The development of radiotherapy equipment technology has led to clinical advancement. Major equipment manufacturers include Varian Medical Systems, Medical Medical, and ACCURAY. The latest technologies and progress of these three radiotherapy systems will be introduced below.
Varian's new technology progress
In the Varian Radiation Therapy Solution, the RapidPlan Automated Therapy Design System was introduced. RapidPlan is an automated design tool based on empirical knowledge, using standard treatment plan design templates, and its database is derived from top-level oncology centers. The system's self-performing “learning†and training can improve the quality and consistency of program design, significantly reduce planning time, standardize the treatment planning process, and automatically optimize and provide multiple treatment options. At present, domestic Beijing Cancer Hospital and Fudan Cancer Hospital have carried out clinical tests.

Varian's new True Beam and EDGE radiosurgery integrated solution is a surgical system that enables non-invasive screen "surgery" without the need for third-party products. Both True Beam and EDGE can be used for radiation therapy in all parts of the body. Its advantages are reflected in the rapid sharpening of the edge dose drop, the sub-millimeter clinical accuracy and advanced imaging technology, and equipped with robot bed placement technology and real-time tumor tracking technology.

Based on a deep understanding and thinking of the development trend of radiosurgery, Varian Medical System has launched a new targeted radiosurgery system for the market. It is a comprehensive integration and innovation of current clinical radiosurgery technology, and is the pinnacle of radiosurgery system. The Targeted Positioning System integrates Calypso radiosurgery navigation system, robotic kV-level target tracking imaging technology, 3D/4D CBCT technology, large-scale high-speed dynamic EPID imaging technology and respiratory gating technology to provide complete clinical requirements. Targeted four-dimensional image guidance and target tracking in treatment.

Specially equipped with a cone-shaped light-limiting tube for SRS treatment of small lesions, high-resolution MLC system (2.5mm blade width) for SRS and SBRT, fully automatic control of six-degree-of-freedom treatment bed for precise positioning. The intelligent control system (Maestro) automatically implements accurate beam engraving projections around the lesion under the guidance of its sharp viewing angle, while its physically steep dose drop characteristics give better protection to surrounding normal tissue. Ultra-high dose rate (1400~2400MU/min) and ultra-fast control system response speed (10ms).
Through the original RapidArc volume-modulated illumination technology, the scalpel-like high-dose high-energy beam instantly delivers tumor-damaging ablation. Under the precise guidance of the kV image target real-time tracking or Calypso radiosurgery navigation system, the beam is dynamically manipulated for respiratory-gated spot-directed illumination, or the multi-leaf collimator is used to follow the tumor to provide tracking illumination to achieve accurate target Strike.
About RapidArc
Calypso Radiation Surgery Navigation System - a tool for targeted tracking of motor tumors: GPS electromagnetic beacons (3) that are specifically recognized by individuals are directly implanted into the tumor, and tumor movement is continuously monitored during the treatment. When the amplitude of motion exceeds the preset error limit, the beam can be automatically cut off to ensure the safety of treatment. The use of electromagnetic technology rather than ray tracing avoids secondary damage to the patient. GPS beacons are CT/MR compatible and do not affect CT analog positioning and MR scanning after implantation. The PortalDosimetry airborne quality control system can more effectively escort complex treatment technologies. With the support of the onboard system, QA work can be completed within 5 minutes, making complex treatment techniques more accessible to everyday clinical practice.
Vitamins are a type of trace organic substances that humans and animals must obtain from food in order to maintain normal physiological functions. In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.
