On the justification of justification in radiation ... optimisation of protection, dose limitation and justification. Radiographers are important stakeholders in the maintenance of the system, both legally, ethically and practically. The practice of justification of medical exposure was found to be very poor. Optimisation. Radiation protection is based on the application of 3 principles, i.e., justification, optimisation and limitation, which have been established by the International Commission of Radiation Protection (ICRP) in the recommendation n°26 of 1977. Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Introduction - Principles of Radiation Protection. 2. with justification, optimisation and referral criteria ... for users of CBCT. Written procedures for all medical exposures, Justification, Optimisation, clinical audit, For every dental x-ray, the dose to the patient from the exposure should be kept as low as reasonably practicable for the intended diagnostic purpose. Therefore, 8.06% (105 out of 1302 pediatric patients) were protected from unnecessary or additional radiation exposure.The . .e 13 .6 eV) is the least energy required to eject the K-shell elec- There is no justification for the routine radiography of new patients prior to clinical examination. Recommended citation ICRP, 2006. Justification and optimisation In medicine, the use of radiation must be justified. This Code of Practice for Diagnostic and Interventional Radiology is issued by the Director for Radiation Safety under section 86 of the Radiation Safety Act 2016. Additionally, diagnostic procedures use diagnostic reference levels, which are not seen as limits but instead indicate if a dose received from an imaging procedure is unusually high or low, to guide the optimisation process and thus help manage patient exposures (ICRP . Radiography clinical education - improving the efficacy of education in the clinical setting - exploring challenges along with radiographer motivation and clinical teaching skills. Introduction.

If a patient is exposed to X-rays for the purpose of producing a radiograph, but the resulting image is not of adequate quality for clinical use, then the patient has been put at risk for no benefit. Dose Optimization in Interventional Radiology Aida M. Lobriguito, MSc, CSci, MIPEM Medical Physicist King Fahad Medical City National Training Course on Justification and Optimization of Protection in Diagnostic X-ray Imaging and Interventional Radiology (18-20 October 2016) Below an energy limit of 13 .6 eV, radiation is not able to induce ion-isation; therefore, radiation with an energy higher than 13 .6 eV is called ionising while radiation with an energy lower than 13 .6 eV is called non-ionising. Rare earth systems with speed indices of about 400 are recommended for general radiography (Table 5) and 600 may be appropriate for certain lumbar spine projections [22, 23]. Only 11 clinicians knew the terminology of Justification and Optimization and limitations to radiation protection. principles of justification, optimization and limitation, including the consideration of the Levels of Diagnostic Reference NRD [ 2 ] (Gholami and Al, 2015).The three great principles of protection against radiation enacted by directive 96/29 Euratom are the justification of the of justification and optimisation, in a context where dose limits are not applied to The 'Justification and Optimization" principles are part of the European directives included in the regulations of the Union member countries.These two radiological protection principles play an important role especially in the medical field responsible today for 98% of exposures to non-natural sources of .

On the assessment of knowledge of justification of medical exposure, the majority of the respondents have adequate knowledge with 84.4% medical practitioners and 64.6% dental practitioners. The basic concepts of dose optimisation for diagnostic and therapeutic procedures involving the use of radionuclides are explained, and an individual chapter focuses specifically on dose optimisation in the paediatric population. Radiation protection is based on the three fundamental principles of justification of exposure, keeping doses (of ionising radiation ) as low as reasonably achievable (optimisation) and the application of dose limits. Justification and Optimisation of radiation dose and image quality in CT; Contrast media protocol optimization in CT ; Low dose imaging in CT Unit title: Dental Radiography: Operator ♦ Legislation Ionising Radiation (Medical Exposure) Regulations 2017 (IRR(ME)2017); duties of the employer, the referrer, the practitioner and the operator. Because medical exposure of radiation has unique considerations, diagnostic reference level is generally used as a reference value, instead of dose limits. General principles of radiation protection from the hazard of ionizing radiation are summarized as three key words; justification, optimization, and dose limit. This course will bring you up to date with the legislation concerning dental radiography and ensure you are aware of statutory responsibilities. 9000 Gent. Optimisation relies on professional competence and skill. Jakob Van Acker. The basic aim of optimisation of radiological protection is to adjust imaging parameters and institute protective measures such that the required image is obtained with the lowest possible dose of radiation, and that net benefit is maximised to maintain sufficient quality for diagnostic interpretation. Special consideration should be given to . In these cases, justification and optimisation are strongly emphasised. For medical exposures of patients as part of their own investigation or treatment, dose limits Member Feedback on Radiography and Radiation Protection In radiography what is meant by the term "justification"? The dose limits, which have changed several times, apply to radiation workers and members of the public. The majority (80%) performed radiography in towns of 3000 people or less. During.
