Proton Therapy System：An Advancement in Cancer Radiotherapy

Learn More About Proton Therapy System

Proton therapy is an advancement in cancer radiotherapy. It delivers a more precise dose to tumors than photon radiotherapy and limits the dose that reaches healthy tissues.

If you wish to buy a proton therapy system in your facility, this guide will help you make the best choice. You'll also learn about the parts and types of proton therapy systems and what to look for when buying a Proton therapy system. Let's dive right in.

What is a Proton Therapy System?

Proton therapy or proton beam therapy system is the medical equipment used to deliver radiant precision treatment that uses heavy particles and protons to irradiate cancer cells. The physical characteristics of the proton beams are such that they allow the dose to be released with extreme precision, thus avoiding the involvement of the surrounding healthy tissues.

Proton beam therapy has fewer side effects and improves the quality of life of cancer patients. As a result, proton therapy enables the treatment of complex and resistant tumors and is especially beneficial in pediatric cancers.

Proton therapy has been used in clinical treatment for more than 40 years. Compared with traditional radiotherapy equipment that sells for several million US dollars, proton equipment is more than $20,000,000. At the same time, because the proton equipment is up to ten meters high, it generally needs 2-3 stories high. The floor space is even more impressive, generally more than 5,000 square meters. The annual maintenance cost of the equipment requires tens of millions. From design to completion and commissioning, it takes a few years to as many as ten years. Therefore, the construction of the proton therapy center can be described as consumable and labor-intensive.

A proton therapy system is also known by other names like proton therapy machine, proton beam machine, proton system, or proton therapy device.

Types of Proton Therapy

There are two main types of proton therapy delivery: passive scattering beam and Pencil beam scanning beam delivery.

Passive scattering beam delivery

Passive scattering is an individualized type of proton therapy. As a result, each system component is modified to fit the patient's needs. This delivery involves the technique of spreading the proton beam.

The proton beam is a few millimeters wide, therefore in clinical cases. Thus there is a need to spread the beam to a uniform area to allow for equal and precise dose distribution in depth. There are two scattering systems; single and double. The single-scattering systems spread the proton beam in a Gaussian manner and are meant for small-sized fields. On the other hand, the double scattering systems are for bigger fields and allow minimal energy loss.  

The compensator shapes the beam to achieve a lateral dose distribution. There can be variations in the number of proximal peaks, thereby varying the uniformity in depth. Passive scattering beam delivery is most preferred in treating complex tumors around the spinal cord, head, neck, and oral cavities.

Pencil beam scanning beam delivery

Pencil beam scanning (PBS) has greater precision and efficiency than passive scattering beam delivery. PBS proton therapy makes it possible to control the beam's depth and position, thereby offering a precise three-dimensional delivery of proton on the tumor. Shaping the proton beam does not require compensators. PBS delivers multiple beams in 3D. Thus, the shape of the beam conforms with the target tumor shape to allow for equal dose distribution to each layer.

Pencil beam proton therapy is useful in treating tumors in the brain, lung, duodenum, prostate, and eyes, including pediatric cancers.

What is the difference between proton therapy and radiation therapy?

The main purpose of oncology is to cure cancer without damaging healthy tissues. Proton Therapy has come very close to this milestone. Radiation therapy is one of the cheapest methods of treating malignant tumors with a relatively high degree of positive results.

Proton Therapy is a type of high precision radiotherapy, mainly due to the nature of the protons themselves but also to the type of distribution of the dose of protons between the tissues. The results of this type of therapy are the low probability of proximal healthy tissues being damaged, the low risk of complications, and a high probability of rapid recovery after treatment.

During traditional radiation therapy, a beam of photons transfers high dose radiation to the tumor and tissues next to the tumor. But with Proton Therapy, a proton beam transfers a high dose only to the area of the tumor. As a result, Proton therapy has a limited impact on healthy tissues proximal to the tumor.

Parts of a typical Proton Therapy System

The major parts of a proton therapy system include the cyclotron, gantry, irradiation chambers, electromagnets, beam transport system, and treatment room. These parts function to ensure that the proton beams are focused primarily on the tumor being treated and not the healthy cells.

Proton Therapy System uses/applications

Proton beam therapy is applied in cancer treatment and other non-cancerous tumors in pediatric and adult patients. It is also used for patients who experience certain side effects of chemotherapy.

What to look for when buying a Proton Therapy System?

Budget

Budget is an important factor to consider when investing in a proton therapy system. It is something that should always be taken into account when buying a product. This is due to the price that each brand may have and the value for money that the product may have.

That is why the first thing you should do is find out how much the product costs, determine if it is within your budget or not and if its features are satisfactory.

Brands

When you've finalized your budget, the next thing to do is invest in only reputable brands. Among the major manufacturers of proton therapy systems in the world are Varian Technologies, Sumitomo Heavy Industries, Mevion, ProNova, Hitachi, IBA, Mitsubishi Electric, ProTom International, and Optimus.

In addition, ensure the proton therapy system has the necessary certifications like CE, ISO, and FDA. This is to confirm that the product was manufactured under international standards.

Functionality and features

There are different types of proton therapy systems on the market, so you should pay attention to the features. Look out for compact systems with a flexible layout that you can adjust to fit the purpose of the therapy.

Also, proton therapy systems that deliver beams with a high dose rate are most suitable as they reduce the treatment period. In addition, the system should allow for proper positioning of your patient. 

There are also proton systems with single and double room configurations. Ensure you access the features of the proton system to satisfy the purpose of the therapy before purchasing.

Warranty

Investing in medical equipment like a proton therapy system requires financial security. Therefore, it is essential to review the vendor's warranty should there be any malfunction during use.

Also, there should be provision for the installation and ongoing maintenance of the proton therapy system.

Vendors like Medwish.com provide a warranty that covers potential losses that may occur during shipping.

Payment options

There should be a variety of payment methods for you when purchasing a proton therapy system, from credit cards to PayPal, and MoneyGram among others. Also, consider the financing options provided to ensure a smooth transaction.

Proton therapy system vendors like Medwish.com offer both product financing and hospital project financing. As a result, you can make purchases that suit your budget.
