What medical radiation therapy devices use rubber seals?
Rubber seals may be used in the following medical radiation therapy devices:
Medical linear accelerators
Device shell connection
In order to ensure that the electronic components and radiation sources inside the device are not affected by external dust, moisture, etc., rubber seals may be used to seal the splicing of the enclosure to protect against water, dust, and electromagnetic shielding.
Treatment of the head part
The head is a critical part of the radiation beam that generates and controls it, and some of the moving parts and optics may require rubber seals for stability and accuracy. For example, rubber seals can be used at the rotating joint of the treatment head, the sliding part of the collimator, etc., to reduce friction, prevent dust from entering, and provide some shock absorption.
Cooling system
Medical linear accelerators generate a lot of heat when they work, and a cooling system is required to maintain the normal operating temperature of the equipment. Rubber seals may be used to prevent coolant leakage at locations such as the pipe connection of the cooling system, the junction of the radiator and the body of the equipment, etc.
Gamma knife
Helmet part
The helmet of the Gamma Knife is a key component that precisely focuses the radiation beam on the patient's lesion site. In the connection between the helmet and the body of the device, rubber seals may be used to ensure the tightness of the helmet and prevent radiation leakage. At the same time, the rubber seals can also act as shock absorbers, reducing the vibration of the patient's head when the equipment is running.
Mechanical movement part
There will usually be some mechanical movement mechanism between the treatment table and the body of the device to adjust the position and angle of the patient. At the junction of these kinematics, rubber seals may be used to reduce friction, prevent dust from entering, and provide some cushioning and shock absorption.
Control system
The control system of the gamma knife usually includes parts such as electronic components and displays, which need to be well-sealed and protected. Rubber seals may be used at locations such as the connection of the enclosure of the control system, the junction of the display and the panel, etc., to prevent the ingress of dust and moisture, which can affect the normal operation of the equipment.
After-loading treatment machine
Therapeutic source channel
Afterload treatment machines are treated by delivering a radioactive source into the patient's body, and the treatment source channel needs to be well sealed to prevent radiation leakage. At the inlet and outlet of the source of the therapy channel, rubber seals may be used to ensure tightness.
Mechanical movement part
The treatment head and table of a rear-loading treatment machine usually have some mechanical movement mechanism for adjusting the treatment position and angle. At the junction of these kinematics, rubber seals may be used to reduce friction, prevent dust from entering, and provide some cushioning and shock absorption.
Control system
The control system of the after-loading treatment machine also needs to be well sealed and protected to prevent dust and moisture from entering and affecting the normal operation of the equipment. Rubber seals may be used to provide sealing protection at locations such as the enclosure connection of the control system, and the junction of the display and the panel.
