Varian Halcyon Smart Linear Accelerator -- ushering in a new era of intelligent precision radiotherapy

What is the Halcyon Linear Accelerator?

The Halcyon system introduced at our hospital is the world's first high-end medical linear accelerator to achieve 100% image guidance, featuring fully digital and AI-driven radiotherapy. It offers highly integrated, highly automated, and highly intelligent capabilities, making it a powerful tool for tumor treatment, elevating radiotherapy from traditional "precise radiotherapy" to "intelligent precision radiotherapy."

World's first to achieve 100%

• Image-guided medical linear accelerator

• Optimized image-guided radiotherapy

• Next-generation dual-layer multi-leaf collimator

• High-speed, high-quality treatment

• More efficient workflow

• Patient-centered comfort and safety

• User-friendly operation

Indications for Halcyon

1. Thoracic tumors: breast cancer, lung cancer, esophageal cancer

2. Abdominal and pelvic tumors: cervical cancer, gastric cancer, prostate cancer

3. Head and neck tumors: nasopharyngeal carcinoma, intracranial tumors, thyroid cancer

4. Other complex and special types: multiple metastases, pediatric tumors, spinal metastases, benign lesions

Advantages and Features of Halcyon

1. High precision Relying on high-definition image guidance and dual-layer grids, it achieves submillimeter-precision targeting of the tumor while maximizing protection of surrounding healthy tissues.

2. High comfort The open large-aperture design combined with an ultra-quiet treatment couch significantly reduces patient claustrophobia and enhances physical and mental comfort during treatment.

3. High speed With an extremely fast gantry rotation, a single treatment takes only 3--5 minutes, effectively reducing errors caused by organ motion and improving patient throughput.

4. High treatment quality Through volumetric rotational intensity-modulated therapy and stereotactic radiotherapy techniques, the tumor dose distribution is optimized, significantly improving local tumor control.

5. High intelligence The fully automated workflow guides the entire treatment process from positioning to delivery, greatly simplifying operations and reducing human errors.

6. High efficiency The integrated design and fast workflow allow for treating more patients per day, significantly enhancing departmental equipment utilization.

7. High image quality High-definition 3D images are acquired before each treatment, providing excellent soft tissue resolution to ensure precise and reliable position verification.
