Abstract: 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.

Abstract: The present invention includes methods, apparatuses, assemblies, circuits and systems for assessing, estimating and/or determining relative distances/positions, alignment, orientation and angles of rotation of a portion of a bone and between two or more portions of a bone, e.g. a fractured bone. According to some embodiments of the present invention, there may be provided a reference object (e.g. a reference grid), which reference object may include an array of reference markings visible in a radiographic image. The reference object may be used in conjunction with one or more radiographic imaging devices and image processing circuitry to facilitate determination of a 3D position and orientation of points within images acquired by the imaging devices from different angles and spatial relationships between these points.

Abstract: The present invention includes methods, devices, systems, circuits and associated computer executable code for detecting and predicting the position and trajectory of surgical tools. According to some embodiments of the present invention, images of a surgical tool within or in proximity to a patient may be captured by a radiographic imaging system. The images may be processed by associated processing circuitry to determine and predict position, orientation and trajectory of the tool based on 3D models of the tool, geometric calculations and mathematical models describing the movement and deformation of surgical tools within a patient body.

Abstract: A method of analyzing a medical image, the method comprising making a measurement on a 2D medical image of an organ and correcting the measurement in view of an angle of incidence between an imaging instrument and an imaged organ in the 2D medical image.
