使用 PIL(PILLOW) Python 庫顯示 Dicom 圖像

Question

我正在嘗試使用以下代碼讀取和顯示 DICOM(.dcm) 圖像：-

import pydicom as dicom
import numpy as np
from PIL import Image, ImageEnhance, ImageOps
from PIL.ImageQt import ImageQt

def display_dicom_images(self, folder_Path):
    try:
        # Image parameters
        image_width = 382
        image_height = 382

        image_depth = 3
        self.total_images_in_folder = len(glob.glob1(folder_Path,"*"))

        # Select the center image for display
        self.current_image_number = round(self.total_images_in_folder / 2)
        self.display_number = self.current_image_number

        image_dtype = np.uint8
        pixel_array = np.ndarray([self.total_images_in_folder, image_height, image_width, image_depth]).astype(image_dtype)
        # load images here, once better MR images are acquired
        for image_index in range(0, self.total_images_in_folder):
            # for DICOM
            image_path = folder_Path + "/" + str(image_index) + ".dcm"

            scan_image = dicom.dcmread(image_path)
            scan_image = scan_image.pixel_array.astype(image_dtype)

            pixel_array[image_index, :scan_image.shape[0], :scan_image.shape[1], :scan_image.shape[2]] = scan_image

        return pixel_array

但得到錯誤：-

IndexError('元組索引超出范圍',)

我正在使用枕頭 python 庫作為圖像。

Answer 1

你怎么知道scan_image.shape的長度是 3？ MR 圖像應該是單色的，這會使image_depth = 1並且scan_image.shape的長度等於 2。

C.8.3.1.1.3 光度解釋

枚舉值：

• 單色1
• 單色2
