Prescribing, Recording, and Reporting Electron Beam Therapy (Report 71)

ICRU Report 71, Prescribing, Recording, and Reporting Electron Beam Therapy. The Report extends the concepts and recommendations for photons contained in ICRU Reports 50 and 62 to electron beam therapy. Reflecting the similarities between electron and photon treatments, the section on volumes in the present Report is very similar to the section on volumes in Reports 50 and 62, but evolutionary clarifications applicable to both modalities are presented. The concepts of Gross Tumor Volume (GTV), Clinical Target Volume (CTV), Planning Target Volume (PTV), Organs at Risk (OARs) and Planning Organ at Risk Volume (PRV) are recalled, or refined, and new examples are given to illustrate these concepts.


Image Quality in Chest Radiography (Report 70)

Image quality in chest radiography is an important, but complex subject. The complicated anatomy of the chest, as well as the various ways that chest disease may manifest, require careful consideration of radiographic technique. The manner in which human observers deal with the complexity of chest images adds further dimensions to image analysis that are not found in other radiographic examinations. more

Direct Determination of the Body Content of Radionuclides (Report 69)

Previous ICRU reports have dealt with the formulation and properties of tissue substitutes and phantoms that are used to calibrate in vivo measurement systems. This report provides guidance on the overall process of the direct measurement of radionuclides in the human body for radiation protection and medical applications.


Retrospective Assessment of Exposure to Ionising Radiation (Report 68)

Basic dose quantities used in dose reconstruction are defined. The following dose -reconstruction methods based on measurements performed for individual persons are reviewed: electron paramagnetic resonance (EPR) measurements with tooth enamel, analyses of dicentric chromosomes and chromosome translocations, counting of micronuclei in lymphocytes, somatic mutation assays, and measurements of radionuclide activities in the human body.


Absorbed-Dose Specification in Nuclear Medicine (Report 67)

A number of reasons have led to a reappraisal of dose specification for nuclear medicine. These include an appreciation of non-uniformities in the distribution of radioactivity in the body, at all levels, for even the most common diagnostic and therapeutic agents; an increasing need to deal with the complexities of varying dose rates; the imperative to provide individual rather than standardised dose estimates as targeted radio-nuclide therapy becomes more sophisticated; as well as improvements in technology.


Determination of Operational Dose Equivalent Quantities for Neutrons (Report 66)

This Report provides guidance for the measurement of the operational dose equivalent quantities for neutron radiation, taking into account the recommendations of ICRP Publication 60.
