![]() It’s a deep relationship that we value, and we know that we can count on them for the very best. In addition, QSA supports their products with training courses that we offer at both our Edmonton and Burlington locations. They are the largest manufacturer of radiography gamma projectors and sources in the world. QSA Global has been our preferred supplier since we first opened our doors in 2004. The sources available from IR are manufactured exclusively by QSA Global. This difference is particularly beneficial when doing digital imaging–CR or DR–where an optimal picture is the primary goal. For example, an IR192+ source will almost always deliver one more wire on an image quality indicator (IQI) compared to the same curie strength in a Ir192 source. A smaller focal spot typically delivers an improved image. What form is it in Ir-192 used in medicine is in. The second benefit is specific to image quality. Ir-192 is a manmade radioactive element that is formed from nonradioactive iridium metal in a nuclear reactor. Cause specific survivals were 90, 71, and 46, respectively. Five-year actuarial survival was 52 for T1N0, 44 for T2aN0, and 8 for or T1-2 N1-3. Iridium, symbol Ir, has a Face Centered Cubic structure and Silver color. Between 19, 166 patients with T1 or T2 epidermoid carcinomas of the mobile tongue were treated by iridium 192 implantation (70 T1N0, 83 T2N0, 13 T1-2 N1-3). However, one can get both a small focal spot and a high specific activity from an Ir192+ source. Element 77 of Periodic table is Iridium with atomic number 77, atomic weight 192.217. The drawback to this is that you will have longer exposure times with the lower curie source. For instance, a 50-curie standard source will have a smaller focal spot than a 100-curie standard source. Performing radiography with a source that has a smaller focal spot has two key benefits.Ī small focal spot can be achieved with a Ir192 source by ordering a lower curie activity. Specifically, the difference between the two is the focal spot. Ir192+ is often used for more specialized jobs where optimal quality is essential. Generally, you will use premium for a high-performance vehicle. The later is a higher grade with special features used for different applications than regular gas. When you arrive at the pumps with your car you have the option of buying regular gas or premium gas. A simple analogy is to think of it as gasoline. Relative to standard Iridium (Ir192), enriched Iridium (Ir192+) is more concentrated.
