    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.

    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 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： Method and apparatus for assessing tissue motion and deformation is provided. Sequential frames of data representative of tissue are accessed. A region of interest is defined on a current frame of data, and first locations of a set of features within the region of interest is identified. Each feature in the set of features identifies a location within the tissue. Second locations of the set of features are located on a consecutive frame of data. Velocity vectors are calculated based on the first and second locations of the set of features, and a continuous spatial and temporal velocity distribution is reconstructed by fitting the velocity vectors. The region of interest is modified on the consecutive frame based on the velocity distribution to follow motion and deformation of the tissue.
