Embodiment Construction

[0016] The present disclosure describes methods and systems for adaptive image-guided medical interventions using a surface attached to the patient's body at the interventional insertion site and / or near the target anatomy of interest. Chip optical shape sensing. The methods and systems may be used in conjunction with one or more imaging modalities, such as computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, fluoroscopy, and the like.

[0017] figure 1 The optical sensing system 100 is schematically illustrated. The optical sensing system 100 has an optical interrogation console 101 optically connected to at least one optical sensor device 102 and electrically connected to a three-dimensional orientation reconstructor 103 . Optical interrogation console 101 sends optical interrogation signals to optical wires 104 embedded within or on substrate material 105 to form optical sensor device 102 . The optical signal travels out to the optical sensor device 10...

Abstract

A method and system for generating imaging data during a medical intervention is provided. An external optical sensor is attached to the patient's body and includes at least one external orientation fiber core configured to measure the orientation of the external optical sensor relative to a reference point. The external optical sensor is interrogated during the medical intervention to generate external sensor orientation information. Said information is used to estimate the orientation of said external optical sensor during said medical intervention, which is then displayed.

Description

technical field [0001] The present application relates generally to methods and systems for use in the field of medical imaging, and in particular to adaptive image-guided medical interventions. An "intervention" in this context is the insertion of one or more medical instruments into a patient in order to perform a medical procedure. Medical instruments can be such as needles, mechanical scalpels (lancets), laser scalpels, endoscopes, microscopic imaging probes, surgical staplers, retractors, cautery devices (electrical or optical), catheters, chisels , clamps, probes, trocars, scissors, etc. During many interventional procedures, a physician will use more than one medical device. Background technique [0002] Such medical interventions are often performed in conjunction with preoperative and / or intraoperative imaging scans of the patient to guide instrument manipulation during the procedure. Preoperative or scout volumetric imaging performed with modalities such as comp...
