Abstract:
The present work refers to the dosimetry of the radiodiagnosis facilities, mainly focused on Computer Assisted Tomography and it has been structured in three parts, namely: I.Basics of image acquisition using computed tomography technique; II.Effective Dose calculation for a patient and its assessment using BERT concept; II.Recommended actions of getting a good compromise in between related dose and the image quality.
The aim of the first part is that the reader to become acquainted with the CT technique in order to be able of understanding the Effective Dose calculation given example and its conversion into time units using the BERT concept .
The drown conclusion is that:
- Effective dose calculation accomplished by the medical physicist (using a special soft for the CT scanner and the exam type) and, converted in time units through BERT concept, could be then communicated by the radiologist together with the diagnostic notes.
Thus, it is obviously necessary a minimum informal of the patients as regards the nature and type of radiation, for instance, by the help of some leaflets.
In the third part are discussed the factors which lead to get a good image quality taking into account the ALARA principle of Radiation Protection which states the fact that the dose should be ‘as low as reasonable achievable’.
