Pick a square from the left of the scanner and move it to the scanner bar to reveal the organ it contains. Once you determine what the organ is, move it over the square containing its name on the right side of the scanner bar. Once you have the organ over its name, just drop it. If you choose a wrong square, points will be deducted from your score and you will still have to find its proper location. Have all organs to their descriptions to complete the level.
