Я предварительно обрабатываю хранилище изображений DICOM, чтобы передать ему сверточную нейронную сеть, но когда я пытаюсь прочитать хранилище, он выдает следующую ошибку:
LookupError: неизвестная кодировка: ISO 2022ИК 100
Вот код, который я использовал:
listoflists = []
list = []
for x in range(1, 10):
data_path = "/home/lorenzo_f/CT COLONOGRAPHY/1.3.6.1.4.1.9328.50.4.000%d" %x
output_path ="/home/lorenzo_f/output/"
subfolders = [f.path for f in os.scandir(data_path) if f.is_dir() ]
subfolder = [f.path for f in os.scandir(subfolders[0]) if f.is_dir() ]
list.append(load_scan(subfolder[0]))
list.append(load_scan(subfolder[1]))
listoflists.append((list))
Использование функции load_scan
# Loop over the image files and store everything into a list.
def load_scan(path):
slices = [dicom.read_file(path + '/' + s) for s in os.listdir(path)]
#slices[0].SpecificCharacterSet = 'latin_1'
slices.sort(key = lambda x: int(x.InstanceNumber))
try:
slice_thickness = np.abs(slices[0].ImagePositionPatient[2] - slices[1].ImagePositionPatient[2])
except:
slice_thickness = np.abs(slices[0].SliceLocation - slices[1].SliceLocation)
for s in slices:
s.SliceThickness = slice_thickness
return slices
Я не могу найти тег, которым вы являетесьговоря, это код, который я использовал, и первая запись вывода
