QAQC In Medical radiography Flashcards
Factors affecting image quality
Patient Image Receptor Technique Variables Interpreter View conditions Motion Geometric variable Processing conditions
Fidelity with which the anatomic structures being examined are imaged on the film
Radiographic image quality
High kvp =
High density
Low contrast
Low mAs =
High density
No change in contrast
Physician that specializing in obtaining and interpreting medical image obtained by using xrays
Radiologist
Can enhance or degrade the subtle details of radiographs
Viewing conditions
Can be controlled by keeping the examination time short and ask the patient to remain still
Voluntary motion
Impacted by film processing parameters such as darkroom conditions, tempt of solution and developing time
Radiographic quality
Oraganized effort of a facility to ensure high standard quality of products
Quality assurance
Quality Assurance is consists of
Quality Administration
Quality Control
Managerial functions initiated to qc measures
Quad procedures
Requirements of QAQC programs
Combined efforts of rad staff
Institutionalized
Roles and responsibility of each member
Onjectives of QAQC
Minimized patient exposure Cost reduction Better inage quality Identify main errors Basis for support claims
Concerns of quality programs
Minimizing patient’s radiation exposure
Maximizing film quality
Reducing film exposures
Optimizing use of staff time
Conversion of latent image to manifest image
Film processing
