How to Convert DICOM to PDF

Python developers can easily load & convert DICOM files to PDF in just a few lines of code.

  1. Define the paths to the input PDF file and output directory using path.join() function.
  2. Use pydicom library to load the DICOM image file from disk, specifying its file path using the dcmread() function. This step loads the entire DICOM image into memory.
  3. Extract the number of rows and columns from the loaded DICOM image using its Rows and Columns attributes, which represent the size of the image in pixels.
  4. Print a message to the console indicating the size of the loaded DICOM image in pixels, displaying its rows and columns.
  5. Create a new instance of the Document class from aspose.pdf library to create an empty PDF document. This step initializes the document with no pages or content.
  6. Use the add() method of the Document’s pages collection to add a new page to the document, which will be used as a container for the DICOM image.
  7. Create a new instance of the Image class from aspose.pdf library to represent the loaded DICOM image. This step sets up the image with its file type and content.
  8. Set the height, width, and margins (top, bottom, right, left) of the new page using various properties of the PageInfo object to match the size of the loaded DICOM image. This step ensures proper layout and positioning.
  9. Use the add() method of the Page’s paragraphs collection to add the loaded DICOM image as a paragraph to the new page, which will be rendered as an image in the PDF document. This step adds content to the document.
  10. Use the save() method of the Document object to write the completed PDF document to disk, specifying its file path using the outfile variable. This step finalizes the document and saves it to disk.

Here is an example that demonstrates how to convert DICOM to PDF in Python. You can follow these easy steps to convert your DICOM file to PDF format. First, upload your DICOM file and then simply save it as a PDF file. You can use fully qualified filenames for both DICOM reading and PDF writing. The output PDF content and formatting will be identical to the original DICOM document.

Example: Convert DICOM to PDF via Python

This sample code shows DICOM to PDF Python Conversion

Input file:

File not added

Output format:

PDF

Output file:

import aspose.pdf as apdf

from os import path
import pydicom

path_infile = path.join(self.data_dir, infile)
path_outfile = path.join(self.data_dir, outfile)

# Load the DICOM file
dicom_file = pydicom.dcmread(path_infile)

# Get the dimensions of the image
rows = dicom_file.Rows
columns = dicom_file.Columns

# Print the dimensions
print(f"DICOM image size: {rows} x {columns} pixels")

# Initialize new Document
document = apdf.Document()
page = document.pages.add()
image = apdf.Image()
image.file_type = apdf.ImageFileType.DICOM
image.file = path_infile

# Set page dimensions

page.page_info.height = rows
page.page_info.width = columns
page.page_info.margin.bottom = 0
page.page_info.margin.top = 0
page.page_info.margin.right = 0
page.page_info.margin.left = 0
page.paragraphs.add(image)

document.save(path_outfile)
print(infile + " converted into " + outfile)
