你可以使用Python中的pydicom库来实现将多个DCM图像融合为一张窗宽为(768,1024)的DCM图像。下面是一个示例代码:
```python
import numpy as np
import pydicom
from pydicom.pixel_data_handlers.util import apply_voi_lut
# 读取文件夹中的所有DCM图像
folder_path = r'C:\Users\11508\Desktop\568'
file_paths = pydicom.dcmread(folder_path)
# 获取图像的像素数据和窗宽窗位信息
pixel_data = []
window_center = []
window_width = []
for file_path in file_paths:
ds = pydicom.dcmread(file_path)
pixel_data.append(ds.pixel_array)
window_center.append(ds.WindowCenter)
window_width.append(ds.WindowWidth)
# 计算窗宽窗位的平均值
avg_window_center = np.mean(window_center)
avg_window_width = np.mean(window_width)
# 应用窗宽窗位和融合像素数据
merged_pixel_data = np.zeros_like(pixel_data, dtype=np.int16)
for i in range(len(pixel_data)):
merged_pixel_data += apply_voi_lut(pixel_data[i], window_center[i], window_width[i])
# 创建新的DCM文件并保存融合后的像素数据
merged_ds = pydicom.dcmread(file_paths)
merged_ds.Rows, merged_ds.Columns = merged_pixel_data.shape
merged_ds.PixelData = merged_pixel_data.tobytes()
merged_ds.WindowCenter = avg_window_center
merged_ds.WindowWidth = avg_window_width
output_path = r'C:\Users\11508\Desktop\merged.dcm'
merged_ds.save_as(output_path)
print('图像融合完成,并保存为{}'.format(output_path))
```
请确保已经安装了pydicom库,并将文件夹路径替换成你实际的文件夹路径。这段代码会将文件夹中的所有DCM图像融合为一张窗宽为(768,1024)的DCM图像,并保存在指定的输出路径。
