Radiographic methodology 1, 7.5 credits

Part 1: Radiation physics, 4.5 HE credits

• account for the basic radiation biophysics within diagnostic image and functional medicine from concept such as energy, mass, charge and interaction
• describe the physical and technical processes in the image for a X-ray image from X-ray tubes to screen
• describe in what way photons be attenuated in a material and how the activity of a radioactive substance decreases with the time
• explain how setting parameters that tube voltage and tube current influence the radiation quality at radiography
• account for the radiation concepts absorbed dose, effective dose and equivalent dose
• describe the properties and structure of digital images
• give examples of appropriate measures to minimise radiation doses to patients and staff and optimise the diagnostic quality of the image at the same time within X-ray and nuclear medicine.

Part 2: Radiographic techniques, 3 HE credits

• describe at a general level the structure and use for different radiographic modality such as the computer tomograph, the magnetic resonance imaging, the ultrasound equipment, analysis, mammography device and the gamma camera
• explain how information to patients, referrals and radiographic images are managed and archived in the computer systems RIS and PACS.

The course is divided in two parts:

Module1
This part is carried out with a number of lectures. The part also includes a compulsory laboratory session where the student measures scattered radiation in a radiography.

Module 2
This part is carried out with lectures and field studies on different modality. The students are divided into groups, and each group is assigned a modality. Each group independently produces a poster on their modality that is then presented orally in a poster exhibition at the end of the part.

Part 1 is examined through a written examination with the grading scale Fail/Pass/Pass with distinction. Furthermore, submitted and approved laboratory reports are required.

Part 2 has the grading scale Failed/Passed/Pass with distinction and be examined through active a written examination

A Pass with distinction in the course requires a Pass with distinction in part 1 and laboratory reports that have been submitted on time, and a Pass with distinction grade in part 2.

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.

Course evaluation will be carried out in accordance with the guidelines established by the Board of Education at Karolinska Institutet.
