Radiographic methodology 3, 7.5 credits

To be qualified to a higher semester, it is required that the student has taken at least 15 ECT credits from last semester, and all credits from previous semesters.

On completion of the course, the student should be able to: • account for which measures and which equipment that should be used because the patient and personnel radiation protection should function satisfactory and in accordance with the regulations of the swedish radiation safety authority and the ALARA-principle on a department of radiology and a nuclear medical section • Reason about considerations that may arise such as the examination of women of fertile age, child examinations, supplementary images etc • account for various types of personal dosimeters and describe the basic principles of gas-filled detectors, scintillation detectors and semiconductor detectors • describe the interaction of radiation with tissue/DNA and discuss the factors that govern the grade of injury. • explain the concepts of absorbed dose, efficient dose and equivalent dose from radiation types different effects on biological tissue and the radiation sensitivity of different cells • use the most common tools within digital image processing

The course gives advanced knowledge of the biological injuries and risks that can arise in using ionising radiation. Knowledge is also provided about different ways of detecting radiation and the radiation doses that may occur in using medical equipment for ionising radiation. In order to understand adequate radiation protection measures in their professional function, advanced knowledge about the laws and regulations that control the subject area is provided both to patients and staff . The part also provides knowledge about radiation and its use in society and environment, and risks associated with this. A focusing is also made on image processing and which methods that are to raise the diagnostic value of a X-ray image. It´s made through practical exercises.

The course is mainly based on lectures and seminars. Practical exercises/laboratory sessions are made within digital image processing. These are compulsory.

For a Pass grade in the course so that is required passed participation in compulsory parts such as laboratory sessions and passed independent written examination. In consultation with the examiner of the course, the student may get a complementary assignment in case of absence from a compulsory part. The student is entitled to a total of six test occasions to get passed. In Connections to the course three occasions will be given One within the course, two occasions at future re-examinations. In some cases, it is required that the student submits an exemption application before he/she has the results of his/her latest completed examination. Three more opportunities are provided according to the same set-up when the course is given next time.

The student may be examined under a previous syllabus within a year after the date when a close-down or major changes of the course was decided.
