Problems solved by technology

[0004] However, since most existing interventional and procedural devices are relatively incompatible with ultrasound imaging, imaging such devices using ultrasound is often difficult
In particular, effects such as shadows, reflections, and acoustic artifacts can obscure the device to some extent, making it difficult to identify the device in ultrasound images
In addition, when the device is not completely within the restricted field of view (FoV) of ultrasound imaging, the device may only be partially captured, making it difficult to correctly interpret the image and obtain an optimal guidance and treatment field of view

Embodiment Construction

[0060] figure 1 An exemplary apparatus 1 for supporting a medical procedure as described herein is shown. The apparatus comprises an input unit 2 for receiving first image data and second image data, such as X-ray medical image data from a C-arm imaging device 7 and ultrasound medical image data from an ultrasound probe 6 . Image data are acquired during a procedure on a patient 5 lying on a support 4 . According to an example further described herein, a processing unit 3 is provided for processing image data and identifying a device of interest.

[0061] Optionally, the device is part of an imaging system, eg an ultrasound imaging system also comprising the ultrasound probe 6 . In this case, for example, the device may be configured as or form part of an ultrasound console. Alternatively, a computer program product may be provided for execution by a processing unit of an ultrasound console.

[0062] Alternatively, the apparatus may be part of a C-arm interventional X-ray ...

Abstract

The present invention relates to supporting an interventional procedure involving a device, such as a cardiovascular procedure. First and second image data acquired using different imaging apparatus, for example X-ray and ultrasound image data, are co-registered. A device is firstly identified in 2D X-ray images; corresponding identification information is then used to generate a view from 3D ultrasound image data that includes a cross-section of the device to be identified subsequently. Following the identification, a 3D position and orientation of the device are available. Such information may advantageously be used in setting up optimal ultrasound views for image-based guidance of the ongoing procedure.

Description

technical field [0001] The invention relates to an apparatus for supporting a medical procedure involving a device, an imaging system comprising such an apparatus, a method for tracking a device in medical image data, a computer program product and a computer-readable device storing such a computer program product. medium. Background technique [0002] Various medical imaging systems are used to acquire images of anatomical structures, such as the cardiovascular system. These images can be used to provide feedback to clinicians during medical procedures, such as advanced minimally invasive procedures or interventions performed in the operating room or catheterization laboratory (cathlab). [0003] For certain medical interventions in the cardiac field, X-ray fluoroscopy and / or ultrasound imaging may be used. For example, ultrasound imaging (or echo imaging) such as 3D TEE or ICE is the modality of choice for many upcoming transcatheter structural heart interventions (SHI)....
