ALPHA
It is when only muscle and fat are imaged.
Soft Tissue Radiography
_____ ________ of breast cancer leads to more effective treatment and fewer deaths.
Early detection
The x-ray beam intensity near the cathode side of the x-ray tube is significantly higher than that on the anode side due to the heel effect.
Heel Effect
This is one important consideration in the overall efficacy of mammography.
Patient radiation dose
These are used routinely to reduce scatter radiation and improve image contrast while maintaining spatial resolution.
Grids
The second leading cause of death from cancer in women.
Breast Cancer
For symptomatic or high-risk patients, often requiring more views.
Diagnostic Mammography
The radiographic examination of the breast.
Mammography
It detects cancer in asymptomatic women using two views.
Screening Mammography
Most cases of breast cancer occur in the _________________ of the breast.
Upper Outer Quadrant
Spatial resolution and contrast resolution were much improved because of this.
Edge Enhancement.
These measure x-ray intensity and x-ray quality at the image receptor.
Phototimers or AEC devices
This set standards for image quality, patient radiation dose, personnel qualifications, and examination procedures.
Mammography Quality Standards Act (MQSA)
GdOS stands for?
Gadolinium Oxysulfide
This allows for lesser OID for better spatial resolution, uniform thickness of breast, and lower patient dose.
Compression
This rovides 3D imaging by taking multiple images at different angles while keeping the breast still.
Digital Mammographic Tomosynthesis (DMT)
The two types of filtration.
Added and Inherent
Breast tissue consists of these tissues.
Fibrous, Glandular, Adipose
Screen-film mammography uses what materials to enhance image quality?
Rare Earth Screen
The three main target materials
Tungsten, Molybdenum, Rhodium
In the 1960s, Wolf and Ruzicka showed that __________________ was superior to direct film exposure at a much lower patient radiation dose.
Xeromammography
Lower kVp improves visibility but requires _______ ____, increasing radiation exposure.
Higher mAs
The year x-ray mammography became clinically acceptable using molybdenum target.
1966
A principle to achieve the small effective focal spot.
Line Focus Principle
Large focal spot size is ____ mm.
0.3
