Optimal room layouts

[Rybeast]

I've started to progress throughout the game and I'm noticing that a lot of my rooms are becoming very sought after, particularly for the scanner and x-ray. Are there any pictures anywhere of what an optimal layout for each room looks like? Psychiatry is difficult for me, as I never know where to place the sofa and then the screen, especially when you can have emergencies of King Complex every now and then!

Any pictures or drawings of optimal layouts would be greatly appreciated!

The optimal layout would be where the sofa is closest to the door, so patients get in and out as fast as possible.
And the bookshelf should be close to the doctor's chair, so he doesn't waste so much time walking.

But I would build several rooms of certain kinds.
I often have 2+ GP's, pharmacies and psychs.

Is there hard data on this? Did someone make the effort and time some of these things? As silly as it may sound, I think that'd be great.
