RTC 100--Group 5 Presentation
Topic for Group 5
What factors are used to determine the quality of a radiographic image? What makes an image good, and conversely, what do people see when they look at an image and determine that it is bad?
Discuss the geometric factors and subject factors that affect image quality. Make sure to include images and diagrams to illustrate your answers and emphasize your key points

RTC 100--Group 2 Presentation
Topic for Group 2
Describe the various components of a typical x-ray tube. Make sure you have a clearly labeled diagram of the x-ray tube. What is the function of each component? What are the differences between a stationary anode tube and a rotating anode tube? Also discuss recent innovations in x-ray tube design. What design features have been introduced, and how do these new design features improve on what existed in the older tubes?

RTC 100--Group 1 Presentation
Group 1 presented information on the X-ray Operator Console.
Take a picture of a typical x-ray operator's console. Discuss each of the dials, switches, displays, and buttons on or connected directly to the operator's console. What is the purpose of each component of the console, and how does it impact the production of x-rays and/or the appearance of the radiographic image?

RTC 100--Group 3 Presentation
The first three group presentations went off successfully on Thursday, November 6th.
All the group members did well, and I am extremely proud of the effort that was made.
Below is group three's presentation. I will be posting each presentation online in the upcoming weeks.
Group 3's topic was:
Judge for yourself how well they did.

Group 3's topic was:
Take pictures of the equipment in your energized x-ray lab. (Table, bucky tray, vertical cassette holder, grid, generator, high tension cables, tube housing, collimator, etc.) Describe the purpose of each bit of equipment in your x-ray room. Your discussion should answer the questions what does it do, or what is it used for?
Judge for yourself how well they did.

RTC 100--PowerPoint Presentation Topics Groups 7 & 8
The following topics will be presented on Thursday November 20, 2008.
Topic for Group 7
Provide details of the use of intensifying screens in Radiography. Use a diagram to discuss the details of the structure of an intensifying screen. Discuss the various screen-film combinations. Describe the handling and cleaning of intensifying screens. What is the result of poor film/screen contact? (Show an image) How is radiographic technique adjusted for variations in screen speed?
Topic for Group 8
Radiography has gone filmless. No film? Just as photography is now predominantly digital, radiography is heading in that direction as well.
Discuss the major forms of digital radiography now in use. How do they compare to traditional (film or analog) radiography? For example, how has the introduction of filmless radiography affected Radiology department expenses, workflow, and number of repeats?
Do not get caught up with details of the technology or how digital radiography works. The intent of your presentation is to introduce the class to the current trend in imaging, and the advantages and disadvantages of going digital. Crucial questions that should be answered are: is it cost effective? Does it save on patient radiation dose? Does it expand the availability of images? Are there any adjustments that have to be made by the radiographer to their technique and the way imaging devices are handled? What about workflow? Are there any improvements in patient throughput when we go from film to filmless?
