Access to the Particle Irradiation Data Ensemble
PIDE in a Nutshell
- PIDE is a radiobiological database compiling more than 1100 pairs of in-vitro cell survival experiments after photon and ion irradiation.
- It is a compilation of results drawn from 115 publications.
- It is convenient to study the relative biological effectiveness (RBE) for clonogenic cell survival as endpoint, or to benchmark RBE predicting models against experimental data.
- The most recent version PIDE 3.2 also provides the raw data (dose and surviving fraction) for most of the experiments.
- PIDE contains experiment specifications, i.e. the investigated cell lines, radiation qualities used and delivery techniques; all of these are relevant for RBE.
- This allows to investigate generic trends and impacting factors of the measured radiation effects.
- PIDE uses the linear quadratic model to parameterize the dose response.
- Data are presented as tables stored in easily accessible file formats: an Excel file (experiment description and linear-quadratic parameters) and ASC-II tables (raw data).
- PIDE is freely available to the research community after registration on this home page.
- It will be updated from time to time.
- The developers work on PIDE continuously by gathering new publications, so hints from the community about publications missing so far in PIDE are most welcome.
Detailed information on the update of the PIDE to version 3.2 with general results will be published soon. Information on the development of the PIDE 2.0 as well as first results are published in , which is the current reference publication for PIDE.
Release of PIDE Version 3.2
Bug fixing: For a few experiments the complete set of certain LQ parameters was added, which was missing before.
Release of new update: PIDE 3.1 (containing raw survival data)
T. Pfuhl joins the PIDE developer team, cross-checking all data for consistency within the database
Bugfixing and preparation of new release
A. Bothe works on the update to PIDE 3.0 (internal version) as part of his master thesis, including raw data of experiments
A paper on the set-up of PIDE2.0 and about first obtained scientific results is published in an open access Journal
A contribution of the PIDE project was published on the NASA website The Health Risks of Extratesetrial Environments (THREE)
