3. Brief History of X-rays
• Discovered by Wilhelm Conrad Roentgen in 8
November 1895.
• Roentgen observed X-rays while experimenting
with cathode rays in a vacuum tube.
• Received the first Nobel Prize in Physics in
1901 for his discovery.
• X-rays revolutionized medicine by providing a
non-invasive method for imaging the internal
structures of the body.

4. X-ray Production Mechanism
X-rays are produced when high-speed electrons
strike a target material.
The process involves:
• Electron acceleration: Electrons are accelerated
from the cathode to the anode within an X-ray tube.
• Target interaction: Electrons collide with the
target material (usually tungsten) on the anode.
• X-ray emission: Energy from the collision is
emitted as X-rays.

6. Types of X-ray Production
Characteristics of X-ray Production:
1. X-rays are a form of electromagnetic radiation
with high energy and short wavelengths.
2. They are produced when high-energy electrons,
accelerated by a voltage, collide with a target
material.
3. X-rays can penetrate through soft tissues but are
absorbed by denser materials like bone and metal.
4. They are used in various fields such as medicine,
industry, and research for imaging and analysis.

7. Bremsstrahlung X-ray Production:
1. Bremsstrahlung, German for "braking radiation," occurs
when fast-moving electrons are decelerated by the electric field
of atomic nuclei.
2. During this process, kinetic energy is converted into
electromagnetic radiation, producing a continuous spectrum of
X-rays.
3. The energy of the emitted X-rays depends on the initial
kinetic energy of the electrons and the strength of the electric
field.
4. Bremsstrahlung X-rays are utilized in medical imaging,
industrial radiography, and security scanning.

8. Components of an X-ray Tube
An X-ray tube consists of:
• Cathode: Emits electrons through thermionic
emission.
• Anode: Target material where X-rays are
generated.
• Glass or metal envelope: Encloses the cathode-
anode assembly in a vacuum.
• Cooling system: Prevents overheating during
operation.
• Focusing cup: Focuses electron stream towards
the anode target.

9. Types of X-ray Tubes
There are two primary types of X-
ray tubes:
• Diagnostic X-ray tubes: Used in
medical imaging for producing
diagnostic images of the body.
• Industrial X-ray tubes:
Employed in non-destructive
testing, quality control, and
security screening.

10. Medical Applications of X-ray Tubes
X-ray tubes play a crucial role in various medical imaging modalities, including:
• Radiography: Capturing still images of the body's internal structures.
• Fluoroscopy: Real-time imaging for procedures like angiography and gastrointestinal
studies.
• Computed Tomography (CT): Producing detailed cross-sectional images of the body.
• Mammography: Screening and diagnosing breast cancer.
• Interventional Radiology: Guiding minimally invasive procedures.

11. Radiography: It started when Wilhelm Conrad Roentgen discovered
X-rays in 1895
Fluoroscopy: It was invented by Thomas Edison in 1896, shortly after
the discovery of X-rays by Wilhelm Roentgen in 1895
Computed Tomography(CT): The first clinical CT scan of the human
brain was performed in 1971 using a scanner invented by Sir Godfrey
Hounsfield, who shared the Nobel Prize in Physiology or Medicine in
1979 with Allan McLeod Cormack for the development of computerized
Mammography: The first mammography study was performed by German
surgeon Albert Salomon in 1913, on 3,000 mastectomies.
Interventional: Interventional radiology was conceived on Jan. 16, 1964,
when Charles Dotter, MD, percutaneously dilated a stenosed segment of
the superficial femoral artery in an 82-year-old woman with gangrenous
ischemia who refused leg amputation.
