A customizable Excel spreadsheet for calculation of the monitor units necessary for an orthovoltage treatment field. Complete with energy, applicator, and cutout options.

The Orthovoltage Treatment Calculator was created in Microsoft Excel and is dependent on data stored in tabular format to the right of the print area. This facilitates the possibility of customization for users with different treatment units and data. The dropdown menus in the print area lookup the options and data stored in these tables.

The user first selects the potential energy that the orthovoltage unit is to operate at, and then selects the applicator that is to be used. The list of available applicator options is dependent on the selected potential energy. In the event that the source to surface distance is greater than or less than the length of the applicator, a positive or negative value may be entered into the “STAND OFF” field to produce an inverse square law correction that will be applied to the corrected dose rate.

Backscatter factors are tabulated from BJR 25 for each applicator and are accessed by the spreadsheet if no cutout is to be used during treatment. The worksheet will calculate the backscatter factor of an optional cutout based on its selected shape and associated dimensions. The calculated area is automatically converted to an effective diameter. The effective diameter is used to yield an accurate backscatter factor using interpolated TG-61 data from Ma et al. [Med. Phys. 28, No. 6, June 2001.]. For cutouts that are too irregular to be classified as a standard shape, the user can manually input the area.

After entering the total treatment dose and the number of fractions per treatment, the worksheet will return the calculated values for the corrected dose rate and the monitor units per fraction. The worksheet also provides the appropriate spaces for the input of the patient name, patient ID number, treatment site, and field number. For verification purposes, the current time is automatically stamped at the top of the print area and there is room for handwritten signatures of the pertinent staff at the bottom. A completed calculation sheet consists only of printer-friendly grayscale colors (see screenshot 2).
