Masking the image [message #90624]

Folks,
Hi,
I am analyzing some radar data and the outputs are epsilon and sigma. In the data plot, i have a M*N matrix that in some areas, i do not have data but during the analysis, some wrong out puts showed up. As you can see here (the gray areas): (http://s16.postimg.org/ks92qc2dx/2015_03_19_172804.png). As you can see from this image, in the areas that i do not have data i get some wrong value (like 24 which is constant in this areas). I want to mask out thus areas.

mask = image(where ( image eq 24 ))
image = image * mask

But this might be not good solution, because probably in the areas that i have data, i have correct 24 value, which i do not mask those data.
Will you please give me some hints, tricks to solve this?
Thanks for any kind of helps in advance,
Cheers,
Dave
