Abstract: A system for selecting a zoom size of an anatomical image for display includes an image detector having a pre-defined field of view defining a maximum and minimum analog zoom fields of view corresponding to maximum and minimum analog zoom settings for at least one anatomical image; an image display displaying the anatomical image within the pre-defined field of view; a processing unit providing a selection of at least one anatomical image; and a network configured to interface the detector with the processing unit and the image display with the processing unit. The system enables establishment of at least one intervening selectable zoom setting corresponding to an intervening selectable zoom field of view between the maximum and minimum analog zoom fields of view, thereby establishing a first user profile. A second user profile overriding the first user profile can be established. A corresponding method is also disclosed.

Abstract: A C-arm X-ray system includes synchronized ECG gating for enhanced cardiac soft-tissue imaging. The system includes an X-ray source disposed on a C-arm for rotation in a circular path about a patient and configured to release X-ray radiation synchronously with an ECG-gating signal, an X-ray image sensor disposed on the C-arm in a fixed opposing position to the X-ray source and configured to rotate with the source and receive the X-ray radiation and an ECG unit for acquiring ECG data from the patient. The system also includes a digital image acquisition processor arranged in communication with the X-ray source, X-ray image sensor and ECG unit for acquiring 2D projection images at predetermined C-arm angulations in the presence of the ECG-gating signal and an image processor arranged in communication with the digital image acquisition processor to receive and process the series of 2D projection images and reconstruct a continuous 3D volumetric image of the patient's cardiac soft tissue therefrom.

Abstract: A method and system reduce radiation exposure by panning and zooming a first image of a patient acquired by an x-ray imaging system rather than using continuous radiation fluoroscopy. A first image of a region of interest is initially acquired. Subsequently, the patient may be repositioned with respect to the imaging system or a component of the imaging system may be repositioned with respect to the patient. The first image may be automatically panned on a display in response to the repositioning. A collimator may be adjusted to select a coverage area of the collimator.

The first image may be automatically panned on a display in response to the repositioning. A collimator may be adjusted to select a coverage area of the collimator. The first image may be automatically resized on the display based upon the size of the selected coverage area. An optimal imaging device parameter also may be selected based upon the selected coverage area. A second image may be acquired using the imaging system and automatically resized to substantially fill the display.
