Working with Data#
Here we present some useful tips & tricks which to help working with data which has been converted using PyDicer. As you will see, working with data in PyDicer is heavily oriented around DataFrames provided by the Pandas library. If you aren’t familiar with Pandas, we recommend working through the Pandas Getting Started Tutorials.
[1]:
try:
from pydicer import PyDicer
except ImportError:
!pip install pydicer
from pydicer import PyDicer
from pathlib import Path
from pydicer.utils import (
fetch_converted_test_data,
load_object_metadata,
determine_dcm_datetime,
read_simple_itk_image
)
Setup PyDicer#
Here we load the LCTSC data which has already been converted. This is downloaded into the testdata_lctsc directory. We also initialise a PyDicer object.
[2]:
working_directory = fetch_converted_test_data("./testdata_lctsc", dataset="LCTSC")
pydicer = PyDicer(working_directory)
Working directory %s aready exists, won't download test data.
Read Converted Data#
To obtain a DataFrame of the converted data, use the read_converted_data function.
[3]:
df = pydicer.read_converted_data()
df

Iterating Over Objects#
If you want to perform some operation on (for example) all images in your dataset, you can iterate over each image row like this. Within each loop we load each image as a SimpleITK image (just for demonstration purposes).)
[4]:
for idx, ct_row in df[df.modality=="CT"].iterrows():
print(f"Loading image with hashed UID: {ct_row.hashed_uid}...", end="")
img = read_simple_itk_image(ct_row)
print(" Complete")
Loading image with hashed UID: 5adf40... Complete
Loading image with hashed UID: 88c5ef... Complete
Loading image with hashed UID: 914d57... Complete
Loading image with hashed UID: aa38e6... Complete
Loading image with hashed UID: dd0026... Complete
Loading image with hashed UID: d91c84... Complete
Loading image with hashed UID: 738c1a... Complete
Loading image with hashed UID: 6834c9... Complete
Loading image with hashed UID: 666be6... Complete
Loading image with hashed UID: 2bf2f9... Complete
Loading Object Metadata#
The metadata from the DICOM headers is stored by PyDicer and can be easily loaded using the load_object_metadata function. Simply pass a row from the converted DataFrame into this function to load the metadata for that object.
[5]:
first_row = df.iloc[0]
ds = load_object_metadata(first_row)

Loading metadata for all data objects#
You can use the Pandas apply function to load metadata for all rows and add it as a column to the converted DataFrame.
[7]:
df["StudyDescription"] = df.apply(lambda row: load_object_metadata(row, keep_tags="StudyDescription").StudyDescription, axis=1)

Determine Date of Object#
There are several DICOM header tags which could define the date of an object. The DICOM standard doesn’t require all of these to be set within the metadata. PyDicer provides the determine_dcm_datetime function to extract the date from the DICOM header.
[8]:
ds = load_object_metadata(first_row)
obj_datetime = determine_dcm_datetime(ds)
print(obj_datetime)
