How can i combine or concatenated generated multiple series of DICOM image into single frame?

Hi there,
I am looking for some suggestion regarding my problem.
I was able to convert a number of png image into DICOM and now I want to concatenate them into a single frame. How can I achieve that?
Any suggestion

Just do the normal numpy array concatenation.

arr1 = np.asarray([[1, 2], [3, 4]])
arr2 = np.asarray([[5, 6], [7, 8]])

arr = np.concatenate((arr1, arr2), axis=1)
ds.Rows, ds.Columns = arr.shape
ds.PixelData = arr.tobytes()
# etc...

Hi there,
You mean to say I should concatenate before generating multiple series DCM files or after generating multiple series files.
I am following below code:

import numpy as np
import pydicom
import os
from natsort import natsorted

Multiple_series_DICOM_Image = "/home/Channel_-01-0/"
Single_frame_DICOM_Image = "/home/Single_frame_output/"
# Read a dicom multiple series files one by one
iii = []
names = os.listdir(Multiple_series_DICOM_Image)
# names = natsorted(names)
names = sorted(names, key=lambda i: int(os.path.splitext(os.path.basename(i))[0]))
for file_name in names:
    if file_name.endswith(".dcm"):
        filename, file_extension = os.path.splitext(file_name)
        dicom_meta = pydicom.dcmread(Multiple_series_DICOM_Image + "/" + file_name, force=True)
        image_dcm = dicom_meta.pixel_array
        # arr = np.concatenate(image_dcm)
        iii.append(image_dcm)

But I couldn't understand how can I add 120 images pixe_array

I have no idea what you're trying to do, so 🤷‍♂️
