The c-arm machine is the common name of the c-arm, also called the c-arm X-ray machine. It belongs to the X-ray computed tomography equipment. Therefore, there will be a certain amount of radiation generated during the use process, which may be harmful to medical staff and operators. to varying degrees of harm.

What is the radiation range of the c-arm machine?

X-rays have three effects when they enter the body: 1. Passing through the body 2. Absorbed by the body 3. Scattering (X-rays excite new rays).

After the radiation emitted by the tube enters the human body, 1% passes through the human body and enters the intensifier, the remaining 80% to 90% of the radiation is absorbed by the patient, and 10% to 20% of the radiation is scattered by the body. The ray increases by a times of the original with the distance, and the intensity decays to 1/a2 times of the original.

Therefore, the farther away from the c-arm machine, the less radiation damage. The radiation range of the c-arm machine is more than 2 meters, and the radiation amount is very small at a distance of 2 meters from the c-arm machine. Therefore, the safe distance of the c-arm radiation in the operating room is more than 2 meters. Generally, it is recommended to be behind a lead screen that is two meters away. .

Is the radiation of the C-arm machine in the operating room large?

C-arm machines produced by different manufacturers have different radiation levels.

What is the radiation range of the C-arm machine? Is the C-arm machine radiation in the operating room large?

Take the integrated large-plate mobile c-arm of the model PLX119C produced by Nanjing Puai as an example. The amount of radiation leakage under the loading state is relatively small, which is about one-third of the CFDA industry standard.

PLX119C uses the high-frequency and high-voltage generator technology independently developed by Puai. In the composition ratio of the x-rays it emits, the proportion of hard rays that are less harmful to the human body is relatively high, while the proportion of soft rays that are easily absorbed by biological tissues is relatively low. .

What is the radiation range of the C-arm machine? Is the C-arm machine radiation in the operating room large?

In addition, the PLX119C model c-arm machine uses a large 30*30cm flat panel, which has a wide field of view and can present the entire lumbar spine in one exposure. For example, in surgeries that require a large field of view, such as pedicle screw fixation, the use of PLX119C can help doctors better locate the lesion point, plan the surgical plan, and avoid multiple photography due to insufficient field of view. The total amount of radiation produced by surgery.
