A computed tomography (CT) scan uses X-rays to produce detailed images of the inside of the body. During the scan, the patient lies on a table that slides into a large circular machine. The machine rapidly rotates around the patient and takes images from different angles, which are combined by a computer to produce cross-sectional images of tissues and organs. CT scans can help diagnose medical conditions by revealing abnormalities that may not be visible on regular X-rays.
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.

Taming the ever-evolving Compliance Beast : Lessons learnt at LinkedIn [Strat...Shirshanka Das
Just when you think you have your Kafka and Hadoop clusters set up and humming and you’re well on your path to democratizing data, you realize that you now have a very different set of challenges to solve. You want to provide unfettered access to data to your data scientists, but at the same time, you need to preserve the privacy of your members, who have entrusted you with their data.
Shirshanka Das and Tushar Shanbhag outline the path LinkedIn has taken to protect member privacy in its scalable distributed data ecosystem built around Kafka and Hadoop.
They also discuss three foundational building blocks for scalable data management that can meet data compliance regulations: a centralized metadata system, a standardized data lifecycle management platform, and a unified data access layer. Some of these systems are open source and can be of use to companies that are in a similar situation. Along the way, they also look to the future—specifically, to the General Data Protection Regulation, which comes into effect in 2018—and outline LinkedIn’s plans for addressing those requirements.
But technology is just part of the solution. Shirshanka and Tushar also share the culture and process change they’ve seen happen at the company and the lessons they’ve learned about sustainable process and governance.
What is a Brain CT Imaging Perfusion Study?Carestream

Best CT Scan Centre of Delhi | Ganesh Diagnostic & Imaging Centre Pvt Ltdganeshdiagnostic2
A CT Scan typically combines various rotating X-Rays along with hi-end computerised processing to initiate a more detailed ‘picture’ of the inner structures of a body – including bones, tissues, and organs. A CT Scan is generally done on a patient's spine, heart, head, chest, abdomen, face, and knee. During a CT Scan, the body is made to pass by a tunnel-like machine that rotates through a 360-degree arc as it takes pictures in rapid succession. These images are eventually fed into a computer to produce an ‘all-around’ 2D snap of any part of the body. While the process of CT scan starts the contrast (substance) is taken by mouth or through an injection to see all the organs more clearly.

Computer tomography (CT), originally known as computed axial tomography (CAT or CT scan) and body section rentenography.
It is a medical imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation.
The word "tomography" is derived from the Greek tomos (slice) and graphein (to write). CT produces a volume of data which can be manipulated, through a process known as windowing, in order to demonstrate various structures based on their ability to block the X-ray beam.
CT scans also termed as computer tomography, is an imaging test that involves taking the circular images of the body and then produces what a picture on the computer that looks like a slice through the body.
There are many different imaging techniques used in medicine and other fields. Some examples include X-ray imaging, magnetic resonance imaging (MRI), computed tomography (CT) scans, ultrasound, and positron emission tomography (PET) scans. These techniques all work in different ways to produce images of the inside of the body or other objects. For example, X-rays use radiation to create images, while MRI and CT scans use powerful magnets and computers to produce detailed images of the body's internal structures. Ultrasound uses sound waves to create images, and PET scans use radioactive tracers to create images of the body's metabolic activity. These imaging techniques are often used in conjunction with one another to provide a comprehensive view of a patient's condition.
The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

3. Ct scan: basic
• Also known as CT or CAT scan.
• Uses x-rays to make detailed pictures of
the structure inside the body.
• During the scan you will lie on a table
that is attached to the scanner.
• Large doughnut shaped machine
4. CT scan: Basic
• CT's primary benefit is the ability to
separate anatomical structures at
different depths within the body.
• A form of tomography can be
performed by moving the X-ray source
and detector during an exposure.
5. Ct scan: Basic
• Anatomy at the target level remains
sharp, while structures at different
levels are blurred.
• By varying the extent and path of
motion, a variety of effects can be
obtained, with variable depth of field
and different degrees of blurring of 'out
of plane' structures
6. Computed tomography scan is an useful machine
which can see diagnosis of the disease on the patient
where others examination still did not see clear.
A patient is receiving a CT scan for cancer. Outside
of the scanning room is an imagine computer that
reveals a 3D image of the body’s inner area.
A patient is moving during the scan, so the picture gets blurring.
That is why you may be asked to hold your breath during the
scanning.
Any motion, whether breathing or body movements can lead to
artifacts on the image.
7. Benefits by using ct
scan
• It’s painless, noninvasive and accurate.
• It’s fast and simple; e.g in emergency cases, they can reveal internal
injuries and bleeding quickly enough to help save lives.
• Less sensitive to patient, than MRI
• After CT examination no radiation remains in patient’s body.
8. Risks by using ct scan
• Always a slight chance to get cancer.
• In general, CT scan is not recommended for pregnant women unless
medically necessary because of potential risk to the baby.
• There is a chance of allergic reaction to the dye.
