Modern Fluoroscopy Imaging Systems
نویسنده
چکیده
Fluoroscopy, or real-time projection X-ray imaging, has been in clinical use since shortly after Roentgen’s discovery of X-rays. Early fluoroscopes consisted simply of an X-ray source and a fluorescent screen, between which the patient was placed. After passing through the patient, the remnant beam impinged upon the fluorescent screen and produced a visible glow, which was directly observed by the practitioner.

Hysterosalpingography using a flat panel unit: Evaluation and optimization of ovarian radiation dose.
PURPOSE The aim of the present study was the evaluation and optimization of radiation dose to the ovaries (D) in hysterosalpingography (HSG). METHODS The study included a phantom study and a clinical one. In the phantom study, we evaluated imaging results for different geometrical setups and irradiation conditions. In the clinical study, 34 women were assigned into three different fluoroscopy...
متن کاملThree-dimensional image integration: a first experience with guidance of atrial fibrillation ablations.
The treatment of atrial fibrillation (AF) can be challenging, with a rate control strategy not being optimal for all patients and antiarrhythmic drugs frequently ineffective and possessing serious adverse effects. A fluoroscopic or electroanatomic catheter-based approach is rapidly becoming one of the preferred treatments of AF.1-3 However, success rates are still not ideal and complications du...
متن کاملNew automated fluoroscopic systems for pediatric applications
Pediatric patients are at higher risk to the adverse effects from exposure to ionizing radiation than adults. The smaller sizes of the anatomy and the reduced X-ray attenuation of the tissues provide special challenges. The goal of this effort is to investigate strategies for pediatric fluoroscopy in order to minimize the radiation exposure to these individuals, while maintaining effective diag...
متن کاملSurgeon, staff, and patient radiation exposure in minimally invasive transforaminal lumbar interbody fusion: impact of 3D fluoroscopy-based navigation partially replacing conventional fluoroscopy: study protocol for a randomized controlled trial
BACKGROUND Some symptomatic degenerative conditions of the lumbar spine may be treated with spinal fusion if conservative treatment has failed. The minimally invasive technique of transforaminal lumbar interbody fusion (MIS TLIF) is increasingly used but has been found to generate increased radiation exposure to the patient and staff. Modern three-dimensional (3D) C-arm devices are capable of p...
متن کاملNavigation for fluoroscopy-guided cryo-balloon ablation procedures of atrial fibrillation
Atrial fibrillation (AF), the most common arrhythmia, has been identified as a major cause of stroke. The current standard in interventional treatment of AF is the pulmonary vein isolation (PVI). PVI is guided by fluoroscopy or non-fluoroscopic electro-anatomic mapping systems (EAMS). Either classic point-to-point radio-frequency (RF) catheter ablation or so-called single-shot-devices like cryo...
