A CT Scanner refers to Computed Tomography. CT scan uses X-rays to make detailed pictures of parts of your body and the structures inside your body.

CT Scanner are categorized technically by the number of slices or scans or images it can take per rotation . The single slicer takes one image per rotation and is the bottom most in the ladder.

The hierarchy goes as : 1( single), 2 ( Dual) , 4 ( Quad) , 6, 8, 16, 32, 40, 64, 128, 256, and 512 scans/sec.

What is it for?


CT scans are vital for detecting terminal diseases like brain tumors, cancer,neurological problems and other underlying abnormalities of the body, organs, bones, soft tissue and blood vessels typically provide greater detail than traditional x-rays, particularly of soft tissues and blood vessels. CT scanning provides more detailed information on head injuries, stroke, brain tumors and other brain diseases than regular radiographs (x-rays).



Quickly identify injuries to the lungs, heart and vessels, liver, spleen, kidneys, bowel or other internal organs in cases of trauma.

It successfully guides biopsies and other procedures such as abscess drainages and minimally invasive tumor treatments.

Plan for and assess the results of surgery, such as organ transplants or gastric bypass.

It helps in stage, plan and properly administer radiation treatments for tumors as well as monitor response to chemotherapy.

Aids in Measuring bone mineral density for the detection of osteoporosis.

A C.T scan is the doctor’s guide to figure out what is going inside the patient’s body, depending upon the extent of the problem, different scan may be required.

There are various types of scans that are available depending upon the need of the patient such as

What should an ideal CT scanner contain?

The Application of CT Scanners depends on Scope and Size of Hospitals and Diagnostic Centres.  A effectiveness of CT Scanner depends on the number of Images / Scans it can take per second.

Smaller hospitals and nursing homes do not require a very high end CT as they do routine scanning more , and that  too 80-90% of cases are head cases .

  • It should be fast in processingC.T scanner contain
  • Have agood memory storage.
  • Starting up time should be low
  • Scan volume should be high
  • Irrespective of the type of CT scanner selected the most critical element in the entire process of selection and utilization of ascanner depends on the availability of service in the local region and the type of service contracts. One must watch out for situations in which a manufacturer may lower the cost of its scanner to compete with other manufacturers but indirectly make up for the loss of the scanner cost by levying higher rates for service contracts.

Therefore, examining the type of service available in the region

And the type of service agreement with a manufacturer is crucial at the time of selection.

As CT Scanner Manufacturing companies have stopped manufacturing the 1,2,4 slice CTs , and are usually starting from 16 slice onward.

For the High End CT Scanners above 16 slice onwards the initial cost and running cost is quite substantial and is not viable for smaller hospitals and diagnostic centres.

With the advances in science and technology, medical field has seen significant growth.  Precision and accuracy are the latest buzz words in medical field.  Gone are the days where doctors have to either rely on information from patient or by their physical examination while diagnosing a disease.  In this new age, doctors heavily rely on medical equipment which provide precise and accurate information about the disease or the medical condition of a patient.  Advances in science made it possible to increase the efficiency of medical equipment.  These changes in the efficiency are clearly noticeable from as small a device as stethoscope to as big a machine as CT scan.

Internal infection because of various medical conditions or anatomical damages to human body were difficult to identify and pinpoint until a few decades back.  But thanks to the CT scanners, the job of doctors has been made much easier.  A CAT scan or CT scan produces cross-sectional images of a specific area with computer-processed combinations of multiple X-ray images taken from different angles as source.  These images provide the ability to see the inside of an object or body part without the need to cut the body part or object

The precise, accurate and clear information a CT scanner provides made its usage significantly increase over the last two decades in many countries across the world.  In the year 2007, in US alone, a staggering number of 72 million scans were performed with the help of CT scanner.  The use of CT scan is not limited or restricted to any part of the body.

ct scanner

It can used to diagnose various diseases that fall under cardiology or neurology or pulmonology.  There are multiple benefits associated with CT scan.  CT scan provides the ability to capture only the area of interest as part of the image by eliminating the superimposition of images of structures that are not part of area of interest.  A CT scan images are of high-contrast resolution which translates into the ability to differentiate between tissues with a difference in physical density by less than 1%.  Multiplanar reconstruction is the most important benefit wherein a volume of image is built by stacking the axial slices.  Multiple other 3D rendering techniques such as surface rendering, volume rendering and Image segmentation increase the image quality.

The increasing growth of CT scan market has having the reverse effect on the X-ray market which is getting phased out gradually.  This trend of increased growth of CT scan market having a diminishing effect on X-ray is more evident in developed markets such as US and Western Europe.  In emerging markets such as India, Russia and Israel etc., the growth potential for CT scan market is very high.  This is due to the fact that X-ray machines are still extensively used among the emerging markets.  Governments across the emerging markets have realized the importance of a nation with healthy population.  This has led to increased budgetary spending in healthcare industry in the emerging countries.

CT scanners

CT scanners are extensively used in imaging centers, hospitals and clinics.  Currently, 16 and 64 slice scanners enjoy great deal of popularity among the service providers.  However, 320 scanner systems are also available.  Some of the dominant players in the CT scan market include Toshiba Medical Systems, Siemens, Trivitron Technologies, Philips Healthcare and GE Healthcare.  These major players in their economic interest to grab the market are also investing heavily in their R&D in order to bring more and more enhanced features with their products.  As we advance in science and technology field, we can be assured that CT scanners will come with innovative, safe and enhanced features that make the job of diagnosing a disease by doctor a cake walk.


Gone are the days when surgeons had to cut open human body to understand the anatomy and physiological processes of human body in both health and disease.  The latest in science and technology has made it a reality to examine the physiological processes and anatomy of human body without a single cut.  MRI or Magnetic resonance imaging is an imaging technique that falls under radiology with the help of which pictures of anatomy or physiological processes can be formed.  Radio waves, strong magnetic fields and field ingredients may be used to generate these images.

MRI scanners are considered superior to X-rays and CT scanners.  Some of the risks that come associated with the use of MRI scanners is people need to go into a tube kind of structure apart from bearing the louder sounds.  This can be quite a discomfort for people who are claustrophobic.  Also, MRI scanners may take more time when compared to CT scanners to generate the image.  Further, people with medical implants and other metal implants may not be able to undergo MRI scan safely.

MRI falls under the science of nuclear magnetic resonance.  Some atomic nuclei have the ability to absorb and emit radio frequency energy when placed in an external magnetic field.  When it comes to clinical and research MRI, hydrogen atoms are the most commonly used in order to generate a radio-frequency signal that is detectable and which can be received antennas that are placed in close proximity that is put under examination.


The advantage of using hydrogen atoms here is that they are abundantly present naturally in humans.  Water and fat present in humans have increased concentration of hydrogen atoms.  Radio wave pulses excite the energy transition nuclear spin with magnetic field gradients localizing the signal in space.  The parameters of pulse sequence can be altered thus generating different contrasts between tissues which are dependent on the relaxation properties of hydrogen atoms.  Widely used in clinics and hospitals, this equipment is critical in medical diagnosis, disease staging and follow-up.

Various specialty departments of medicine such as neuroimaging, cardiology and gastroenterology use MRI.  MRI is the choice of tool in order to perform investigation for neurological cancers.  Higher resolution and better visualization technique make it the most preferred tool.  MRI scans provide high contrast resolution images of grey and white matter and hence it stands out to be the obvious choice for many disease conditions such as dementia, epilepsy and other infectious diseases.  In cardiology, cardiac MRI is widely used as a complementary to other imaging techniques.  It is extremely helpful in the assessment of serious heart ailments such as congenital heart disease and cardiomyopathies etc.

By 2021, the MRI market is expected to reach USD 7 billion by 2021.  Top MRI manufacturers include, GE, Philips, Hitachi and Siemens.  The MRI market has become extremely competitive with vendors adopting various strategic initiatives both on the business end as well as on the research side.  On the business front, companies adopting merging and acquisition strategies in order to make their presence across the globe and also to make entry in new markets.  On the research front, manufacturers such as Philips have launched MRI/PET imaging systems into the market.  These systems without ionizing radiation combine functional imaging data and anatomical imaging to deliver high quality soft tissue characterization.  Besides the above listed factors, some of the MRI System Market Drivers are emergence of hybrid imaging technologies, advent of MRI-compatible pacemakers and development of superconducting magnets.  With so many advantages, the MRI scan definitely takes a more preferential tool position among the medical community for disease diagnosis and health assessment.
