Microwave ablation (MWA) is a minimally medical procedure used treat tumors by microwave energy. This technique utilizes microwave radiation to generate controlled heat in targeted tissues, to death while sparing healthy tissue. MWA is commonly employed in treating various cancers particularly in liver, kidney, and bone tumors.

Key component of a Microwave Ablation System:

1.Microwave Generator: Produces microwave energy specific frequencies (usually around900 MHz to 2.45 GHz which is delivered to the tissue.

2. Ablation Antenna: A thin, flexible probe that transmitsaves into the target tissue. The antenna can come in various configurations—ulated or uninsulated—and can single- or multi-pronged.

3. Imaging Guidance: such as ultrasound, CT, or MRI may be used to precisely locate the tumor and guide the placement of the ablation antenna.

4. Cooling System: Protect surrounding tissues from overheating.

In a microwave ablation system, to prevent the microwave tube (typically used for heating tissues or targeting areas) from overheating the non-target regions during the process, it is common to cool the areas outside the probe.

Combining CG series ultrasonic flow sensors with the cooling system in microwave ablation devices has enabled precise measurement of cooling liquid, contributing to real-time temperature monitoring and accurate temperature control.

This can help ensure that the ablation probe temperature remains within the set range during the continuous operation of the microwave ablation device.

1. Monitoring Cooling Flow

By continuously measuring flow rate variations, the ultrasonic flow sensor provides real-time data that enables the system to adjust cooling flow rates automatically.

2. Preventing Overheating in Unwanted Areas

By detecting abnormal flow alterations, the sensor prompts the control system to modify cooling flow rates or issue alerts, preventing damage to healthy tissues and ensuring patient safety.

The key benefits of integrating CG series ultrasonic flow sensors into microwave ablation devices include,

1. Precision and Accuracy

The CG Series boasts a high precision of ±1% and minimal error rates, helping to minimize the risk of damage to surrounding healthy tissues.

2. No-invasive Measurement, Enhanced Patient Safety

By eliminating the necessity for direct contact with the fluid, the CG series clamp-on ultrasonic flow sensor reduces the risk of cooling liquid contamination.

3. Measure Low Flow Rate

CG series flow sensors can measure meager flow rates as low as 10ml/min and can detect small changes in flow. This is particularly beneficial in microwave ablation systems where small flow variations can have a significant impact on the patient treatment process.

4. Clamp-on Design for Seamless Integration

Designed for effortless integration into existing microwave ablation devices, the Clamp-On Ultrasonic Flow Sensor can help minimize downtime and operational disruptions.

5. Customization

XYTEK engineering team can tailor designs to meet microwave ablation system-specific requirements, including alterations in sensor size, shape, color, output, tubing, and more.
