(1.) Calculation of thyroid volumen on the basis of the lobes diameters

(2.) Calculation of (radio)nuclide uptake (f.e. uptake of radioiodine in the thyroid)

(2a.) Calculation of uptake of I-131 in the thyroid (This program can be saved as a file and launched in another PC, a browser with HTML and

(3.) Calculation of radioiodine dose (simplified)

(4.) Kinetic modeling I. (effective half-time, maximal uptake and others, based on a series of measures) - for radionuclide therapy

(5.) Kinetic modeling II. (effective half-time, maximal uptake and others, based on three measures) - for radionuclide therapy

(6.) Calculation of dose of radioiodine or another radionuclide for treatment (modified Marinelli-formula)

(7.) Dosimetry of α- and β-radiation

(8.) Dose rate and absorbed dose of γ radiation (in a distance from a point source)

The algorithm calculates the uptake of a given radionuclide in an organ. It gives also the time elapsed between calibration/application of the radiopharmaceutical and measure, as well as decay factor. Application (i.e., swallowing of iodine capsule or injection od radiopharmaceutical) should take place immediately after the calibration (measure of the radiopharmaceutical, f.e. iodine capsule).

In order to perform the calculations, one should first choose the nuclide and/or its physical half-time (default for some nuclides), and then write the dates and hours of calibration/application of the radiopharmaceutical and the measure of the patient (year: four-digit format, month, day, hour and minute: two-digit format; default: year and month - current) and the results of measures of the background and the nuclide (or the patient, respectively). In order to repeat the calculations with use of (partially) different data (i.e. the same parameters for another patient or the same patient but another time), you can modify only these data, which have changed, (without the necessity to enter all the remaining ones). Not-entered data will be ignored in the calculations (f.e., it is not necessary to enter the dates). In order to get further information, hover the mouse cursor over the appropriate form field.
