example 1
[0041] Figure 4 and Figure 5 The measurement of radiation exposure by use of a phantom is shown to help illustrate the benefit of extending the panel 3, where 1.1 indicates the front of the head and 16.3 indicates the back of the head. according to Figure 4 and Figure 5 The regimen in the throat, jaw, ears, brain and scalp (by Figure 6 Dosimeters are placed in cross-sections in sections A (throat), B (jaw), C (ear), D (brain) and E (scalp) shown in ). The exposure time is 20 minutes, after which the dose is read. Table 1 below shows the wearable according to Figure 3a Radiation exposure of users of conventional radiation protection equipment.
[0042] The X-ray device used during the measurements was a Philips Multi Diagnostic Eleva FD (Koninklijke Philips Electronics N.V). Set the patient table to a zero-degree angle and use the under-table X-ray tube position without rotation. In addition, the zoom format is 48 cm, using a field size of 30 cm × 30 cm, with a so...
example 2
[0047] Another test was performed with the same test setup as Example 1, using products according to embodiments of the present invention instead of normal radiation protection products. The extension panel 3 has the following measurements; the product has a distance f of 60 mm and an angle a of 36 degrees, see Figure 3b . Table 2 below shows that in accordance with Example 1 and Figure 4 Results when the phantom head is exposed.
[0048] Table 2 below shows the quotient between the radiation exposure of a user wearing a normal thyroid collar according to Example 2 compared to the setting according to Example 2 without any protection. The values in Table 2 are in Sections A to E (eg Figure 6 shown) in each location (as in Figure 4 and Figure 5 shown) quotient. A quotient of 1.0 and higher indicates no measured radiation reduction, while a quotient below 0 indicates a measured radiation reduction of 100%. A quotient between 0 and 1 indicates a reduction in radiati...

[0053] In another example, it is shown as Figure 3a Shown is the efficacy of a common protective collar design according to the prior art. Thyroid collars come in standard sizes. The Thyroid Collar is made of woven radiation shielding material with safety class 0.5mmPb. Physician phantoms were set up in a clinical operating room equipped with a Siemens Artis Q (Siemens Healthineers, Germany) angiography system and a Philips Multi DiagnostEleva FD (Koninklijke Philips Electronics N.V) to simulate Clinical situation during image-guided surgical intervention. The c-arm angular position is such that the physician's phantom is placed frontally (zero degrees) toward the patient's operating table, with an under-table X-ray tube position, and the imaging area of the patient's phantom is to the left in front of the physician's phantom. The patient phantom was placed on a table 80 cm above the floor with a height of 21 cm in the central beam. Zoom format is 48, SID is 125cm, 2 fr...
