ICRU Report 19. Radiation Quantities and Units

Radiation Quantities and Units

The unique radiation exposure conditions that exist in computed tomography (CT), during which thin slices of the patient are irradiated by a narrow, fan-shaped beam of x rays emitted from the x-ray tube during its rotation around the patient, have required the use of special dosimetry techniques to characterize the radiation doses to patients and to monitor CT system performance. This section d...

Safety of adjuvant intensity-modulated postoperative radiation therapy in endometrial cancer: Clinical data and dosimetric parameters according to the International Commission on Radiation Units (ICRU) 83 report.

AIM To report a single-institution experience using postoperative pelvic Intensity Modulation Radiation Therapy (IMRT) using tomotherapy accelerators (TA) in postoperative endometrial cancer (EC) regarding ICRU 83 recommendations. BACKGROUND IMRT in gynecological malignancies provides excellent dosimetric data, lower rates of adverse events and clinical data similar to historical series. MA...

Quantities and units in clinical chemistry.

HE COMMISSION ON CLINICAL CHESIIsTEY (CCC) of 1UPACt in 1965 nominated a Subeommission for Standards and Units ill Clinical Chemistry4 Concerning units, the primary task of the subcommission was to study (1) the individual and iiational efforts to counteract the increasingly chaotic use of quantities and units in clinical chemistry; (2) the current usage in related fields of science, especially...
