Embodiment Construction

[0016] These principles provide systems and methods for deriving real-time shape information from medical devices or other objects tracked in vivo, eg, with fiber optic shape sensing or with electromagnetic position and orientation measurement systems or other similar positioning platforms. The shape information can be used to dynamically adjust the frame rate or other imaging characteristics or functions of an imaging system, such as an X-ray (fluoroscopy) system. Adjusting the frame rate, e.g., to minimize x-ray exposure of the physician and patient, while providing accurate visualization of the device, e.g., in a minimally zoomed-out view through automatic positioning of the gantry based on positioning information derived from tracked objects . Frame rates can be adjusted to trade off temporal versus spatial resolution during magnetic resonance (MR) image acquisition and reconstruction. If the device is moved only a small distance due to the acquisition of a previous fluor...

Abstract

A system and method for adaptive imaging include a shape sensing system (115, 117) coupled to an interventional device (102) to measure spatial characteristics of the interventional device in a subject. An image module (130) is configured to receive the spatial characteristics and generate one or more control signals in accordance with the spatial characteristics. An imaging device (110) is configured to image the subject in accordance with the control signals.

Description

technical field [0001] The present disclosure relates to medical imaging, and more particularly, to diagnostic or interventional control systems for optimization or adjustment of imaging characteristics, such as imaging views, acquisition system rates, and the like. Background technique [0002] There are various medical procedures that involve the insertion of devices into the human body under X-ray guidance. These procedures include guiding catheters to perform vascular procedures, such as stent placement; and guiding needles to perform tissue biopsies and ablation. X-ray fluoroscopy is important in identifying anatomical landmarks at known locations relative to the device target location. With X-ray fluoroscopy, a physician can acquire a single image or multiple images (eg, as a video) in rapid succession. [0003] With multiple images in quick succession, there is a risk that the physician and patient will be exposed to X-rays far greater than is necessary to actually ...
