QDOSE® Multi-purpose Voxel Dosimetry is indicated for use to provide estimates of radiation absorbed dose to organs and tissues of the body from medically administered radiopharmaceuticals, and to calculate total-body effective dose. Radiation absorbed dose calculations are based on clinical measurements of radioactivity biodistributions and biokinetics. QDOSE® is intended for applications in clinical nuclear medicine, molecular radiotherapy, radiation safety evaluations, risk assessment, record-keeping, and regulatory compliance. QDOSE® is indicated for use by professionals (medical physicists, radiologists and oncologists including nuclear medicine physicians), radiologic imaging technologists, health physicists and radiation safety officers and administrators, students in training, and others having interest in ability to calculate internal radiation doses from medically administered radiopharmaceuticals.

QDOSE® is a software package for calculating internal radiation doses from clinically administered radiopharmaceuticals. Patient time-activity data may be imported to QDOSE® in DICOM files from nuclear medicine clinical imaging. Dosimetry performed within QDOSE® is based on the use of calculated S values, determined for patient-like phantoms using a Monte Carlo method. The S values provide the average absorbed dose to a target organ generated by a unit of activity in a source organ time-activity curves from quantitative nuclear medicine imaging data are integrated to yield an estimate of the number of radionuclide decays representing the area under a time-activity function, similarly to the mathematical process used by OLINDA/EXM. QDOSE® dose calculations are performed by multiplying a source organ timeactivity curve integral by the S value generated from Monte Carlo calculations. The product of the dose calculations is an output of radiation absorbed doses to specified target organs per unit administered activity.

3D-RD-S is intended to estimate radiation absorbed dose (and related quantities) to tissues after administration of a radioactive product. For use with internally administrated radioactive products, 3D-RD-S should not be used to deviate from product dosing and administrations. Refer to the product's prescribing information for instructions.

3D-RD-S is a cloud-based software as a medical device (SaMD) that interacts with the user via web browsers (for example Google Chrome). Users are trained healthcare professionals with significant dosimetry knowledge and experience and also responsible for the input of the appropriate values and to make correct interpretation of the output data. 3D-RD-S takes numerical input data in the form of activity in source tissues as a function of time (TAC data) or the integral of the activity (TIA data) in source tissues over time. It then calculates the absorbed dose to a set of target tissues based on the organ sizes and anatomies of a set of standard phantoms. The software provides the user the ability to account for the differences in tissue masses between the phantoms and the subject and model uncertainties in the input data. Calculation results can be viewed and updated by other users. The software provides the ability to calculate absorbed doses and related radiobiological quantities from input data. The calculations can be made for supported radionuclides based on data in the report 89 from the International Council on Radiation Protection (ICRP). Doses to target tissues are a function of the activity integrated over time (time-integrated activity. TIA) in a set of specified source organs. The software provides two modules for the integration of input time vs. activity curve (TAC) data. First, the user can use curve fitting methods to estimate a curve that passes through the TAC data from a set of supported fitting functions. Visual and numerical indicators of how well the fitting function works with the data are provided. Notifications are given if fitting parameters are non-physical. The TAC data can then be integrated using the fitting function, or by approximating the activity between measured time points with line and assuming activity after the last time-point decays with the radionuclide's physical half-life. If desired, the user can use a combination of the curve fit, linear interpolation between the lines, and exponentially decaying extrapolation based on the physical half-life, to integrate the time-activity curves. The calculated radiobiological quantities purport to relate physical dose to biological response and are dependent on the specification of radiobiological constants. The guantities supported include the whole-body effective dose and the relative biological effectiveness (RBE) weighted dose. The effective dose is calculated based on ICRP tissue weighting factors. The RBE weighted dose is calculated using user specified RBEs for the different radiation types (standard values are provided as defaults). 3D-RD-S provides total and individual dose estimates for the various particle types, i.e., alpha particles, beta (+ and -) particles, discrete electrons (e.g., Auger electrons), and photons (gamma and x-rays). The resulting doses are plotted in a bar graph and can, along with input data, be exported in a spreadsheet.

The intended use of OLINDA/EXM is to provide estimates (deterministic) of absorbed radiation dose at the whole organ level as a result of administering any radionuclide and to calculate effective whole-body dose. This is dependent on input data regarding bio distribution being supplied to the application.

The OLINDA/EXM® v2.0 is a modification of OLINDA/EXM® v1.1 (K033960) and includes new human models and nuclides. OLINDA/EXM® 2.0 employs a new set of decay data recommended by the International Commission on Radiological Protection (ICRP). OLINDA/EXM® 2.0 introduces a new series of anthropomorphic human body models (phantoms), so new values of Specific Absorbed Fractions (SAF), di (T←S) were generated. These phantoms were based on updated values of the mass of the target region (mr) recommended by the ICRP. The base product design of OLINDA/EXM® V2.0 is the same as for the OLINDA/EXM® V1.1 (K033960).
