In which diseases can it be used?

The Halcyon Radiotherapy System offers a versatile and effective solution for a wide range of cancer treatment. Its precision targeting and rapid treatment capabilities make it a reliable choice for various tumors. For instance, in prostate cancer, it excels at minimizing side effects by reducing radiation exposure to nearby sensitive organs. With breast cancer, it stands out for its ability to focus radiation on the target while sparing the heart and lungs.

Similarly, for lung cancer, its advanced targeting capabilities ensure healthy lung tissue is maximally protected while effectively managing tumor motion. The system’s high accuracy is also crucial for complex cases like head-and-neck, gynecological, brain, and colorectal cancers, where preserving critical structures and neurological functions is paramount. This broad application allows for personalized, high-standard treatment options for patients.

Which method is used for the Halcyon Radiotherapy System?

The Halcyon Radiotherapy System uses advanced techniques for precise and efficient radiation therapy. It primarily employs image-guided IMRT (Intensity-Modulated Radiation Therapy), a method that adjusts the intensity of radiation beams. This allows a high dose of radiation to be shaped precisely to the tumor while sparing nearby healthy tissues.

Additionally, the system utilizes VMAT (Volumetric Modulated Arc Therapy). With VMAT, the machine rotates around the patient, delivering the treatment much faster and from multiple angles. This approach shortens treatment sessions to just a few minutes, significantly improving patient comfort.

How is it applied?

The Halcyon Radiotherapy Treatment process is built on patient comfort and treatment precision. First, the patient is comfortably positioned on the treatment table using special beds and supports. This preparation ensures the patient remains still throughout the treatment, guaranteeing that the radiation reaches the target with millimeter precision.

Just before the treatment, a quick imaging scan of about 15 seconds is performed to verify the position of the targeted area. The resulting images are compared with the treatment plan to ensure the most accurate targeting, and any potential positional changes are corrected instantly. After this verification, the treatment begins. The device silently rotates around the patient, directing radiation beams to the designated area. The patient does not feel any pain or discomfort during this process. The very short Halcyon Radiotherapy Treatment sessions enhance patient compliance and allow them to return to their daily lives more quickly.

How long does the application/procedure take?

With the Halcyon Radiotherapy System, treatment duration is a key factor in patient comfort. The actual radiation delivery time is remarkably short, typically lasting only about two minutes, which is a significant advantage compared to conventional systems. Moreover, the total time from when the patient enters the room to when they leave, including positioning and imaging, is also greatly reduced. This efficient process makes the treatment experience less stressful and allows patients to return to their daily routines more quickly. The system’s integrated imaging and automatic positioning capabilities are central to achieving this speed and efficiency.

Is the Halcyon Radiotherapy System procedure painful?

No, the procedure is completely painless. The experience is very similar to getting an X-ray; patients do not see, hear, or feel the radiation during the treatment. The system operates quietly as it moves around you, and aside from the initial positioning on the treatment table, the process is not physically uncomfortable. The entire session is designed for maximum comfort and minimal stress, making the treatment easy to tolerate.

Which patients is it applied to?

The Halcyon Radiotherapy System is particularly suitable for patients whose tumors are located near sensitive organs requiring protection, such as the spinal cord, heart, or lungs. In these cases, which often include head-and-neck, prostate, or breast cancers, the system’s high precision offers a major advantage by minimizing radiation exposure to healthy tissue. This targeted approach helps to reduce side effects while maintaining treatment effectiveness.

However, every patient’s situation is unique. The final decision regarding the suitability of Halcyon treatment is always made by the radiation oncology team after a thorough evaluation of the patient’s overall condition and the specific characteristics of the tumor.

Who is not suitable for the Halcyon Radiotherapy System application?

The decision on whether the Halcyon Radiotherapy System is appropriate for a patient can only be made by a radiation oncologist. Although the system is highly versatile, it may not be the best choice for every case. For example, patients who have previously received high-dose radiation therapy to the same anatomical region may not be suitable candidates. Additionally, certain medical conditions or specific tumor characteristics might make other treatment methods more appropriate. A thorough evaluation of each patient’s unique health status is crucial to determine the most effective and safest treatment plan.

What are the advantages?

The Halcyon Radiotherapy System offers several key benefits that enhance the cancer treatment experience and improve therapeutic outcomes. Its advanced design focuses on precision, speed, comfort, and safety.

• Precision: It delivers high accuracy in targeting cancerous cells while meticulously protecting surrounding healthy tissues. This approach minimizes potential side effects and preserves critical organ function.
• Speed: Treatment sessions are significantly shorter than with traditional radiotherapy, often lasting only a few minutes. This efficiency reduces time spent in the clinic and allows for a quicker return to daily activities.
• Comfort: The system features a wide bore and operates very quietly. This design helps alleviate patient anxiety and claustrophobia, creating a more relaxed and less stressful treatment environment.
• Safety: Integrated imaging before each session allows for real-time verification of the tumor’s location. This continuous monitoring ensures optimal treatment accuracy and safety by adjusting for any subtle positional changes.

Are there any side effects of using the Halcyon Radiotherapy System?

While the Halcyon system’s precision significantly reduces side effects compared to conventional radiation therapy, they are not completely eliminated. Side effects vary depending on the treated area and may include fatigue or skin reactions like redness. However, these effects are typically mild, temporary, and manageable. Your doctor will discuss all potential side effects with you and explain how to manage them, ensuring you feel supported throughout the process.

What should be considered after the application?

Following your Halcyon Radiotherapy Treatment, it is crucial to follow your doctor’s instructions carefully. Resting well and maintaining a balanced, nutritious diet are essential to help your body recover.
