Abstract
Description
[0001] Integrated Multimodal Al Hospital Platform with Autonomous Screening Interval Generation, Digital-Twin-Driven Therapy Optimization, and Closed-Loop Cancer Management System TECHNICAL FIELD
[0002] This invention relates to artificial intelligence systems for oncology, cardiovascular diseases, autonomous hospital management, precision diagnostics, personalized prevention care, and adaptive treatment optimization. The present invention relates to healthcare systems and medical informatics, specifically to an integrated Al platform that combines predictive Al analytics, preventive interventions, genetic counseling, intelligent screening, automated care pathways, and patient engagement for comprehensive healthcare delivery.
[0003] BACKGROUND
[0004] Cancer and cardiovascular diseases remain the leading causes of morbidity and mortality worldwide. Despite remarkable advancements in molecular diagnostics, immunotherapy, targeted therapy, and minimally invasive surgery, the global burden continues to rise, particularly due to delayed detection, inconsistent screening adherence, limited access to specialized oncologic care, and the complexity of clinical decision-making across heterogeneous patient populations. Traditional healthcare infrastructures face persistent challenges in providing timely, consistent, and high-quality care, especially in low-resource settings, geographically dispersed populations, and institutions experiencing shortages of specialists.
[0005] Conventional care systems typically operate in linear, fragmented workflows. Screening programs rely on fixed-interval protocols rather than personalized risk-adjusted schedules. Diagnostic evaluation often requires manual correlation between radiology, pathology, molecular profiling, and clinical data, resulting in delays and variability in interpretation. Treatment planning is similarly fragmented: oncologists must synthesize large volumes of multimodal data to determine optimal therapy regimens, yet existing electronic medical record (EMR) systems provide limited computational support, and conventional decision-support tools lack integration across modalities. Predicting treatment response or toxicity often depends on subjective clinical judgment, and there is no real-time simulation model that represents the dynamic biological evolution of tumors under different treatment strategies.
[0006] Artificial intelligence (Al) has emerged as a promising solution to several components of cancer care. Deep learning algorithms have demonstrated high accuracy in radiology interpretation, pathology slide analysis, and genomic variant classification. Machine-learning-based prognostic models have been introduced for specific cancers. However, these Al systems are typically narrow, task-specific, and siloed; they do not operate as cohesive, generalizable frameworks capable of managing the entire cancer care continuum. Most importantly, current Al approaches do not provide a unified, multimodal patient representation that integrates all available clinical, biological, and imaging data. They also lack the capability to autonomously plan screening schedules, simulate disease progression, optimize therapeutic strategies, or coordinate hospitallevel workflows.
[0007] Digital twin technologies, widely explored in industrial and engineering domains, have only recently entered biomedical research. Initial medical digital twins focus predominantly on cardiovascular physiology, orthopedic biomechanics, or critical care patient monitoring. While the conceptual promise of digital twins in oncology has been discussed, there is no clinically deployed system capable of generating dynamic, patient-specific cancer models that update continuously with new multimodal data and guide real-time therapy optimization. Existing cancer models are static, single-modality, and not integrated with clinical decision systems.
[0008] Furthermore, healthcare delivery systems lack closed-loop architectures. A closed-loop system requires: (1) continuous data intake, (2) computational interpretation, (3) automated action recommendations, (4) outcome measurement, and (5) recalibration. Current medical infrastructures do not support such iterative feedback cycles. Screening programs are static rather than adaptive; diagnosis is episodic rather than continuous; treatment planning is reactive rather than predictive; and follow-up monitoring is manual rather than model-driven.
[0009] In addition, hospitals face operational challenges in maintaining timely and coordinated oncology services. Radiology and pathology departments often operate independently. Genomic laboratories may deliver results in formats that clinicians struggle to integrate. Tumor boards are time-limited and resource-intensive, leading to delays in complex cases. Clinical guidelines (e.g., NCCN, ESMO, ASCO) are updated frequently, yet physicians must manually interpret and apply these updates in each case. As cancer datasets grow exponentially, clinicians increasingly rely on experience and heuristics rather than systematic data-driven guidance.
[0010] Thus, there is an urgent need for a holistic, integrated, Al-driven platform capable of supporting — and in some components autonomously executing — the entire cancer care spectrum from prevention and personalized screening through diagnosis, treatment selection, and longitudinal monitoring. Such a platform must integrate multimodal data, operate at hospital scale, and enable real-time decision-making. It must incorporate predictive modelling, digital-twin simulation, risk stratification, and adaptive treatment optimization. It must operate as a closed-loop ecosystem that continuously learns from patient outcomes and refines its predictions and recommendations. Despite rapid development in Al, no existing system delivers:
[0011] (1) unified multimodal oncology representation;
[0012] (2) personalized autonomous screening interval generation;
[0013] (3) real-time patient-specific digital twin modeling;
[0014] (4) reinforcement-learning-based adaptive therapy optimization;
[0015] (5) integration across hospital infrastructures including PACS, LIS, EMR, genetic labs, and remote sensors;
[0016] (6) a fully closed-loop management framework.
[0017] Accordingly, there remains a significant unmet need for an integrated platform capable of providing comprehensive precision oncology care across prevention, screening, diagnosis, therapy design, monitoring, and recurrence prediction. The background barriers include fragmented workflows, incompatible software systems, absence of multimodal fusion, limited automation, and a lack of predictive, simulation-driven clinical intelligence. Addressing this gap requires an invention that combines Al models, system-level orchestration, digital-twin technology, and clinical guidelines into a scalable, operational, and industrial hospital framework.
[0018] SUMMARY
[0019] This invention introduces a first-of-its-kind Al-driven autonomous ecosystem that operates across the entire cancer care continuum. Unlike existing standalone Al diagnostic models, this invention defines a fully integrated Al hospital architecture for oncology, cardiovascular diseases, and non- communicative diseases, consisting of the following novel components: 1.

[0024] • Laboratory markers
[0025] • Electronic medical records
[0026] • Wearable and lifestyle data
[0027] The fusion occurs inside a single joint latent space, not a pipeline of separate models.
[0028] 2. Autonomous Screening Interval Generator (ASIG)
[0029] • An engine that calculates dynamic, real-time, personalized screening intervals for cancer (e.g., breast, lung, colorectal) using:
[0030] • Individual risk profiles
[0031] • Polygenic risk
[0032] • Environmental exposures
[0033] • Prior imaging
[0034] • Social determinants
[0035] • Al-predicted tumor evolution
[0036] 3. Digital Twin Engine (DTE)
[0037] The system builds a dynamic cancer digital twin that continuously models:
[0038] • Tumor progression
[0039] • Treatment response
[0040] • Metastasis probability
[0041] • Toxicity risks
[0042] • Survival probabilities
[0043] The digital twin updates with each new data entry.
[0044] 4. Adaptive Therapy Optimization Engine (ATOE)
[0045] • A reinforcement-learning treatment engine that:
[0046] • Simulates multiple therapy trajectories
[0047] • Evaluates toxicity, cost, accessibility
[0048] • Predicts expected response using the digital twin
[0049] • Recommends optimal therapy sequences
[0050] 5. Autonomous Clinical Pathway Generator (ACPG) — Novelty
[0051] • Generates step-by-step oncology management workflows:
[0052] • Screening — Diagnostic — Staging — Treatment
[0053] • Predictive follow-up plan
[0054] • Alerting and tumor board automation
[0055] 6. Hospital-Level Al Orchestration Layer (H-AIOL) — Industrial Step
[0056] • Integrates all subsystems across:
[0057] • Radiology PACS
[0058] • Pathology LIS
[0059] • Oncology EMR Operating rooms
[0060] Pharmacy
[0061] National registries
[0062] BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The proposed Al hospital platform is a comprehensive, integrated system that unites predictive analytics, automated care pathways, genetic counseling, intelligent imaging, laboratory analysis, and patient engagement. Unlike conventional Al healthcare tools, which are siloed and domainspecific, this platform leverages multi-modal data fusion to generate personalized, preventive, and adaptive care across multiple disease domains, including oncology, cardiovascular diseases, diabetes, and other non-communicable diseases (NCDs).
[0065] The system is structured into seven core modules:
[0066] • Data Ingestion and Preprocessing Module
[0067] • Predictive Analytics Engine
[0068] • Diagnostic Imaging Module
[0069] • Genetic Counseling Module
[0070] • Automated Care Pathways Module
[0071] • Patient Engagement Module
[0072] • Adaptive Learning & Feedback Loop
[0073] Each module operates independently yet communicates seamlessly with the others, creating a closed-loop ecosystem capable of continuous improvement.
[0074] 2. Data Ingestion and Preprocessing Module
[0075] 2.1 Multi-modal Data Collection
[0076] • The platform collects and stores multiple types of patient data:
[0077] • Structured Clinical Data: Demographics, vital signs, comorbidities, medication history • Laboratory Data: Hematology, biochemistry, microbiology, pathology results
[0078] • Genetic Data: SNP panels, whole-exome sequencing, polygenic risk scores
[0079] • Medical Imaging Data: Radiology (CT, MRI, X-ray), histopathology slides
[0080] All data is encrypted and stored in a centralized, HIPAA-compliant database, ensuring both security and accessibility for Al model training.
[0081] 2.2 Data Cleaning and Normalization
[0082] To maximize Al performance, preprocessing involves:
[0083] • Imputation of missing values using K-nearest neighbors or matrix completion methods • Scaling continuous variables (e.g., blood pressure, BMI) to zero mean and unit variance • Encoding categorical variables with one-hot encoding or embedding layers for neural networks
[0084] • Image augmentation: rotations, flips, contrast adjustment, Gaussian noise injection PyTorch Example: Clinical Data Normalization
[0085] import torch
[0086] import pandas as pd
[0087] import numpy as np
[0088] clinical_df = pd.read_csv("clinical_data.csv")
[0089] features = clinical_df[['age','bmi','blood_pressure']].values
[0090] features = (features - features.mean(axis=0)) / features.std(axis=0)
[0091] clinical_tensor = torch.tensor(features, dtype=torch.float32)
[0092] PyTorch Example: Image Preprocessing
[0093] from torchvision import transforms
[0094] image_transforms = transforms.Compose([
[0095] transforms.Resize((224,224)),

[0097] transforms.RandomRotation(15),
[0098] transforms.ToTensor(),
[0099] transforms.Normalize(mean=[0.485,0.456,0.406],
[0100] std=[0.229,0.224,0.225])
[0101] ])
[0102] 2.3 Feature Extraction and Encoding
[0103] • Clinical and lab features are passed through a dense embedding network
[0104] • Genetic features (SNPs, polygenic risk scores) are encoded using linear layers or autoencoders
[0105] • Image embeddings are generated using CNNs or Vision Transformers
[0106] Example: Genetic Embedding
[0107] genetic_data = torch.randn(clinical_tensor.shape[0], 1000) # Example SNPs
[0108] genetic_embedding_layer = torch.nn.Linear(1000, 64)
[0109] genetic_embedding = genetic_embedding_layer(genetic_data)
