    摘要： The invention is a system for measuring the true dimensions and orientation of objects in a two dimensional image. The system is comprised of a ruler comprising at least one set of features each comprised of two or more markers that are identifiable in the image and having a known spatial relationship between them and a software package comprising programs that allow extension of the ruler and other objects in the two dimensional image beyond their physical dimensions or shape. The system can be used together with radiographic imagery means, processing means, and display means to take x-ray images and to measure the true dimensions and orientation of objects and to aid in the identification and location of a surgery tool vs. anatomy in those x-ray images. The invention provides a method of drawing and displaying on a two dimensional x-ray image measurements of objects visible in said image, graphical information, or templates of surgical devices.

    摘要： A method of calibrating a measurement of electromagnetic (EM) signals. The method comprises separating at least one reference signal component from an EM signal, delaying at least one of the EM signal and the at least one reference signal component, extracting the EM signal after an interaction with a target object and the at least one reference signal component after at least one interaction with at least one reference element from different time slots in a reception, and calibrating a measurement of the interacted EM signal by a signal analysis of the extracted and interacted at least one reference signal component.

    摘要： Disclosed is a method for generating a panoramic image of a region of interest (ROI) which is larger than a field of a view of a radiation based imaging device, comprising, positioning markers along the ROI, acquiring a set of images along the ROI, wherein the acquired images have at least partially overlapping portions, aligning at least two separate images by aligning a common marker found in both images and compensating for a difference between a distance from a radiation source to the marker element and the distance from the radiation source to a plane of interest.
