We propose a Position-guided Prompt learning method for Anomaly Detection in chest X-rays (PPAD). PPAD leverages learnable text prompt and image prompt to minimize the gap between pre-training data and task-specific data. Through the position-guided prompts, the model can focus on various region...
the system 100 to perform an operation including generating a spectral image based on spectral image data and identifying the position of a first reference marker 180i including a first material in a spectral image based on a first X-ray absorption K edge energy value 190I of the first ...
An X-ray technician will position you on an exam table and give instructions on how you should position your body for the X-ray. You can ask questions if you have them. What happens after the X-ray procedure? There are no side effects or after-effects of a regular X-ray and you sho...
7.11.6.4.2 x-Ray tube under the patient couch and position of the interventionalist Since the primary beam is much more intense at the patient entrance than at the exit, there is more scattered radiation surrounding the patient on the beam entrance side. For this reason, under-table x-ray...
limited FWHM of 1.7 μm, since in addition to spherical abberations of the lens, the through-hole on the last mirror introduced aberrations to the wavefront and a fine adjustment of the laser focus position was used to match the laser and X-ray focus after focal alignment of the ...

At the Advanced Photon Source (APS), each insertion-device (ID) beamline front end has two X-ray beam position monitors (XBPMs) to monitor the X-ray beam position for both vertical and horizontal directions. Performance challenges for a conventional photoemission-type XBPM during operations are ...
X-ray absorption spectroscopy (XAS) has become an indispensable tool to in situ investigate dynamic natures of electrocatalysts but still suffers from limited energy resolution, leading to significant electronic transitions poorly resolved. Herein, we highlight advanced X-ray spectroscopies beyond ...
Higher X-Ray Flux Source Numerous Advantages With its innovative high-power (25 W) X-Ray source technology, the ZEISS Xradia 600 Series Versa substantially increases X-Ray flux over its predecessors. The potential source pushes the envelope of efficacy with enhanced flux and throughput, resolution...
enabling medical professionals to precisely determine the location of the biopsy target. CT biopsy grid is suitable for percutaneous puncture positioning under the guidance of CT or X-ray, used for in vitro positioning, guiding the positioning of lesions in the patient's body and markin...
