Book excerpt: This publication reports the results of a recent IAEA coordinated research project on patient dose optimization in fluoroscopically guided interventional procedures. The optimization of radiological protection of patients undergoing medical exposure has become an important issue, since many surgical procedures have increasingly been replaced by interventional ones, which can cause higher radiation exposure. The summary presents detailed information on the assessment of high skin doses, analyses the factors causing radiation skin injury and makes recommendations on how to avoid or reduce the li.

This book was released on 2014-05-14 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Report is focused on the use of fluoroscopic systems as a tool for guiding diagnostic and therapeutic procedures because higher radiation doses (compared to conventional radiography and fluoroscopy) are received regularly from some types of FGI procedures and occasionally from many other types of FGI procedures. Other medical applications of fluoroscopy (e.g., examination of the gastrointestinal system, guiding open surgical procedures) are outside the scope of this Report. Computed- tomography-guided interventional (CTGI) procedures are not discussed in detail due to continuing changes in the technology driven by the evolution of multi-slice computed tomography (CT) detectors. However, the principles presented in this Report are generally applicable to these domains. Most of the recommendations contained in this Report should be applied in all settings where fluoroscopic guidance is used. Within the context of radiation dose management, the goal of this Report is to supply information that helps optimize patient outcomes without compromising worker safety. However, radiation is not the only risk to which patients and workers are exposed. In many cases, radiation is a minor component of overall risk. In these situations, too great a focus on radiation safety (e.g., the use of unnecessarily thick lead aprons) may reduce the overall safety of patients or workers. Some beneficial, clinically-justified FGI procedures, even when optimized for radiation protection, deliver substantial doses of radiation to patients. This puts the patient at risk for radiogenic stochastic effects and occasionally induces radiogenic deterministic effects. However, a complete risk analysis usually identifies many other procedural hazards and will often conclude that radiation is one of the lesser hazards from FGI procedures. While the decision to conduct an FGI procedure assumes that the use of ionizing radiation is warranted by the disease state for which
Download or read book Radiation Dose Management of Pregnant Patients Pregnant Staff and Paediatric Patients written by John Damilakis and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whenever a diagnostic or interventional X-ray examination of a pregnant patient is considered to be necessary, conceptus dose estimation is an essential step in assessing the radiogenic risks to the unborn child. Accurate estimation of embryo/fetus radiation dose is also needed after accidental exposure of a pregnant patient from an X-ray procedure. The exposure of pregnant patients to medical X-rays is often a complex case and involves emotionally sensitive issues for both prospective parents and physicians. Conceptus dose assessment is not always easy. Medical physicists should be able to assess conceptus doses and risks from diagnostic and interventional procedures and also to place the risk in a perspective from which an informed decision can be made. Pregnant medical professionals working with radiation have many misconceptions about the risks of ionizing radiation on the unborn child. Medical radiation workers of childbearing age should be aware that careful planning and dose optimization of examinations can address their concerns and permit, in the vast majority of cases, safe performance of procedures. Pediatric patients requiring diagnostic and interventional procedures are exposed to diagnostic and interventional X-rays. Pediatric patients are more sensitive to radiation than adults and, for this reason, accurate assessment of doses and risks is needed in these cases. Medical physicists should be able to assess paediatric doses and risks from diagnostic and interventional procedures. Several techniques and tools have been developed for dose optimization of radiographic, fluoroscopic, computed tomography and fluoroscopically-guided interventional pediatric procedures. The scan parameters should be adjusted for patient size and body region. Part of Series in Physics and Engineering in Medicine and Biology.

Download or read book Radiation Dose Optimization for Critical Organs written by Yasaman Khodadadegan and published by . This book was released on 2013 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ionizing radiation used in the patient diagnosis or therapy has negative effects on the patient body in short term and long term depending on the amount of exposure. More than 700,000 examinations are everyday performed on Interventional Radiology modalities [1], however; there is no patient-centric information available to the patient or the Quality Assurance for the amount of organ dose received. In this study, we are exploring the methodologies to systematically reduce the absorbed radiation dose in the Fluoroscopically Guided Interventional Radiology procedures. In the first part of this study, we developed a mathematical model which determines a set of geometry settings for the equipment and a level for the energy during a patient exam. The goal is to minimize the amount of absorbed dose in the critical organs while maintaining image quality required for the diagnosis. The model is a large-scale mixed integer program. We performed polyhedral analysis and derived several sets of strong inequalities to improve the computational speed and quality of the solution. Results present the amount of absorbed dose in the critical organ can be reduced up to 99% for a specific set of angles. In the second part, we apply an approximate gradient method to simultaneously optimize angle and table location while minimizing dose in the critical organs with respect to the image quality. In each iteration, we solve a sub-problem as a MIP to determine the radiation field size and corresponding X-ray tube energy. In the computational experiments, results show further reduction (up to 80%) of the absorbed dose in compare with previous method. Last, there are uncertainties in the medical procedures resulting imprecision of the absorbed dose. We propose a robust formulation to hedge from the worst case absorbed dose while ensuring feasibility. In this part, we investigate a robust approach for the organ motions within a radiology procedure. We minimize the absorbed dose for the critical organs across all input data scenarios which are corresponding to the positioning and size of the organs. The computational results indicate up to 26% increase in the absorbed dose calculated for the robust approach which ensures the feasibility across scenarios.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Interventional fluoroscopy uses ionizing radiation to guide small instruments through blood vessels or other body pathways to sites of clinical interest. The technique represents a tremendous advantage over invasive surgical procedures, as it requires only a small incision, thus reducing the risk of infection and providing for shorter recovery times. The growing use and increasing complexity of interventional procedures, however, has resulted in public health concerns regarding radiation exposures, particularly with respect to localized skin dose. Tracking and documenting patient-specific skin and internal organ dose has been specifically identified for interventional fluoroscopy where extended irradiation times, multiple projections, and repeat procedures can lead to some of the largest doses encountered in radiology. Furthermore, in-procedure knowledge of localized skin doses can be of significant clinical importance to managing patient risk and in training radiology residents.
