[Responsibility and development in medical imaging]

The recent evolution in medical law, permitting a responsibility without objective fault, underlines obligations in radiology. The radiologist is a doctor, specialist, doing an act of radiodiagnosis of which he is responsible, so much in his decision that in his realisation. This concept is important because of the diversity of technical meanings, and the surgical consequences, realised by the radiologist. The medical fault must be examined by the radiologist, by degrees, according to the different responsibilities. Then, we describe a logical realisation of the radiodiagnosis act. At last, we explored the condition of the complain and jurisdictional followings.
