of a subject. The interventional device includes an ultrasound transducer adapted to acquire a first set of ultrasound data at a first ultrasound frequency, wherein the first set of ultrasound data relates to flow data. The ultrasound system is further adapted exchange a second set of ultrasound data between the ultrasound probe and the interventional device at a second ultrasound frequency different from the first ultrasound frequency, wherein the second ultrasound data relates to interventional device positioning data.

Non-Metallic Ultrasound-Detectable Markers

Markers (e.g., treatment site markers, biopsy site markers) are composed of a non-metallic material having a composition and/or other features or characteristics such that the markers will generate twinkling artifacts when imaged with ultrasound. In this way, the composition of the markers enables their detection and localization using ultrasound. The markers are generally composed of non-metallic materials that enhance the twinkling artifact.
