Wilhelm Rontgen discovered X-rays in 1895 after obtaining the first medical X-ray of his wife's hand. X-rays are a form of ionizing radiation that can pass through objects and be captured on film. They are used widely in medical diagnostics to image bones and some internal organs, as well as in other applications. Proper procedures and equipment are needed to perform X-rays safely and obtain diagnostic images while minimizing radiation exposure to patients and medical staff.

3. -WORLD’S FIRST X RAY IMAGE
Worlds first x ray image obtained was of the Hands
of Wilhelm Rontgen’s wife on 22nd December 1895
The first x ray Photograph:
Roentgen’s Wife
“Bertha’s Hand”
--Hand mit Ringen (Hand with rings) print of
Wilhelm Roentgen’s First Medical x ray of
his Wife’s hand taken on 22nd December
1895 and Presented to “Ludwig Zehnder”
of physic Institute, “University of Freiberg”
on 1st January 1896

4. -PROPERTIES
--X-Ray photons carry enough energy to
ionize atoms and disrupt the
molecular bonds. This makes it a
type ionizing radiation.
--This ionizing property is used to kill
the malignant cells by radiotherapy
--It is absorbed by solid / radio-opaque
substances like bones and metals

5. -A simplified diagram of a water cooled X Ray tube
-PROPERTIES contd.

6. ---The X Rays interact with matter in three main ways
--Through photo absorption
--Compton scattering and
--Rayleigh scattering
The strength of these interactions depend on the energy
of X Rays and the elemental composition of the material,
but not much on chemical properties.
Since the X Ray photon energy is much higher than chemical
binding energies , photo absorption or photoelectric
absorption is the dominant interaction mechanism in the
soft X Ray regime and for the lower hard X Ray energies.
At higher energies, Compton scattering dominates
-INTER ACTION WITH MATTER

7. --1-Based on the energy of the radiations X Rays
have wide range of uses like in the Medical
field, security purposes ect.
--It is used in X Ray scanners
--X Ray crystallography
--Industrial radiography and CT scanning
--X Rays has an immense role in the medical
field
--This is diagnostic as well as therapeutic
-USES

8. DIAGNOSTIC USES
--X Ray is the most preferred tool for detecting
any bone related problem
such as
--Fracture
--Tumor
--Degenerations
--It is also used to detect other cases like
--Pulmonary Tuberculosis
--Lung abscess
THERAPEUTIC USES
--It is used in cancer treatment to kill malignant
cells

12. -RADIATION MONITOR

13. --It is a device that let us have an eye on the
amount of exposure of X Radiations to the
technician, thus enabling us to reduce the
hazardous effect of the radiation on the
human tissues
-RADIATION MONITOR contd.

14. --1-This helps to confirm the Diagnosis
--2-Helps to study the fracture anatomy
-3-Helps to study the fracture Displacement
--4-Helps to Detect Crack and stress fractures
--5-Helps to plan the treatment
--6-Helps to detect fracture dislocation
OR combination (Monteggia fracture)
--7-Helps to ascertain post-Reduction status
of fractures
--8-Helps in Medicolegal studies
-ROLE OF X RAY

15. -Before asking for an X Ray the following
points should be kept in mind
-ASKING FOR AN X RAY
--1-Both AP and Lateral views should be taken in most of
the cases
--2-Special views in some cases show the fracture better
--3-X Ray requisition must specify the area of suspension
--4-X Ray of the pelvis with both Hips should be asked for
in all cases of suspected Pelvic injury
--5-For an X Ray evaluation of the hands and feet “Antero
-Lateral and Oblique views (Not Lateral) are required

16. ---Better No X Ray is requested than one view X Ray
--X Ray is a shadow, it conceals and distorts hence
interpret X Ray with caution
--A joint above and joint below should be included
with the fracture under study
--The fracture should be middle of the exposed film
--Exposure should be adequate and the soft tissue
shadow be delineated properly
--X Ray should be read by holding the film in an
anatomical position
--Avoid un-necessary X Rays
--Check X Rays are to be taken without disturbing
the plaster cast
-BASIC RULES IN X RAY
-Points to be remembered

17. ---Most of the time, the body part that is to be seen
under X Ray is to be exposed properly i.e. the
cloth over it should be removed
--Any accessory item or jewellery on the focused part
should be removed
--Patient needs to be calm and maintain the posture
which is instructed to him / her
--Patient needs to follow the given instructions
strictly
-PATIENTS PREPARATION FOR X RAY

18. -ANTERIOR – POSTERIOR VIEW
-SOME NORMAL VIEWS
IN X RAY DIAGNOSIS
--The X-Ray beam is exposed from the anterior side of the body part.
--The beam casts a shadow on the X Ray plate that is kept behind
body part

19. -LATERAL VIEW
-SOME NORMAL VIEWS
IN X RAY DIAGNOSIS
-The X Ray beam is exposed from the Lateral aspect of the body part

20. -SOME NORMAL VIEWS
IN X RAY DIAGNOSIS
-OBLIQUE VIEW
-In this view, the X Ray beam is exposed from a plane which is
oblique to the body part on which the X Ray beam is focused

21. --Frame:- A—(AP – Elbow)
--Frame:- B—(Lateral view Elbow)
--Frame:- C—(AP and Oblique views Elbow) Medial or internal rotation
--Frame – D—(AP and Oblique view Elbow ) External Rotation
-SOME NORMAL
VIEWS IN X RAY
DIAGNOSIS

22. -Oblique view wrist is done to detect Scaphoid Fracture. The X Ray beam
is given in a plain perpendicular to a plain which is slightly slanting
-SOME SPECIAL VIEWS IN X RAY
-SCAPHOID FRACTURE

23. -SOME SPECIAL VIEWS IN X RAY
-Judet view to detect Acetabular fracture. It is a modification of oblique
View of the Hip. Here the patient’s trunk is rotated to contra – lateral
Side in relation to the hip whose image is being taken
-ACETABULAR FRACTURE

24. -Merchant view is done for “Patello – Femoral joint. It is taken in such
A way that only the image of the patella is obtained. The procedure
Is given in the picture below
-SOME SPECIAL VIEWS IN X RAY
-PATELLO FEMOAL

25. -Skyline view for Calcaneum fracture. It is taken by the same principle as the
Merchant view of Patella. The X Ray beam is directed obliquely, so that it
only casts a shadow of Calcaneum on the film

26. -(Y) VIEW OF SCAPULA
-SOME SPECIAL VIEWS IN X RAY
---It is taken perpendicularly to scapular plain from the
Lateral aspect. The X Ray image looks like the one
given below

27. -DUNN view - is an antero – posterior view of the hip with the
patient supine and the hips and knees flexed at 90 degree, the
legs abducted 15 to 20 and the femur in the neutral rotation
-SOME SPECIAL VIEWS IN X RAY

28. ---MODIFIED DUNN VIEW:- This view is the slight modification of
DUNN view, where the hip is flexed to 45 degree
--Dunn view and modified Dunn view is mainly to see the
asphericity of the femoral head, which is the cause of
premature arthritis
-SOME SPECIAL VIEWS IN X RAY

29. -Cross table lateral view is the lateral projection radiography
of a supine subject using a horizontal X Ray beam
-SOME SPECIAL VIEWS IN X RAY
-This is Mainly used to detect neonatal pneumo – thorax
hairline fracture in the neck of the femur

30. ---An X Ray view box should be used in all cases. If a fracture
is obvious
One must make note of the following points:-
-Which bone is affected ?
-Which part of the bone is affected ?
-At what level is the fracture ?
Weather he fracture is in the Upper, Middle, or Lower third
-What is the pattern of the fracture ?
=Is the fracture displaced
=Is the fracture expended to nearby joints
-Does the underlying bone appear Pathological ?
Example a Cyst, abnormal texture of the whole bone etc.
-is it a fresh or an old fracture

40. -ADVERSE EFFECTS OF X RAY
---Diagnostic X Rays increase the risk of developmental
problems and cancer in those exposed cells. X Rays
are classified as a carcinogen by both world health
organization’s international agency for research on
cancer and U.S. government.
--It is estimated that 0.4% of current cancer cases in
the United States are due s to diagnostic X Rays
and CT Scans
--That’s why when it comes to perform an X Ray on
a pregnant woman Proper women, proper
assesment of benefit versus risk is done
