AI-powered auto contouring in radiotherapy depends on one critical foundation: accurately annotated medical imaging data.

For healthcare AI companies developing radiotherapy auto-contouring, radiation oncology AI, treatment-planning tools, and medical image segmentation models, high-quality annotations of anatomical structures, Organs at Risk (OARs), and target regions are essential.

Srishta Technology Private Limited provides specialized radiotherapy data annotation services for healthcare AI, helping organizations convert CT, MRI, and other medical imaging datasets into structured, quality-controlled AI training data.

What Is Radiotherapy Data Annotation?

Radiotherapy data annotation involves identifying and segmenting anatomical structures and treatment-related regions within medical images for AI development, research, and radiation oncology applications.

Depending on project requirements, annotation can include:

• Organs at Risk (OAR) segmentation
• Anatomical structure segmentation
• Tumor segmentation
• GTV contouring
• CTV contouring
• PTV contouring
• CT scan annotation and contouring
• MRI annotation
• Region-of-interest segmentation
• DICOM-based medical imaging workflows

These annotated datasets can support the development and evaluation of AI auto-contouring and radiation oncology computer vision systems.

OAR Segmentation Services for Radiotherapy AI

Organ at Risk annotation is an important component of many radiotherapy auto-contouring datasets.

Depending on the anatomical region and client guidelines, OAR segmentation may involve structures such as:

• Spinal cord
• Brainstem
• Parotid glands
• Lungs
• Heart
• Esophagus
• Liver
• Kidneys
• Bladder
• Rectum

Srishta Technology can provide OAR segmentation services according to client-defined structure lists, contouring protocols, and quality requirements.

GTV, CTV and PTV Contouring Annotation

Some radiation oncology datasets require target-volume annotation.

Depending on project scope and required clinical expertise, annotation workflows can support:

GTV – Gross Tumor Volume
CTV – Clinical Target Volume
PTV – Planning Target Volume

These annotations can be prepared according to the client’s clinical guidelines and project-specific contouring protocol.

Why Choose Srishta Technology for Radiotherapy Data Annotation?

Radiotherapy annotation requires more than general image labeling.

Srishta Technology can build domain-expert medical annotation workflows involving appropriately qualified medical professionals where required by the project.

Our typical workflow includes:

Guideline Review → Pilot Annotation → Client Calibration → Production Contouring → Multi-Level QA → Medical Expert Review Where Required → Delivery

Why Srishta Technology?

• Medical domain-focused annotation
• Auto-contouring data annotation
• OAR segmentation
• CT and MRI medical image annotation
• GTV, CTV and PTV workflows where applicable
• Client-specific contouring guidelines
• Human-in-the-loop annotation
• Multi-level quality assurance
• Scalable annotation teams
• Pilot annotation before large-scale production

Instead of asking clients to commit immediately to a large dataset, we can begin with a pilot annotation project so quality, accuracy, and guideline understanding can be evaluated first.
