The annual North American Radiology Annual Conference (RSNA) will once again be held as scheduled in Chicago, USA. 2023 is the 109th edition of the exhibition, and the theme of this conference is "Tomorrow's Radiology Today".
The Radiological Society of North America (RSNA) is a regional radiology academic group jointly established by the United States and Canada. It was founded in 1915 and is currently in its 104th session. It was originally called the Western Roentgen Society and was renamed RSNA in 1919.
RSNA is an internationally established society with a large number of members, high scientific level, and active academic activities. Its members are mainly located in the United States and Canada, and are divided into members, associate members, and honorary members. International members are distributed in multiple countries and regions in Europe, Asia, and Oceania, and are divided into members and honorary members. The Radiological Society of North America (RSNA) attracts approximately 55000 attendees to Chicago each year, where exhibitors can meet potential customers and stay up-to-date with the latest products and services at the exhibition.
Langfang Yushuang Instrument Equipment Co., Ltd. will bring our company's products including CT dose detection module, MRI detection module, DSA performance testing module, Gamma Knife detection spherical module, CRDR performance testing module, etc. to the exhibition.
CT dose detection phantom
The contribution of CT dose to medical radiation dose also reaches about 50%. Quality control should be maintained as a daily work for a long time. Each PMMA board has a central hole for placing blank inserts (standard) for automatic exposure control detection. The dose detection uses a hollow tube with a pen type ionization chamber (standard), and each part has 4 probe holes on the circumference. The probe holes are divided at a 90 ° angle and are 1 cm away from the edge. The child's head mold (center mold) has a probe hole at its center. The inner diameter of the probe hole is 1.31 cm. Each section includes 5 acrylic rods used to block all probe holes of the mold. The kit includes a sturdy instrument box for storing and carrying all three molds, with wheels and handles. The CT value module is used to check the CT machine's ability to distinguish substances of different densities. To check the linearity of the CT value scale, air is commonly used Organic glass material. Due to the fact that the X-ray beam energy spectrum varies with KVp and hard filtering, the image reconstruction algorithm also has an impact on the CT value results, resulting in significant errors in the CT value detection results of the aforementioned materials.
MRI detection phantom
Test cube: Use both cylindrical and spherical models. The test cube is made of polycarbonate plastic, with a thickness of 6mm and an outer diameter of 10cm. The test cube contains a layer thickness inclined surface, a photosensitive measuring bottle, a high-resolution test plate, and a low contrast flat plate.
--The high-resolution track gauge of the block is cut into 2mm thick acrylic plates supported by the internal channels of the test cube. Compared with basic MRI imaging, the principles of advanced imaging techniques are different from each other, and their ultimate information reflection is not simply limited to two-dimensional images. At the same time, a large number of image processing and data analysis techniques will be applied to advanced magnetic resonance imaging. However, the basic magnetic resonance imaging of early baseline images clearly no longer meets the requirements of advanced imaging techniques High resolution testing is accomplished by applying a testing template consisting of a series of rectangular slots, with specifications ranging from 1 to 11 line pairs per centimeter (resolution of 5mm to 0.45mm). The length of the test slot per centimeter is 1.25cm for lines 1 to 4, and 0.9cm for lines 5 to 11. Magnetic resonance quality control is one of the important imaging techniques and a significant research direction in the field of imaging technology.
Gamma Knife Testing Spherical Model
The Gamma Knife spherical detection phantom can measure dosimetric parameters such as output dose, linearity, repeatability, transmission dose, dose field distribution (such as equal dose curve, off-axis ratio, and half width of radiation field), focal ratio, and actual output dose of the treatment plan for the head gamma knife, body gamma knife, head X-knife, and body X-knife focal points.
The spherical detection module of the head gamma knife can simulate the dynamic detection process and facilitate the detection of the relevant dosimetric performance of the gamma knife in actual use. This module can be inserted into various thickness inserts used in ionization chambers, thermoluminescence films, and semiconductor detectors. Different specifications of inserts can meet the needs of different dose measurement methods during use. The clinical efficacy after Gamma Knife is a concentrated reflection of safety and effectiveness. Due to its late onset of efficacy and side effects, long-term follow-up and systematic summary are good basis for improving the quality of Gamma Knife.
The organic glass spherical mold with a diameter of Φ 160mm is one of the dosimetric performance testing devices used in gamma knife equipment. A 10mm thick insertion plate can be inserted into its center, and different insertion plates can be inserted into ionization chambers, pyroelectric chips, and semiconductors respectively.
At that time, our business personnel and technical engineers will be waiting for your arrival at the exhibition site. We welcome everyone to visit our booth for communication and guidance.
Exhibition time: November 25-29, 2023 (conference time: November 25-30)
Venue: McCormick Place, Chicago, IL, the USA
