Abstract
A method for acquiring a sequence of fluoroscopic images of a subject acquires and displays a basis image from a fluoroscopic imaging system. A region of interest is defined within the displayed basis image in response to one or more viewer instructions entered on the displayed basis image. One or more signals are generated that adjust the position of one or more components of the fluoroscopic imaging system according to the one or more viewer instructions.
Claims6
A method for acquiring a sequence of fluoroscopic images of a subject, using a fluoroscopic imaging system comprising a display and a collimator which is not fully radiopaque, the method comprising:
- capturing a 2D basis image using the fluoroscopic imaging system;
- displaying the basis image on the display;
- defining a single region of interest within the displayed basis image responsive to a viewer instruction entered on the displayed basis image;
- adjusting the collimator according to the defined single region of interest;
- while maintaining the collimator adjustment for the entire acquisition sequence, acquiring the sequence of fluoroscopic images using the fluoroscopic imaging system;
- and
- automatically displaying, in an image area on the display, (i) the defined single region of interest of one of the acquired sequence of fluoroscopic images and (ii) the background portion of the basis image outside the defined single region of interest, wherein the displayed defined single region of interest is displayed at a higher contrast or higher resolution than the displayed background portion.
