        # What is PortPy?
        
        PortPy, short for **P**lanning and **O**ptimization for **R**adiation **T**herapy, represents a collective effort 
        to establish an open-source Python library dedicated to advancing the development and clinical implementation of 
        cancer radiotherapy treatment planning algorithms. This initiative encompasses planning methodologies for 
        Intensity Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT), along with other 
        emerging modalities. PortPy provides clinical-grade data and coding resources that foster *benchmarking*, 
        *reproducibility*, and *community development*.
        
        **Note:** In the near future, we plan to launch an educational YouTube channel to assist 
        researchers new to this field. Meanwhile, we suggest reviewing relevant literature review papers
        ([Zarepisheh et al. 2021](https://pubsonline.informs.org/doi/abs/10.1287/inte.2021.1095),

        A key limitation of existing open-source packages in radiotherapy treatment planning is their
        inability to objectively evaluate new treatment planning techniques against current clinical practices. 
        This limitation stems from the difficulty in fully replicating clinical environments, such as detailed 
        linear accelerator configurations and commercial dose calculation engines. Consequently,
        plans generated using novel techniques, such as AI-based automated treatment planning, cannot be objectively compared
        with clinical plans used in patient treatment. To address this limitation, we are integrating PortPy with 
        commercial treatment planning systems (TPSs). PortPy is already compatible with the [Varian Eclipse TPS](https://www.varian.com/), 
        and we plan to expand compatibility to additional TPSs in the future. It's crucial to note that PortPy can 
        be used independently of any TPS, but accessing a TPS is essential for final evaluation within the TPS (see above figure).
        <p align="center">

        <p>
        
        Above figure highlights the inspiration for developing PortPy, drawing on successful open-source practices 
        from the AI and computer science communities. Tools like PyTorch and TensorFlow, along with benchmark datasets 
        such as ImageNet and algorithms like AlexNet, have transformed AI and data science. Our aim is to emulate 
        this success, providing researchers with comprehensive resources (PortPy integration with commercial TPS 
        and other renowned open-source tools such as [3DSlicer](https://www.slicer.org/) and [CVXPy](https://www.cvxpy.org/), a benchmark dataset 
        (featuring 50 curated lung patients with expertly selected beams, all necessary optimization data, 
        and benchmark IMRT plans created using our in-house automated planning system, ECHO), 
        and benchmark algorithms, including Mixed Integer Programming (MIP) algorithms for achieving globally optimal solutions.

        PortPy facilitates the **design**, **testing**, and **clinical validation** of new treatment planning algorithms. 
        This includes both cutting-edge AI-based models and traditional optimization techniques. 
        The above figure illustrates the PortPy design and its three main
        modules: “Data Management”, “Plan Generation”, and “Plan
        Evaluation”,  which are discussed below. We recommend reviewing our Jupyter Notebooks 
        examples for a more comprehensive understanding of these modules. 
        
        1. **Data Management**
             * This module provides access to the curated benchmark PortPy dataset, which currently comprises data from 50 lung patients.
        It allows researchers to test and develop their algorithms using the same dataset (see [basic_tutorial.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/1_basic_tutorial.ipynb) notebook)
             * The available data includes: 1) CT images and contours, 2) all necessary data for optimization extracted from 
        Eclipse using its API (version 16.1), 3)expert-selected beams for each patient, 4) an IMRT plan for each patient, 
        generated using our in-house automated planning system, 
        ECHO ([YouTube Video](https://youtu.be/895M6j5KjPs), [Paper](https://aapm.onlinelibrary.wiley.com/doi/epdf/10.1002/mp.13572)).
        More information about data can be found in [Data](#Data) section.
             * In the current version, you can only work with the benchmark dataset provided in this PortPy repo and 
           cannot use your own dataset for now. We will address this problem in the near future
        
        2. **Plan Generation**
             * This module facilitates the generation of treatment plans using either classical optimization methods or 
        emerging AI-based techniques 
             * For optimization tasks, PortPy has been integrated with [CVXPy](https://www.cvxpy.org/), a widely-used open-source package. 
        CVXPy enables the high-level formulation of optimization problems and offers out-of-the-box access to a range
        of free (e.g., [SCIP](https://www.scipopt.org/), [SCIPY](https://docs.scipy.org/doc/scipy/reference/optimize.html)) and commercial (e.g., [MOSEK](https://www.mosek.com/), [CPLEX](https://www.ibm.com/products/ilog-cplex-optimization-studio/cplex-optimizer), [GUROBI](https://www.gurobi.com/)) optimization engines (available for free for research
        purposes) (see [basic_tutorial.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/1_basic_tutorial.ipynb) notebook)
             * PortPy.AI module is equipped with essential functionalities for AI-based planning. These include data access, 
        data pre-processing, model training and testing, and patient-specific 3D dose prediction 
        (see [dose_prediction_pipeline.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/AI_tutorials/dose_prediction_pipeline.ipynb) notebook)
             * The availability of both optimization and AI-based planning modules within PortPy allows researchers 
        to not only compare these techniques but also explore their complementary aspects
        
        3. **Plan Visualization and Evaluation**
             * Basic built-in visualization tools (e.g., DVH, dose distribution) are integrated into PortPy 
             * Enhanced visualizations are available through the integration with the popular open-source [3DSlicer](https://www.slicer.org/) package (see [3d_slicer_integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/3d_slicer_integration.ipynb) notebook)
             * PortPy IMRT plans with optimal fluence can be imported into Eclipse for leaf sequencing and final clinical evaluations  (see [eclipse_integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/eclipse_integration.ipynb))
             * PortPy IMRT/VMAT plans with optimal control points can be imported into any FDA approved TPS ( e.g. Eclipse, Raystation) using DICOM RT Plan file for final clinical evaluations  (see [TPS-integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/TPS-Integration.ipynb)).
        It should be noted that some discrepancies are anticipated 
        with TPSs other than Eclipse, due to the fact that our current data are derived from Eclipse, and there 
        may exist variations in dose calculation methods between Eclipse and other TPSs. 
             * Plans can also be evaluated within PortPy using well-established clinical protocols (e.g., Lung 2Gyx30, see  [basic_tutorial.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/1_basic_tutorial.ipynb))
             * Future updates will include more standardized RTOG metrics and outcome models (TCP/NTCP)

        1. To grasp the primary features of PortPy, we highly recommend exploring the [basic_tutorial.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/1_basic_tutorial.ipynb) notebook
        2. To understand how to import a PortPy plan into Eclipse for final evaluations, browse through the [eclipse_integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/eclipse_integration.ipynb) notebook
        3. To create dicom RT Plan file from PortPy plan and import into FDA approved commercial TPS (e.g. Eclipse, Raystation), please browse through [TPS-integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/TPS-Integration.ipynb) notebook
        4. To learn about enhanced visualization techniques using the 3D-Slicer package, refer to the  [3d_slicer_integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/3d_slicer_integration.ipynb) notebook
        5. For algorithm benchmarking, the global optimal solutions are provided for non-convex optimization problems resulting from beam angle optimization [beam_orientation_optimization.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/benchmark_algorithms/beam_orientation_optimization.ipynb), incorporating DVH constraints [dvh_constraint_optimization.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/benchmark_algorithms/dvh_constraint_optimization.ipynb), and VMAT optimization [vmat_optimization.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/benchmark_algorithms/vmat_optimization.ipynb) using the mixed-integer programming on down-sampled data.
        6. If you encounter computational challenges with large-scale optimization problems, you can opt for down-sampling the voxels/beamlets, as illustrated in the [down_sampling](https://github.com/PortPy-Project/PortPy/blob/master/examples/advanced_tutorials/down_sampling.ipynb) notebook, or further sparsify the influence matrix, as demonstrated in the [inf_matrix_sparsification](https://github.com/PortPy-Project/PortPy/blob/master/examples/advanced_tutorials/inf_matrix_sparsification.ipynb) notebook.

        PortPy equips researchers with a robust benchmark patient dataset, sourced from the FDA-approved Eclipse commercial treatment planning system through its API. This dataset embodies all necessary elements for optimizing various machine configurations such as beam angles, aperture shapes, and leaf movements. It includes
        
        1. **Dose Influence Matrix (AKA dose deposition matrix, dij matrix):** The dose contribution of each beamlet to each voxel,
        2. **Beamlets/Voxels Details:** Detailed information about the position and size of beamlets/voxels,
        3. **Expert-Selected Benchmark Beams:** An expert clinical physicist has carefully selected benchmark beams, providing reference beams for comparison and benchmarking,
        4. **Benchmark IMRT Plan:** A benchmark IMRT plan generated using our in-house automated treatment planning system called ECHO ([YouTube Video](https://youtu.be/895M6j5KjPs), [Paper](https://aapm.onlinelibrary.wiley.com/doi/epdf/10.1002/mp.13572)). This plan serves as a benchmark for evaluating new treatment planning algorithms.
        5. **Benchmark Clinical Criteria:** A set of clinically relevant mean/max/DVH criteria for plan evaluation. 
        Currently, this set encompasses only the Lung 2Gy×30 protocol but will be expanded in the future to more protocols as well as TCP/NTCP evaluation functions.  
        
        To access these resources, users are advised to download the latest version of the dataset, 
        which can be found [here](https://drive.google.com/drive/folders/1nA1oHEhlmh2Hk8an9e0Oi0ye6LRPREit?usp=sharing). 
        Subsequently, create a directory titled './data' in the current project directory and transfer the downloaded 
        file into it. For example, ./data/Lung_Phantom_Patient_1. 
        We have adopted the widely-used JSON and HDF5 formats for data storage.
        [HDFViwer](https://www.hdfgroup.org/downloads/hdfview/) can be utilized to view the contents of the HDF5 files.  
        
        
        
        **Note:** Initially, we will utilize a lung dataset from [TCIA](https://wiki.cancerimagingarchive.net/display/Public/NSCLC-Radiomics). The original DICOM CT images and structure sets are not included in the PortPy dataset and need to be directly downloaded from the TCIA. Users can fetch the **TCIA collection ID** and the **TCIA subject ID** for each PortPy patient using the *get_tcia_metadata()* method in PortPy and subsequently download the data from TCIA (see [eclipse_integration.ipynb](https://github.com/PortPy-Project/PortPy/blob/master/examples/eclipse_integration.ipynb))
