Computed tomography (CT scan) is a medical imaging procedure that uses computer-processed X-rays to produce tomographic images or 'slices' of specific areas of the body. These cross-sectional images are used for diagnostic and therapeutic purposes in various medical disciplines.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

20. Differences between CBCT and CT
CT ( COMPUTERIZED TOMOGRAPHY
)
CBCT ( CONE-BEAM COMPUTED
TOMOGRAPHY )
CT scanner was invented by Godfrey Newbold
Hounsfield in Hayes, England
A CT scan makes use of computer-processed
combinations of many X-ray images taken from
different angles to produce cross-sectional
(tomographic) images.
CBCT is a variation on traditional computed tomography
(CT) in which an X-ray tube and detector panel rotate
around the patient capturing data with a cone-shaped X-
ray beam instead of the "slices" CTs are typically known
for.
Images are then reconstructed using algorithms to
produce 3-dimensional images at high resolution.
21. A CT scanner consists of an x-ray tube that
emits a finely collimated fan shaped x-ray beam
directed through a patient to a series of
scintillation detectors.
These detectors measure the number of photons
that exit the patient.
The detectors form a continuous ring around the
patient and the x-ray tube moves in a circle within
the fixed detector ring.
This information is used to construct a cross-
sectional image of the patient.
All CBCT scanners consists of an x ray source
and detector mounted on a rotating gantry.
During rotation of the gantry, the x ray source
produces a divergent cone shaped radiation,
while the receptor records the residual x rays
after attenuation by patients' tissues
The x ray source and detector moves through an
arc of 180 to 360 degree to produce multiple
planar projection images.
Theses images constitute the raw primary data
which is then reconstructed by a computer
algorithm to generate cross sectional images
Fig.1 Fig.2
How it works?
25. For the image reconstruction to occur ; many
scans are progressively taken as the object is
gradually passed through the gantry.
They are combined by the mathematical
procedure known as tomographic
reconstruction.
Components of image production are X-ray
generation and X-ray detection: Image
sensor- PSP (photo stimulable phosphorus
plates), CCD sensors, FPD (flat panel
detector.

27. CT CBCT
Evaluation of extent of any
suspected pathology in the head and
neck, including tumors, cysts and
infection.
Determination of location and extent
of facial fractures.

In the Developing Dentition :
Localization of an unerupted tooth .
Assessment of external resorption in
relation to unerupted teeth .

Assessment of root canal anatomy in
multi-rooted teeth .
Planning surgical endodontic
procedures .

tissue detail is not required.
Planning orthognathic surgery to obtain
three-dimensional datasets of the craniofacial
skeleton.
Assessment of the bony elements of the TMJ.
30. CT CBCT
CT eliminates the superimposition of
images of structures outside the area of
interest.
Because of the inherent high-contrast
resolution of CT, differences between
tissues that differ in physical density by
less than 1% can be distinguished.
Data from a single CT imaging
procedure consisting of either multiple
contiguous or one helical scan can be
viewed as images in the axial, coronal,
or sagittal planes, depending on the
diagnostic task. This is referred to as
multiplanar reformatted imaging.
Rapid scan time.
Beam limitation.
Image accuracy.
Reduction in patient radiation dose
when compared to medical CT.
Multiplanar reformatting
3-dimensional volume.
Better images with good spatial
resolution.
Economical, comfortable and safe.
31. CT CBCT
Disadvantage
s
Time consuming.
Expensive for routine clinical
use.
High radiation exposure.
Expensive equipment and
hence is not always
accessible.
Poor contrast resolution,
thus soft tissue cannot be
viewed.
Artifacts.
Image noise.
32. CT CBCT
Traditional CT uses a high-output, rotating
anode X-ray tube.
Cone beam tomography utilizes a low-
power, medical fluoroscopy tube that
provides continuous imaging throughout the
scan.
Produces a single slice image per scan.
Each slice must overlap slightly in order to
properly reconstruct the images
Produces the complete volume image in a
single rotation
Slower due to spiral motion.
Scan time is longer.
The single-turn motion image capture used
in CBCT is quicker than traditional spiral
motion of CT.
Average time for one bet scan may vary
from 7-30 seconds.
33. CT CBCT
Has high radiation dose.
The average medical CT scan of the oral
and maxillofacial area can reach levels of
1,200- 3,300 micro sieverts to collect
adequate formation.
Has lower radiation dose as a result of no
overlap of slices.
Radiation exposure using the standard full
field of view from a CBCT machine is 36
micro sieverts.
there is overlapping of radiation No overlap of slices
34. CT CBCT
Only one jaw can be visualized at
one time.
Both jaws can be imaged at the
same time.
36. CT CBCT
Cost is high Cost of equipment about 3 5 times less than
traditional medical CT
Can cause claustrophobia The open design of the cone beam CT
eliminates claustrophobia and enhance
patient comfort and acceptance
