Display an array as an image Tkinter - python-3.x

Question

I'm attempting to display an image from a compressed DICOM data array using tkinter. I compressed the image to an 8-bit numpy array. I know that the array can be visualized, as I have visualized it using both cv2 and matplotlib. Below is how I created the data:
import cv2
import numpy as np
import pydicom #https://pydicom.github.io/pydicom/stable/api_ref.html
import os
import glob
from PIL import Image, ImageTk
import PIL
import tkinter as tk
from pathlib import Path
path = Path("C:/Users/H61972/Desktop/1-1058/DICOM")
os.chdir( path )
os.getcwd()
print(__doc__)
#Get dicom files sorted by filename
def get_dicom():
return glob.glob("**/IM*",recursive=True)#slices
#return one file to be read at a time
def load_image(dicom):
ds = pydicom.read_file(dicom)
#print(ds.SliceLocation)
data = np.array(ds.pixel_array)
#data = data - np.min(data)
x = np.max(data)/255
data = data/x
data = np.clip(data, 0, 255)
return data
dicom = get_dicom()
def process_frame():
global data
frame = load_image(dicom[10])
frame = cv2.equalizeHist(frame)
frame = cv2.blur(frame,(5,5))
return frame
And below is the Tkinter gui I am building:
class mainWindow():
def __init__(self):
self.root = tk.Tk()
self.frame = tk.Frame(self.root, width=500, height=400)
self.frame.pack()
self.canvas = tk.Canvas(self.frame, width=500,height=400)
self.canvas.place(x=-2,y=-2)
data= process_frame()
self.im=Image.frombytes('L', (data.shape[1],data.shape[0]), data.astype('b').tostring())
self.photo = ImageTk.PhotoImage(image=self.im)
self.canvas.create_image(0,0,image=self.photo,anchor=tk.NW)
self.root.update()
self.root.mainloop()
mainWindow()
Any advice would be much appreciated!

I found a solution to most of my problem, however I have created a new problem in doing so. Now when I run the program I create an extra window. Here are my changes:
class DICOM(tk.Tk):
def __init__(self, *args, **kwargs):
tk.Tk.__init__(self, *args, **kwargs)#initialized tkinter
container = tk.Frame(self)#define our tkinter container
container.pack(side ="top", fill="both", expand=True)
container.grid_rowconfigure(0,weight=1)
container.grid_columnconfigure(0,weight=1)
self.frames = { }
#for F in (StartPage, Viewer):
frame = mainWindow(container, self)
self.frames[mainWindow] = frame
frame.grid(row =0, column =0, sticky ="nsew")
self.show_frame(mainWindow)
def show_frame(self, cont):
frame = self.frames[cont]
frame.tkraise()
class mainWindow(tk.Frame):
def __init__(self, parent, controller):
tk.Frame.__init__(self, parent)
self.controller = controller
self.root = tk.Toplevel(class_=self.controller)
# self.frame = tk.Frame(self.root)
# self.frame.pack()
self.canvas = tk.Canvas(self.root)
self.canvas.place(x=0,y=0)
data= process_frame()
self.im=Image.frombytes('L', (data.shape[1],data.shape[0]), data.astype('b').tostring())
self.photo = ImageTk.PhotoImage(image=self.im)
self.canvas.create_image(0,0,image=self.photo,anchor=tk.NW)
self.root.update()
#self.root.mainloop()
app = DICOM()
app.geometry("800x800")
app.title("Head CT Volumetric Analysis")
app.config(bg="gray")
app.mainloop()
How can I prevent this extra window from appearing?
