 Summary
Emergency radiography is defined by
the imaging and imaging
management of patients who are
acutely ill and injured.
INTRODUCTION
Emergency radiography can be an exciting
,challenging as well as stressful environment for
the radiographer.
Depends on how prepared the radiographer is
to handle the situation.
Specialized trauma imaging systems reduce
the amount of time required to obtain
diagnostic images
EMERGENCY DEPARTMENT
 “Emergency
department” signifies a
specific level of
emergency medical
care.
 A medical emergency
is an injury or illness
that is acute and poses
an immediate risk to
a person's life or long
term health.
Trauma is defined as any physical damage to the
body caused by a sudden, unexpected, dramatic,
forceful, violent or accident event or fracture etc.
Emergency medical care often is the difference
between life and death.
Radiographers in the emergency department
(ED) must be prepared for a variety of
procedures on patients in all age groups

Rotating anode
Patient conditions and preparation
Closely supervise trauma patients at all times
A patient who requires examination of the
whole spine, chest & pelvis, lateral radiograph
should be performed before the anterior
posterior radiograph which avoids wasting
time in moving the tube back and forth
between exposure.
Patient preparation
To minimize risk of exacerbating the patient's
condition, the x-ray tube and lR should be
positioned, rather than the patient or the part.
Patient history must be taken into consideration
The items that might cause an artifact on the
images should be checked.
facility for proper storage of a patient's personal
belongings is required.
Responsibilities of Radiographers & RT
should develop an understanding of the
imaging equipment utilized in ER
Should know the role of the radiographer as a
vital part of the ER team,
 present the common radiographic procedures
performed on emergency patients.
Responsibilities of Radiographers & RT
Perform quality diagnostic imaging
procedures as requested
Practice ethical radiation protection
 Provide competent patient care
Equipment
To minimize the time required to acquire
diagnostic x-ray images, many ERs have
dedicated radiographic equipment
It provide greater flexibility with a minimal
patient movement. to minimize movement of
the injured patient while performing imaging
procedures
ER equipment
some ERs are equipped with specialized beds or
stretchers that have a moveable tray to hold the
l R.
This type of stretcher allows the use of a mobile
radiographic unit and eliminates the
requirement and risk of transferring an injured
patient to the radiographic table.
ER Equipment
Mobile radiography is widely utilized in the ER. (
Battery Powered & Capacitor Discharge)
C-arms are utilized for fracture reduction
procedures, foreign body localization in limbs,
and for reducing joint dislocations
Celling suspended tube, vertical Bucky, floating
table top with Bucky

Immobilization devices
 To stabilize injured patients.
 To prevent involuntary and voluntary motion
 Once injuries have been diagnosed or ruled out, the
attending physician gives the order for immobilization to be
removed, changed, or continued.
 Radiolucent foam pads, Sponges, sandbags, and the creative
use of tape are often most useful tools.
 I R holders helps to perform cross-table lateral projections on
numerous body parts with minimal distortion.

and neck brace used for
trauma patients.
Fig: B, Backboard
,brace and other
restraints are used
on the patient
throughout
transport.
Fig :C All restraints
will remain with
and on the patient
until all x-ray
examinations are
completed.
Grids
 Grids and IR holders are necessities since many projections
require the use of a horizontal central ray.
 Focused grid, lower grid ratio ( 6:1),12:1 bulky patient grids)
 Non-linear water type grid which have wider film range
and better tolerance of central ray angulation and
centering
 Correct FFD for the type of grid is used otherwise cutoff
artifact will result.
Exposure factors
 shortest possible exposure time that can be set should be
used in every procedure, except when a breathing technique
is desired.
 Radiographic exposure factor compensation may be required
when making exposures through immobilization devices, like
a spine board or backboard.
 Pathologic changes should also be considered when setting
technical factors. For instance, internal bleeding in the
abdominal cavity would absorb a greater amount of radiation
than a bowel obstruction.
Radiation Protection
 Collimation to the anatomy of interest to reduce scatter,
 Gonad shielding for the patients of child-bearing age
 Lead aprons for all personnel that remain in the room
during the procedure
 Exposure factors that minimize patient dose and scattered
radiation
 Announcement of impending exposure to allow unnecessary
personnel to exit the room
Best Practices in Trauma Patients
 Speed - Performing Quick or rapid diagnostic examination
is critical to saving the patients life.
 Accuracy - must provide an accurate images with a minimal
amount of distortion and the maximum amount of recorded
detail.
 Quality - The quality of a radiograph does not have to
sacrifice to produce an image quickly.
Gloves, mask, and gown must be properly worn.
Protect the IR and sponges and keep all equipment
and accessory devices clean
Wash hand frequently, especially between patients.
Adhere to Code of Ethics for Radiologic Technologist
and the Practice Standards of professionalism

Summary
 Emergency radiography has emerged as one of the newest
and fastest growing radiology subspecialties.
 Today, with the ready availability of cross-sectional imaging
with CT, MRI, and ultrasound, the emergency radiology
facility has become the acute diagnostic imaging center.
 Use of emergency cross-sectional imaging can expedite
patient care as well as prevent unnecessary hospital
admissions and unnecessary emergency surgery
