PixelDataHeader

core.pixel_header.PixelDataHeader(
    RescaleSlope=1.0,
    RescaleIntercept=0.0,
    OriginalPixelDtype='uint16',
    PixelDtype='uint16',

)

Header class for storing pixel data information in medical images.

Stores metadata including: - Rescale factors (slope/intercept) - Original pixel data type - Window settings (center/width) - Value range (min/max) - Additional metadata in extras

Attributes: RescaleSlope (float): Slope for linear transformation. RescaleIntercept (float): Intercept for linear transformation. PixelDtype (str): Pixel data type string (after convert to dcb file). OriginalPixelDtype (str): Original pixel data type string (before convert to dcb file). WindowCenter (float, optional): Window center value for display. WindowWidth (float, optional): Window width value for display. MaxVal (float, optional): Maximum pixel value. MinVal (float, optional): Minimum pixel value. Extras (Dict[str, any]): Dictionary for additional metadata.

Methods

Name	Description
from_dict	Create a PixelDataHeader from a dictionary.
from_json	Create a PixelDataHeader from a JSON string.
to_dict	Convert the header to a dictionary for serialization.
to_json	Serialize the header to a JSON string.

from_dict

core.pixel_header.PixelDataHeader.from_dict(d)

Create a PixelDataHeader from a dictionary.

Args: d (dict): Dictionary containing header data.

Returns: PixelDataHeader: A new instance with values from the dictionary.

from_json

core.pixel_header.PixelDataHeader.from_json(json_str)

Create a PixelDataHeader from a JSON string.

Args: json_str (str): JSON string containing header data.

Returns: PixelDataHeader: A new instance created from the JSON data.

to_dict

core.pixel_header.PixelDataHeader.to_dict()

Convert the header to a dictionary for serialization.

Merges extras field into the main dictionary and removes the redundant extras key.

Returns: dict: Dictionary representation of the header.

to_json

core.pixel_header.PixelDataHeader.to_json()

Serialize the header to a JSON string.

Returns: str: JSON string representation of the header.
