　　In modern medicine, linear accelerators have become an important therapeutic tool, which can produce high-energy X-rays or gamma rays to kill tumor cells. However, this device requires precise detection and adjustment of the photon beam during treatment to ensure that it can accurately illuminate the tumor site. This requires the use of a tissue-equivalent solid water phantom.

 

　　Tissue equivalent solid water phantomIt is a new type of phantom that can replace the traditional water tank for routine detection of linear accelerator photon beams. The main features of this phantom are its speed and simplicity, and each product is tested for water equivalence in an independent calibration laboratory before being put into use. This kind of testing can ensure that the performance of the phantom is consistent with real human tissue, allowing doctors to adjust the parameters of the photon beam based on the detection results of the phantom so that it can accurately illuminate the tumor site.

 

　　The main advantage of this phantom is its speed and ease. Traditional water tank phantoms require complex preparation work before use, including filling water, installing positioning devices, etc., and the water needs to be replaced regularly during use to prevent changes in water quality from affecting the test results. This phantom does not require these steps. You only need to place it in the linear accelerator and start testing immediately. The use of this phantom greatly improves the efficiency of testing, allowing doctors to obtain test results faster and thus perform treatment faster.

 

　　The phantom also has good stability. Because it is made of a special material, it is very strong and does not stick together when stacked and stored. This allows the phantom to maintain good performance in any environment without affecting the test results due to changes in temperature and humidity. This stability makes the phantom ideal for linear accelerator inspections.

 

　　Tissue-equivalent solid water phantoms are a useful tool for improving the efficiency and accuracy of linac photon beam detection, thereby improving treatment outcomes. Although its manufacturing cost is relatively high, with the development of technology, we have reason to believe that this kind of phantom will be more widely used in the future.
