Description

Technical Field

[0001] This disclosure relates to the field of X-ray tubes, and more specifically, to a half-value layer measurement device for an X-ray tube assembly. Background Technology

[0002] X-ray tube assemblies are core components of X-ray machines, medical computed tomography (CT) scanners, and other similar equipment, primarily functioning to provide an X-ray source. The half-value layer refers to the thickness of the material required for X-ray intensity to attenuate to half its initial value; this is often represented by the thickness of an aluminum sheet. The half-value layer is a measurement required by relevant national standards and is tested according to regulations, representing the penetrating power of X-rays. In practice, aluminum sheets of varying thicknesses are often used for measurement; the half-value layer is obtained when the measured radiation is exactly half. Generally, different products require different testing equipment, and designing new testing equipment is necessary when launching new products, making the entire process quite complex.

[0023] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following embodiments are provided to further illustrate this disclosure in detail. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit this disclosure.

[0024] In one exemplary embodiment, see Figure 1This paper illustrates a half-value layer measurement device for X-ray tube assemblies, used to measure the half-value layer of an X-ray tube assembly. The device includes a measuring base 4 connected to the X-ray exit window of the X-ray tube assembly 6. The measuring base 4 allows the device to be fixed to X-ray tube assemblies 6 of different models and to introduce X-rays into the measuring device. The X-ray exit direction is shown as axis A in the figure. A measuring plate 5 is positioned in the X-ray exit path, installed within the measuring base 4, and positioned along the X-ray exit path to block X-rays. The device also includes a support column 3, installed at the end of the measuring base 4 away from the X-ray tube assembly 6. The support column 3 has an inner cavity extending along the X-ray radiation path to a dose detector 2. The dose detector 2 is installed at the end of the support column 3 away from the measuring base 4 and is used to detect the X-ray radiation dose. In practical use, the X-rays emitted from the X-ray tube assembly 6 pass through the measuring plate 5 in the measuring seat 4 and then reach the dose detector 2 through the inner cavity of the support column 3. When the X-ray radiation detected by the dose detector 2 is half of the initial value, the thickness of the measuring plate 5 is the measured value of the half-value layer.

[0025] In one exemplary embodiment, see further. Figure 1 To make the measurement more portable, multiple measuring pieces 5 of different thicknesses are used to form a measuring piece group. For example, measuring pieces with thicknesses of 10mm, 5mm, 2mm and 1mm are used, with multiple measuring pieces of at least 1mm thickness. In this way, by stacking these measuring pieces 5 in different combinations, measuring pieces with different total thicknesses can be obtained.

[0026] In one exemplary example, see continue to see Figure 1 It also includes a top cap 1, installed on the end of the support column 3 away from the X-ray tube assembly 6, made of radiation-shielding material, and located in the X-ray radiation path to prevent X-ray radiation leakage. Furthermore, for radiation protection purposes, the measuring base 4 and the support column 3 are both made of radiation-shielding material.

[0027] In one exemplary embodiment, multiple slots (not shown) are provided in the measuring base 4. Each slot has a different height and corresponds to measuring pieces 5 of different thicknesses. For example, it may contain 1-2 slots for inserting 10mm thick measuring pieces 5, 1-2 slots for inserting 5mm thick measuring pieces 5, 1-2 slots for inserting 2mm thick measuring pieces 5, and 2-5 slots for inserting 1mm thick measuring pieces 5. By inserting the corresponding measuring pieces 5 into different slots, different thicknesses can be obtained. To further automate the detection, each slot is equipped with a sensor. When a measuring piece 5 is inserted into a slot, the sensor transmits a signal to the calculation unit. The calculation unit obtains which slots contain measuring pieces 5, and can easily calculate the total thickness of the inserted measuring pieces, thereby automatically determining the half-value layer and displaying it using a display device.

[0028] In one exemplary embodiment, see further. Figure 1 The measurement method involves first testing the dose without obstruction (i.e., without the measuring strip 5 filter), and then testing the dose with a measuring strip 5 of a certain thickness. The ratio of the two dose values ​​is checked to see if it is less than or equal to 2. If the ratio is less than or equal to 2, a measurement result is obtained. After obtaining the X-ray tube assembly, the measuring holder 4 is installed on the window of the X-ray tube assembly 6. Combinations of measuring strips 5 of different thicknesses are added. X-rays pass through the central hole of the measuring strip 5 and the support column 3, reaching the dose detector 2, where they are blocked by the top cap 1. If the dose is attenuated by half, then the thickness of the measuring strip 5 this time is half the thickness of the X-ray tube assembly 6.
