Abstract: A method includes receiving an input signal indicative of a set of coordinates for tissue of interest in first imaging data. The set of coordinates corresponds to user identified measurement points on a perimeter of the tissue of interest in the first imaging data. The method further includes determining a measurement for the set of measurement points. The method further includes generating a set of fiducial markers for the first imaging data corresponding to the coordinates. The method further includes registering the first imaging data with second imaging data based on the fiducial markers. The method further includes visually displaying the second imaging data with the registered first imaging data superimposed there over.

Abstract: A method includes obtaining real-time imaging data of at least a sub-portion of an object and a region of interest therein. The method further includes displaying the real-time imaging data as the real-time imaging is obtained. The method further includes tracking extraction of a sample from the region of interest by an extraction device based on the real-time imaging data. The method further includes identifying an extraction location for the extracted sample based on the tracking and the real-time imaging data and generating a signal indicative thereof.

Abstract: A patient (12) is irradiated with x-rays (10) from an x-ray tube (A). X-rays that have passed through a region of interest of the patient are converted to a light image by a phosphor screen (14) on the dome shaped input face (16) of an image intensifier (B). The dome shaped input face causes the output optical image (20) of the image intensifier to be distorted with pin cushion distortion. The sweep pattern of the electron beam of a video pick up tube (24) of a video camera (C) is controlled by deflection plates (26a, 26b, 26c, 26d). A sweep control circuit (D) alters the sweep pattern such that electronic image representations generated by the video camera are distorted in a manner that is complementary to and cancels the image intensifier tube distortion. In this manner, the two distortions cancel and a man-readable image (28) displayed on a video monitor (22) is substantially distortion-free.
