22. X-RAY APPLICATIONS: FLUOROSCOPY Flashcards
1
Q
- What is Fluoroscopy?
A
- it is a form of real time X-ray imaging
- it is a dynamic technique
2
Q
- What is a Radiograph?
A
- it a presentation of the anatomy at a particular
moment in time
3
Q
- What is Fluoroscopy used for?
A
- it is used for imaging motions within the body
- it is used for many interval procedures
- these procedures are done under X-Ray Guidance
4
Q
- What does Fluoroscopy make use of?
A
- it uses fluorescent materials
- these convert the X-Rays into visible light
- they do this onto a Phosphor screen
5
Q
- What kind of quality are the individual Fluoroscopy images?
A
- they are of a much lower quality
- this can be achieved with single image receptors in
terms of:- spatial resolution
- noise
- contrast
6
Q
- Label this diagram.
A
- X-Ray Source
- X-rays
- Bed
- Person
- Fluorescent Screen
- Digital Detector
- TV Camera
- TV Monitor
7
Q
- What happens at the X-Ray Source?
A
- the X-Ray Beam is produced
8
Q
- Which 2 kinds of detectors can we have in Fluoroscopy?
A
INDIRECT DIGITAL DETECTOR:
- such as the image intensifier
DIRECT DIGITAL DETECTOR:
- such as the Flat Panel
9
Q
- What is the function of the TV Monitor?
A
- this is where the final images are displayed in real time
10
Q
- Why is Fluoroscopy important?
A
- it has replaced many surgical procedures
- the X-Ray guidance of this technique allows us to insert
medical equipment into the human body - this takes away the need to do an open surgery
11
Q
- What does these images represent?
A
- a mobile C-arm
- this machine can be rotated and positioned to look at
various aspects of the patient - this machine can be transferred to various rooms
within the hospital
12
Q
- What is a mobile C-arm?
A
- it is a medical imaging device
- it is based on X-Ray technology
13
Q
- In which settings is the mobile C-arm device used?
A
- it is used flexibly in various ORs within a clinic
14
Q
- What gives the C-arm its name?
A
- the C-shaped arm
- this arm connects the X-Ray source to the X-Ray
detector
15
Q
- What is this image showing?
A
- the mobile O-arm
