326
History of Plain Film Radiography
- discovered by Wilhelm Roentgen in 1895
- named "x-rays" due to uncertain nature of rays
- led to one of the most significant advancements in medical history
- Marie Curie discovered radioactive elements
- awarded nobel prize 1901
- made without contrast enhancement
- form of electromagnetic radiation
327
X-ray Wavelength
- shorter wavelength = the higher the energy and greater penetration of dense substances
- produces ionization of atoms and molecules (loss of electrons)
- results in a gray image on the radiograph
328
Production of a radiograph, requirements:
- an x-ray beam source
- a patient
- an x-ray film or image receptor
329
X-Ray Tube
- cathode (negative) and anode (positive) enclosed in glass envelope which maintains a vacuum (heated thoriated tungsten filament in cathode assembly)
- high voltage current passes through vacuum
- electrons are driven from cathode and strike anode (decelerate and create x-rays via energy consumption)
330
Making a Radiograph
- current is beamed through a series of shutters and directed toward the body (at or near a 90deg angle)
- x-ray beam passes through the body and undergoes a process of attenuation (defined as the gradual loss of intensity as a result of passing through a medium)
- human body absorbs rays in various amounts dependent on tissue characteristics
- x-ray film sensitive to light and radiation, chemical reaction occurs causing an image to be produced in shade of gray in black film
- final image is representation of radio density of anatomical structures the x-rays have passed through
331
Radiodensity
- refers to the amount of blackening on the radiograph
| - determines how much radiation will be absorbed
332
Radiolucent Radiodensity
- does not absorb much radiation
- appears dark grey or black
- air and fat
333
Radiopaque Radiodensity
- absorbs a lot of radiation
- appears more white
- metal and bone
334
Radiodensity is determined by what
- atomic weight or composition (the greater the atomic weight, the greater the radiodensity)
- lead used as shielding device (high atomic weight)
- thickness of object (thicker the object, the more radiation absorbed = more radio dense)
335
Densograph
- radiographs are not photographs, but densographs
- they represent tissue density
- normal tissues are grey, with any observed density changes, one can assume pathology is present
- 75% of film-reading skill is knowledge of anatomy
336
Density of Tissues
- the greater the density of the tissue, the less penetration of the x-rays
- highest density tissues appear white
337
Lowest Density on X-rays
- air
- black
- lungs, trachea, bowel, thin fat, thin connective tissue, adipose
338
Lower Density on X-rays
- fat
- dark grey
- thicker adipose, multiple layers of thin tissue, osteoporotic bone
339
Neutral Density on X-rays
- watery
- mid-density
- mid-gray
- muscle, tendon, thin bones, overlapping soft tissues, blood
340
Higher Density on X-rays
- mineral
- light grey
- cancellous bone, thinner muscle, tendon, organ tissues, superimposition of thin, soft tissues, large blood vessels
341
Highest Density on X-ray
- heavy metals
- white
- thick cortical bone, dental fillings, jewelry, orthopedic hardware, zippers, buttons
342
Third Dimension x-ray Perception
- need more than one radiograph to get info about a structure
- one view is not enough
- two projections are taken at 90deg orientation
- minimizes 2D error
343
Body positioning with radiographs
- specific positioning
- provides best visualization of body area with least number of radiographs
- routine views of skeletal system
344
Viewing Radiographs
- place film on view box as if viewer are X-ray beam
- consider area x-rayed
- consider this area must be closest to film to get accurate picture
- consider the x-rays must pass through the person to get the film
345
Film Markers
- patient ID
- anatomical side markers
- Int / Ext
- WB
- erect, upright
- decubitus
- Insp / exp
- radiographers initials
346
Radiographic Density as a Quality factor
- controlled by varying the milliamperage (mA) and exposure time
- distance of body part from beam affects this well
- under or over exposure
347
Radiographic Contrast as a Quality Factor
- anatomical detail more visible on the x-ray
- greater the variation in anatomical structures, the higher the contrast
- chest radiograph = low contrast
- skeleton = high contrast
348
Contrast
- controlled by kilovoltage (kVp)
- higher the kVp, the greater the energy of the x-ray beam which causes greater entertain through the body parts
- more penetration, more uniform is the picture and will have less variation in tissue absorption and a low contrast radiograph occurs
349
General Rule with radiography Contrast
- use the highest kVp and lowest mA which will yield the best diagnostic info necessary for patient intervention
350
Radiographic Distortion
- difference between the actual object and it's recorded image
- radiographs are 30% larger than actual structure
- shape distortion: unequal magnification of structure (central ray accurate, more inclined the structure = greater distortion)
351
Radiographic Distortion causes
- beam source
- patient
- film
- alignment
- position of central ray
352
Superimposition
- occurs when anatomic structures are stacked or superimposed on one another so that the x-ray beam must penetrate multiple structures before arriving at the film plate
- this may create artificial lines, shapes, and forms that appear unrecognizable or pathological in nature

359

- can be radiopaque (barium sulfate, Iodide)
- can be dual (see gastrointestinal dual-contrast examination)
