Abstract: Methods and systems are provided for generating regional digital subtraction angiography (DSA) images and roadmap images with landmarks. In one embodiment, a method comprises generating a mask from a set of mask images of an anatomy of a subject, and generating a masked image by applying the mask to acquired image data of the anatomy of the subject, including weighting the mask differently inside a region of interest (ROI) of the image than outside the ROI, the weighting inside ROI independent of the weighting outside the ROI. In this way, a user may be able to adjust a relative magnitude of subtraction inside and outside the ROI, and thus be able to visualize both vasculature and landmarks within the same image frame.

Abstract: The present approach relates to the fabrication of radiation detectors. In certain embodiments, additive manufacture techniques, such as 3D metallic printing techniques are employed to fabricate one or more parts of a detector. In an example of one such printing embodiment, amorphous silicon may be initially disposed onto a substrate and a laser may be employed to melt some or all of the amorphous silicon so as to form crystalline silicon circuitry of a light imager panel. Such printing techniques may also be employed to fabricate other aspects of a radiation detector, such as a scintillator layer.

Abstract: Systems and methods for generating an X-ray image using a digital flat panel detector with a squircle shape are described. The flat panel X-ray detector contains a circuit board, a light imager electrically connected to the circuit board, and a scintillator coupled on the light imager. The detector has superellipse shape or a cornerless shape with a first substantially straight edge and a second substantially straight edge running substantially perpendicular to the first edge, wherein the first and second edges do not physically intersect with each other at 90 degrees. The flat panel detector with this shape can be used in an x-ray imaging system that uses the detector to detect x-rays and produce an x-ray image. With this shape, the active sensing area of the detector can be similar to those currently available with rectangular or square flat panel detectors, while using less material to create the detector.

Abstract: This disclosure presents systems and methods that synchronize an x-ray imaging system with the heartbeat of a patient. A patient's heartbeat is sensed with a cardiac monitoring unit, and a processing unit generates x-ray pulses that are synchronized with the patient's heartbeat. Based on the real-time heartbeat information, an x-ray imaging device can be operated to obtain x-ray images at various states of the cardiac cycle. The x-ray images taken over several cardiac cycles can be combined based on the relative state of the cardiac cycle in which the images were obtained to achieve high temporal resolution of a cardiac cycle. Additionally, x-ray images obtained at common relative states of the cardiac cycle can be combined to provide higher quality cardiac image or images.
