App Store Description

In practice of radiotherapy, do you often want to check easily the BED and EQD?
We considered that it is wonderful to calculate them with iPhone, iPod and iPad that we carry always.
That’s why we designed new App “EQD calculator”.
Considering use in practice, primary concept of design is easy to use and quick to get the results.
In practice, we think that EQD is more useful than directly use of BED, so we named this App as “EQD Calculator”.
Please try EQD calculator!

We have released “TDF Calculator” that is capable to calculate the TDF factor defined by Orton et al.
Please, try also “TDF Calculator”.

#Strong points
- This App is designed for the professionals working in the field of Radiation Oncology.
- Although there are a lot of numbers on the screen, this App is designed to look like a table calculation, therefore you can understand easily the indication of each values.
- You can refer alpha/beta ratio and tolerance dose tables in this App.
- You can organize this App with URL scheme (jp.37.EQDcalculator://) in other App such as launchers.

#Main features
- This App calculates Biologically Effective Dose (BED) defined by Linear-Quadratic (LQ) model. Additionally, this App can calculate Equivalent Dose (EQD) in indicating fraction dose simultaneously.
- This App can also calculate the fraction dose which is equivalent in indicating fractionation times. Therefore, when you need to change the schedule of radiotherapy, you can keep the influences of change in the treatment to a minimum, estimating with this App.
- This App can calculate these values together in three different conditions stated by three parameters (fraction dose or total dose, number of fractions and alpha/beta ratio), and summation of them automatically.
- Setting either a total dose or a fraction dose, related fraction dose or total dose is calculated respectively, depending on the fractionation times.
- This App (from ver.1.2.0) is just designed for iPhone and iPad with iOS8.
