    摘要: Various methods and systems are provided for collision avoidance in cone-beam computed tomography (CT) systems. In one embodiment, a method for an imaging apparatus comprises calculating a likelihood of a collision between the imaging apparatus and a subject and/or its support based on a model of the subject, performing a scan of the subject responsive to the likelihood below a threshold, and not performing the scan otherwise. In this way, collisions between the patient and the imaging apparatus can be avoided.

    摘要: In the present invention, a system and associated method is provided for image-guided navigation during a medical procedure. The system includes a movable gantry having an X-ray source, an X-ray detector and a laser disposed on the detector offset from the area of the detector receiving the beam from the source, a movable table and a system controller operably connected to the gantry, the X-ray source, the X-ray detector, the laser and the table. In the method, the controller determines an optimal trajectory for the insertion of an interventional device into the body to intersect the target, positions the gantry to locate the laser at a point where a laser beam is emitted from the laser along the optimal trajectory outside of the X-ray beam, and takes additional images during the procedure to show the position of the interventional device in the body as compared with the optimal trajectory.

    摘要: Systems and methods for surgical tool navigation, include a movable gantry. A light emitting device is connected to the movable gantry. A range meter connected to the gantry. The distance meter measures a distance between the light emitting device and a surface. In a method of surgical tool navigation, the light emitting device projects light on the surface. The range meter detects the light and measures the distance between the light emitting device and the surface.

    摘要: A system for imaging includes a gantry movable relative to a subject. A source is configured to emit radiation during an imaging procedure. A detector is configured to receive attenuated radiation from the source during an imaging procedure, at least one of the source and the detector movably secured to the gantry by an adjustable joint. An imaging controller is operably connected to at least the gantry and to the adjustable joint, wherein the gantry controller receives a priori patient information and imaging system geometry information, the imaging controller determines an imaging geometry and operates the gantry and the adjustable joint to vary a source to image-receptor distance (SID) according to the imaging geometry.

    摘要: A workflow assistance system for image guided surgical procedures includes an interventional imaging system. The interventional imaging system operates to move relative to a patient and to acquire interventional images during a surgical procedure. A surveillance system is arranged about a surgical suite and produces surveillance data. A workflow controller processes the surveillance data to identify locations of clinicians, the patient, the interventional imaging system, and medical equipment within the surgical suite and provide operational commands to the interventional imaging system based upon the surveillance data.
