Why Choose a High-Power High-Voltage Generator for C-Arm X-Ray Machines in the Operating Room

 X-ray machines? In modern medical equipment procurement, operating room C-arm X-ray machines are indispensable important equipment in departments such as orthopedics and interventional radiology, providing doctors with efficient and accurate imaging support. However, when purchasing C-arms, the power parameter of the high-voltage generator is often overlooked, which is actually one of the key factors determining the performance of the equipment. Next, let’s understand why high-power high-voltage generators should be chosen when purchasing operating room C-arms.

C-arm X-ray machine in the operating room

The high-voltage generator is one of the core components of the operating room C-arm X-ray machine. Its main function is to provide a stable high-voltage power supply and filament heating current for the X-ray tube, thereby generating X-rays to support real-time imaging.

The power parameter of the high-voltage generator largely determines the imaging effect of the C-arm. Nowadays, C-arms with high-power high-voltage generators are generally favored by hospital purchasers. For example, the PLX C7600 series 3D flat-panel C-arm from Perlove Medical has attracted great attention in the industry since its launch. This equipment is equipped with a 25kW high-power high-voltage generator, with a maximum tube voltage of up to 120kV. Combined with high main inverter frequency technology, it outputs more abundant X-ray energy.

Advantages of choosing high-power high-voltage generators for operating room C-arm X-ray machines:

1. Improve imaging quality
   • Enhance ray intensity: High-power high-voltage generators can generate stronger X-rays, which helps increase the contrast and signal-to-noise ratio of images, making them clearer and more detailed.
   • Reduce artifacts: When providing stable high-voltage output, high-power high-voltage generators can reduce motion artifacts and other interference factors in images, improving the stability and reliability of images. This is particularly important for surgeries that require long exposure times or continuous fluoroscopy.
2. Adapt to different needs
   • Different body types and parts: C-arm X-ray machines need to penetrate different density tissues of the human body (such as bones, muscles, fat, etc.). High-power high-voltage generators can provide higher tube voltage (such as ≥120kV) and tube current (such as ≥20mA) to generate high-energy X-rays, ensuring penetration for obese patients or high-density tissues (such as lumbar spine, pelvis).
   • High-dose continuous exposure: High-power high-voltage generators are equipped with high heat capacity tubes (such as ≥800KHU) and efficient heat dissipation systems, which can withstand continuous high-intensity exposure. Orthopedic surgeries or complex interventional procedures often require multiple imaging, and high heat capacity prevents the equipment from reducing frequency or shutting down due to overheating, ensuring the continuity of the surgery.
3. Improve equipment performance
   • Stable output: High-power high-voltage generators usually adopt high-frequency inverter technology, with high inverter frequency and more stable output high voltage.
   • Extend equipment life: High-power high-voltage generators can provide more stable and powerful energy output, which helps extend the service life of key components such as the tube and reduce equipment maintenance costs.

1. High power has no direct relationship with radiation dose
   Many people think that the higher the power of the operating room C-arm X-ray machine, the greater the radiation exposure to doctors. In fact, the harm of X-rays to the human body is mainly related to scattered rays and the length of exposure time. Because high-power C-arms emit X-rays with high quality and strong penetration, they can obtain clear images while reducing the exposure time, which can actually reduce the harm of X-rays to the human body.

Medical equipment procurement decisions are related to the quality of clinical services in the next 5-10 years. Although high-power high-voltage generators increase the initial investment, the improved image quality, increased surgical efficiency, and long-term reliability guarantee will eventually translate into better patient outcomes and higher medical value. It is recommended that hospitals, within the allowable budget, give priority to the power index of the high-voltage generator and choose professional operating room C-arm X-ray machines that truly meet clinical needs.
