Topic 5. X-Ray applications Flashcards
This X-ray forms real-time x-ray used for imaging motions within the body, it uses fluorescent materials to convert x-rays into visible light on phosphor screen. Individual images are of much lower quality than single image receptors
Fluoroscopy
This medical imaging device is used flexibly in various ORs
and Connects X-ray source to X-ray detector
C-ARM
This Medical imaging device connects X-ray source to X-ray detector and is used for: Spine, orthopedic (bones), trauma-related surgeries
O-ARM
This device is used to visualize within BLOOD VESSELS and ORGANS (arteries, veins, heart chambers).
It also Injects a radio-opaque contrast agent into the blood vessel
Angiography
This device uses LOW-DOSE x-ray systems to see inside the BREASTS and Aides in early detections of breast diseases
Uses:
Low tube potentials (25kV to 35 kV)
An Anode target
K-edge filters
Mammography
The Anode target in Mammography devices are made of
molybdenum or rhodium
K-edge filters in mammography devices are made of
made from molybdenum, rhodium, and silver
List the three major advances in mammography
Digital mammography
Computer-aided detection
Breast tomosynthesis
An advanced form of breast imaging, where Images from different angles are captured and reconstructed into a 3D set (similar to CT imaging).
Radiation dose higher than mammography.
Improved breast cancer detection, fewer call-backs
is known as?
Digital breast tomosynthesis (DBT)
Digital breast tomosynthesis (DBT) may also result in
Earlier detection of breast cancer (and multiple tumors)
Greater accuracy for size, shape, and location OF TUMOR
Fewer unnecessary biopsies
Clearer images of abnormalities
This device measures bone loss and osteoporosis.
- It uses very small ionizing radiation to measures bone loss
- Diagnose osteoporosis, or, assess risk of fractures (most accurate)
- Simple, quick, noninvasive
DEXA: Dual-energy x-ray absorptiometry
This device take a 2D dental X-ray examination, captures entire mouth in a image
- Produces FLAT IMAGE of jaw structure
- The film is contained INSIDE the machine (Not in the mouth like traditional intraoral X-rays)
- Captures complete image of the side of the face
Panoramic Radiography
This device is used when REGULAR Dental/facial X-rays are NOT SUFFICIENT
- Higher radiation exposure than regular dental x-rays
- Creates 3D images (instead of 2D in panormaic radiography) of dental structures, soft tissues, nerve paths, and bones
- Images allow for PRECISE treatment planning
- X-ray beam, in the shape of a CONE, moves AROUND THE PATIENT to produce a larger number of pictures
