In this work, we propose a method to segment endoscope and guidewire from 2D X-ray fluoroscopic images of an endoscopic retrograde cholangiopancreatography (ERCP). We used an improved U-Net model. We obtained a Dice score of 0.94±0.05 for endoscope segmentation and a Hausdorff distance of 24.26 pixels for the guidewire segmentation. These preliminary results pave the way for further applications aiming at aiding the medical procedure.

Background: Accurate acetabular cup orientation in total hip arthroplasty (THA) is crucial for successful outcomes. Intraoperative fluoroscopy may be used to evaluate acetabular cup placement. This study aimed to evaluate the accuracy of purely visual estimation of cup inclination and anteversion using intraoperative fluoroscopy, considering different surgeon experience levels and cup designs.

Objectives: Establishing paediatric DRLs is challenging due to sparse data availability. The objective was to assess paediatric fluoroscopic dose levels in Dutch clinical practice, as current diagnostic reference levels (DRLs) need updating following the European Guidelines on DRLs for Paediatric Imaging (PiDRL).
Material And Methods: Air Kerma-area Product (KAP) values were retrospectively collected from paediatric patients (0-18 years) who underwent fluoroscopic procedures in nine Dutch hospitals between 01-01-2017 and 01-06-2021.

Background: Digital dynamic radiography (DDR), integrated into Konica Minolta's portable mKDR system, provides dynamic imaging for pulmonary, orthopedic, and interventional applications. While DDR is not classified as fluoroscopy, its use of pulsed x-rays for cine-like image sequences raises concerns about radiation exposure and shielding, particularly given the absence of a primary beam stop, high output capabilities, and increasing clinical adoption.
Purpose: To characterize the primary and scatter radiation output of a DDR system and compare it against commonly used mobile C-arm fluoroscopy units, and to evaluate shielding requirements and potential occupational exposure risks associated with DDR use.

Background: Low back pain is a prevalent issue with various etiologies, one of which includes pars interarticularis (pars) defects. While traditional fluoroscopic guidance has been the standard for administering injections, both fluoroscopic and ultrasound-guided injections for the management of low back pain have been shown to be similar in efficacy. The benefits of ultrasound guidance include real-time visualization, reduced radiation exposure, and improved patient access.

Hip arthroscopy has a steep learning curve with femoral osteoplasty being one of the most challenging technical aspects of the procedure. The authors discuss a methodical system of preoperative templating and intraoperative fluoroscopic evaluation to ensure adequacy of resection and correction of impingement. There have been multiple methods developed to help aid surgeons in intraoperative decision making during cam correction.
