Collimation Intensifying Screen speed film speed
Factors which we do not adjust, but can affect density Processor Pathology Patient size (maybe we can compress?)
Contrast Compensation Factors KVP MAS Collimation OID Patient (Do we adjust the patient?)
Factors which we do not adjust which effect Contrast Processor Filtration? Film
Factors which effect Detail SID OID FS SCREEN FILM MOTION
Factor we do not adjust Film/screen contact

Analyzing the Image Density. Density Overall blackening of the image.
Quality Control. HIGH QUALITY FILMS REPRODUCES ANATOMICAL IMAGE EXACTLY FILM HAS: CORRECT TECHNICAL FACTORS NO MOTION NO ARTIFACTS PROCESSED CORRECTLY.
Image Production and Evaluation NOTE: QA AND QC ARE USED INTERCHANGABLY IN APPLETON AND LANGE.
1 RT 123 WK 3 Lecture #3 PRINCIPLES OF TECHNIQUE AND EXPOSURE.
Radiographic Quality Visibility and Sharpness By Prof. Stelmark.
TECHNIQUE EVERYTHING YOU WANTED TO KNOW BUT WERE AFRAID TO ASK!!!!
Components of Radiographic Image Quality Radiologic Technology 244 created: Fall 2005 Rev
RAD 254 Chapter 15 Radiographic Technique 4 primary exposure factors are: kVp, mA, time, distance.
Chapter 11 Prime Factors. Prime factors: affect x-ray emission; under the control of the radiographer. –Miliamperage-second (mAs) –Kilovoltage (kVp) –Distance.
IMAGE QUALITY REVIEW Dr Mohamed El Safwany, MD. Intended learning outcome The student should learn at the end of this lecture radiological image quality.
RAD 354 Chap. 13 Radiographic Technique Four PRIMARY exposure factors: – kVp – mA – Time – distance.
IMAGE QUALITY REVIEW RT What affects DENSITY on the radiographic image?
Image Evaluation Guidelines for Image Analysis Chapter 1.
1 Kilovolt Peak (kVp) kVp determine the quality of the beam. X-ray penetration is governed by the kVp setting. kVp controls the contrast of the radiographic.
Technical Aspects: the machine the image LeeAnn Pack DVM.
Exposure Factors or Prime Factors 1. PRIME FACTORS What is “technique” ? How does it affect the “image” 2.
Technical Artifacts and Errors Chapter 11. Artifacts Anything that decreases the quality of the radiograph resulting in difficult evaluation and interpretation.
1 RTA 2011 WK 5 FINAL Tube Exposure Factors Math Technique Contrast and Density.
Radiographic Quality Chapter 5. Radiographic quality Refers to how easily details can be perceived on a radiograph. Need to obtain as much diagnostic.
Image Quality Radiographic Resolution. Demelza Green Jan 2004 Technologies for Imaging.
RAD 354 Chapt. 16 Image QUALITY “Finite” Radiographic quality – Noise – Resolution Spatial resolution – Contrast resoultion – Noise.
[Radiography] Technique - Exposure Factors. KVP = Energy of x-rays = higher penetrability, it moves through tissue. The energy determines the QUALITY.
Chapter 18 Radiographic Exposure Exposure Factors influence and determine the quantity and quality of the x-radiation to which the patient is exposed.
1 Components of Image Quality & Radiographic Artifacts Radiologic Technology A SPRING 2012.
Chapter 10 Exposure Mathematics. Exposure Mathematics u We have seen in Chapter Seven that there are several exposure factors that are predetermined before.
Components of Image Quality & Radiographic Artifacts Radiologic Technology A Spring 2010 Final Final.
FILM ARTIFACTS. ARTIFACTS: AN UNWANTED DENSITY ON THE FILM
1 MAMMOGRAPHY MAMMO QC – covered in week 8 Rev. Spring 2014 Equipment – Lecture #1 Bushong Ch. 23.
RADIOGRAPHIC DENSITY Sergeo Guilbaud School of Radiologic Sciences.
IMAGE QUALITY AND ARTIFACTS 1 2 WHY YOU SEE WHAT YOU SEE… The films or images have different levels of density – different shades of gray X-rays show.
RAD 354 Chapt. 11 Control of Scatter Break down into: Those that reduce pt. dose and those that are geometrical in nature and those NOT! 3 factors affecting.
Week Seven. VETT 116: Veterinary Diagnostic Imaging 1 Overview of Week 7 A technique chart provides a consistent method of choosing the proper radiograph.
RAD 254 Chapter 16 Image Quality Film factors Geometric factors Subject factors.
Topic 3 Selection of kV High kV scattered radiation is energetic. Angle of rays is same as those of primary beam and is not deflected very much. Follows.
