How To Create a Coldfusion Struct Using a Query

I would like to create a structure with the data from a query in coldfusion 9.
The data ultimatley needs to be put into a chart for display.
I can not get all of the needed data in my initial query because some of the fields are encrypted and so I have to decrypt them on the page to retrieve the actual values.
I want to create a structure to hold the initial data and the decrypted data and use that as a basis to fill a cfchart.
I'm having a little trouble with the syntax. I've previously have done this type of thing with an array but I'd like to use a structure.
Can you offer some advice on how to correctly create a struct from a cfquery?

This is what I have:

<cfquery name="somequery" >
    select field1, encryptedField2 from mytable
</cfquery>

<table>
<tr>
     <td>lable1</td>
     <td>lable2</td>
</tr>

<cfset MyStruct = StructNew()>
<cfset MyStruct.thing1 = "x">
<cfset Mystruct.thing2 = "y">

<cfoutput query="somequery">
    <cfset decryptedVal = #functionToDecrypt#>
    <tr>
         <td>#field1#</td>
        <td>#decryptedField2</td>
   </tr>

   <cfscript>
      StructInsert(MyStruct, "field1", field1)>
      StructInsert(Mystruct, "decryptedField2, DecryptedThing)>
   </cfscript>
</cfoutput>

</table>
