I'm not too familiar with SciPy, but is this Image class the PIL Image
class?  Because if that's the case, PIL images can be trivially integrated
with Tkinter by using PIL's ImageTk module:

 from Tkinter import Label
 import ImageTk

 mylabel = Label()
 mylabel.pack()

 while True:
     image = process_and_return_image_data_with_scipy()
     label['image'] = ImageTk.PhotoImage(image)

I'm not sure how fast this is though (whether ImageTk.PhotoImage() creates 
a copy of the original image, etc.).
