DICOM Preprocessing

Parse DICOM headers, extract pixel data, and apply windowing. The parsing loop compiles efficiently.

def apply_window(pixels, window_center, window_width):
    min_val = window_center - window_width // 2
    max_val = window_center + window_width // 2
    result = []
    for row in pixels:
        out = []
        for val in row:
            if val < min_val:
                out.append(0)
            elif val > max_val:
                out.append(255)
            else:
                out.append(int((val - min_val) / window_width * 255))
        result.append(out)
    return result

Feature Extraction

Texture, intensity, and shape features for radiomics.

Segmentation Post-Processing

Connected components, contour extraction, and mask refinement.
