Dose estimation from one organ to another.

This MS EXCEL spreadsheet uses the S-factor formalism to estimate the dose from one organ to another arising from any one of 3 user selected radioisotopes in a specified quantity. This is the Medical Internal Radiation Dose as described in Cherry, Sorenson and Phelps book Physics in Nuclear Medicine.

An automated excel spreadsheet hand calculation for MammoSite.

This program was designed for MammoSite being treated with a Nucletron afterloader using a V-2 microselectron source. The strength page will need to be updated with daily decay tables for your own source. The program assumes that odd number treatments are done in the morning and even number treatments are done in the afternoon.

To independently check your TPS calculation with Isotope Products Laboratories (IPL) Cs-137 sources. Reference used and instructions for use are available upon request.

Warning: The absolute dose rate table for IPL source is different from 3M source.

HDR automatic secondary calculation program

This program automatically reads a text file with HDR dwell positions and calculates the dose to a user-specified point. It currently only reads Varian BrachyVision text files, but if I receive examples of other systems’ output I can incorporate them. It generates an Excel sheet with the dose comparison data for the user to print and sign. The total time for one handcalc is less than 30 seconds using this program.

To use HDR HandCalc with BrachyVision 10:
You have to edit the forms.dat file on the BrachyVision computer.
The path is found by looking in brachy under Help and about and system info. Look until you find the title that says: “Directories and Paths” then look under “report template directory” This is the path to forms.dat. Then you can edit forms.dat with notepad and remove the “#” from the last 4 lines that have the “#” in front of it.

You must download this 100 MB MATLAB standalone program, otherwise the program will not be able to run successfully.

Spreadsheet to calculate doserates near Cs137 tube sources based on away-and-along doserate lookup tables.

Spreadsheet to calculate doserates near Cs137 tube sources based on away-and-along doserate lookup tables. Enter values into yellow-colored cells (xyz (cm) coordinates of source tip and ends, mgRaeq for each source, and xyz coordinates of up to 6 dose points). If desired, enter computed doserates from your planning system for comparison to these values.

Pick an isotope and a date and this spreadsheet will do the rest..
Includes most popular isotopes in radiotherapy, with space to include your own. (137Cs, 60Co, 198Au, 125I, 131I, 192Ir, 103Pd, 32P, 153Sm, 90Sr, 90Y)

This excel spreadsheet is very basic but makes life easy (which lets face it, that’s what it’s all about).

It shows decays for 137Cs, 60Co, 198Au, 125I, 131I, 192Ir, 103Pd, 32P, 153Sm, 90Sr, 90Y

All you need to do is pick your isotope and enter the calibration date and activity. This sheet then calculates your activity today, at daily intervals from calibration, at any date of your choice and at 5&10 half lives (for disposal considerations).

There is plenty of space available to add any additional isotopes that you use frequently, although you’ll have to look up the half lives for these first.
