Image resolution

II INTRODUCTION The purpose of this lab was to demonstrate and observe the effect a large focal spot and a small focal spot will have on the resolution of the image. Chapter 3 of Practical Radiographic Imaging states that resolution is “the ability to distinguish two adjacent details as being separate and distinct from each other” (Carrol, 2007, p. 48). This definition of resolution helps to explain what will be looking for to retrieve the data for this lab. As stated in Chapter 16 of Practical Radiographic Imaging, the focal spot is defined as “the area on the x-ray tube anode which x-rays are emitted from, as seen from the viewpoint of the film” and this area can be determined by “the width of the beam of electrons striking the anode and by the bevel or angle of the surface of the anode where the electrons impact” (Carrol, 2007, p. 239). The goal of this lab is to prove that the focal spot size and the resolution are indirectly proportional to each other. This means that it should be expected that if the focal spot size decreases than the resolution increases and vice versa. To determine the data in this experiment a densitometer was used to test the resolution with the large and small focal spot sizes.…

Screen Resolutions: What You Should Know Resolution refers to the number of pixels on an image. A pixel is a tiny illumination that makes up an image. A good example is when you use Microsoft Paint with Microsoft Windows. Zoom in a little, click on the pencil and make a single dot. That could be considered a pixel. Many pixels on the screen may make up an image that you are able to recognise. http://i.imgur.com/x3hC4SA.jpg If you were to watch a video on your PC and you were able to zoom the…

Photography is one of the few fields that is actually able to capture the combination of the spiritual world, the art world and nature herself, an amalgamation that will certainly leave u breathless. What better device can you use to capture such moments than the DLSR camera. A SLR camera is different compared to other cameras because SLR camera allows the photographer to see the real whole image before hands. Most ordinary cameras usually have flaws in their viewfinder meaning they can't really…

produced the first pinhole camera after observing how light travelled through a window shutter. He realized that smaller holes would create sharper images. He is also credited with inventing the first camera obscura. Camera obscura uses a pinhole or lens to project an image of the actual scene upside down onto a viewing surface. Camera obscura lead into the development of the first photographic camera. Pinhole cameras like the Camera…

Fine art photography is photography created for aesthetic reasons. It can be used to express beauty. This type of photography can overlap with commercial, fashion, nature, black and white and portrait photography. It can also overlap with photojournalism. 2. What is stock photography? How is traditional stock photography different from micro-stock photography? Stock photography is photos that can be licensed for a certain use. Traditional stock photography is taken by professionals in a studio.…

Through this wet collodion procedure, Archer was able to overcome the flaws in the Calotype process. In this procedure, the light-sensitive material silver halide was applied to the surface of glass plates, making the resolution much higher. Although, it was a tricky process that took a lot of effort and quickness, as collodion is a sticky material and substantiates in the air. Nevertheless, the effort was way too high since collodion is sticky material that substantiates in the air.…

The contract explains what is expected of the students when there is a conflict between them and another student. There are three steps the students take when finding a resolution to the conflict. The first step is stop (calm down), the second step is slow down (agree to solve the problem), and the third step is go (problem solve). The stop light in the classroom is a visual reminder. . I think it is important for students to know at the beginning of the school year how conflicts will be…

EDMONTON - Lawyers have brokered a tentative deal to settle part of a class-action lawsuit filed over an E. coli outbreak and the largest meat recall in Canadian history. The lawsuit is against XL Foods Inc., which operated a meat-packing plant in southern Alberta during the tainted beef recall in 2012. Rick Mallett, a lawyer for the Edmonton law firm behind the class action, said the settlement is to cover refunds to consumers for products that were recalled. He said the proposed $1-million…

Given the visceral nature of both participants differences in the conflict, it is unlikely that a resolution technique such as avoiding or accommodating would be successful (Zia, 2013). Avoidance of the issue would likely have cause the ill feelings to fester for longer and resulted in a poorer outcome in the end. Furthermore, as both parties had valid points of contention, it is doubtful that either would have been able to accommodate the others viewpoint(Zia, 2013). Yet, there are other…

The problem in need of resolution is our opposing opinions concerning my summer plans, so I can stay in Hawaii and my parents can also spend time with me. My “I Message” to my parents would be that I feel frustrated when we cannot reach a decision we can both be satisfied with because I think we both want to secure our plans for the summer. I wish we could weigh the costs of both sides of our positions so we can come to a mutual…
