What is computer tomography?

Computer tomography (CT) is the LATEST technological way of scanning the internal organs and mapping their functions in three dimensional image using X-rays. Computer tomography allows for more precise medical diagnosis through visualization of the dee-pest inner organs of the human body.

How do we obtain the images?

During one routine CT procedure the patient lies on a table. The source of x-rays is placed on a rotating round base – it is a round x-ray tube.The X-ray tube rotates around the patient’s body, who is comfortably lying on a table.Opposite of the x-rays lie a few detectors that absorb the x- rays passing through the patients body, and than the computer transforms the captured x-rays an image. The table moves the patient into the head of the machine where the x-ray tube and the surface detector are situated.

What is computer tomography?

Types of computer tomography:

CT with one line of detectors is called one slice or mono slice computer tomography. CT with many lines of detectors is called multislice computer tomography.For each activated image, the x-ray tube rotates around the patient and the x-rays are moving into marked area, which makes thousands of x-ray mea-surements. The computer is reprocessing the information giving adequate slices on the screen.

This machine has surpassed the overlapping of the images during scanning of separate organs of the patient.All different images in the computer are giving one final clear image that helps the doctor to see very cle-arly and to differ healthy tissue from diseased tissue.

CT scan uses different types of programs for analysis of the images. The quality of the image depends of: ► the nature of the x-rays ► the speed of each measurement ► the details of reconstructive technique (algorithm) ► the characteri- stics of the machine

-the methodology of the interpretation of data base information-The computer enables shadowing, rotation, correlation of anatomical measure-ments of the image. This information may be manipulated for more precise clini-

cal information.Differences: The conventional x-ray scan is underestimating tissue density for 5%, whilst computer tomography is calcula-ting up to 1% of tissue density or less, which makes for a mi-nimal margin of mistake in the estimation of the anatomy of the internal organs.

LIGHT SPEED 64-Slice VCT Scanner

In 21-st century medicine it is especial-ly important to be able to predict health pro-blems in each patient in a least invasive way that lasts only a few seconds.The latest generation of 64 –slice LIGHT SPEED VCT (volume computer tomography scan) Scanner is the machine that fulfills this need The detailed image 64-Slice tomography LIGHT SPEED VCT Scanner gives out shows three dimensional image of all organs (heart, lungs, stomach cavity organs etc.) and helps discover the processes that are taking place in there.This technology helps to reveal coronary dis-ease of the patient, including the heart attack, as well as the diseases of other vessels.Light Speed VCT gives good images on a be-ating heart (during 3 heart cycles) or on any other organ.It detects politrauma twice as faster than the other scanners.For the doctors this means a new powerful diagnostic weapon, which may enables even routine angiography, it can provide a rapid test after a stroke, chest pain or politrauma.

How does 64-Slice VCT Scanner function?

The test combines, fast x-rays scanning and multiplied computer tomography in order to obtain detailed images of the organs without any surgical intervention.There are some rare cases when depending of the organ or the scanned area, the patient may receive contrast medium. The contrast is needed while scanning blood vessels in order to enable good visualization of the vessels. The computer is showing the organ’s complete external and detailed internal structure by processing the

x-ray cross-sections and turning them into an organ image.,.The difference between mono slice and 64 slice computer tomography is that in one rotation of the X-ray tube around the patient, the mono slice CT makes one cross-section in width of 1mm in 3 seconds, while the 64slice CT makes 40 cross-sections in width of 0.625mm in less than one second, or just 350ms to be precise.

While examining the head, it takes 40 rotations or cross sections in 120 seconds only to get one ima-ge using the conventional mono slice tomography. In comparison, the 64 slice CT makes 40 cross sections in one rotation in less than ½ second!

Before Today

In the examination of coronary blood vessels it takes 1.5-2 hours in order to get one image using the conventional way of performing angiography, while with the 64 slice CT you can take one image only in 3.5 seconds with noninvasive technique.

In the examination of blood vessels of the brain with mono slice CT you must use a contrast medium to get an image, and the patient is radiated and the scanning is risky, while with new 64 slice CT, a three dimensional image of the blood vessels of the brain is made only for 5 seconds without any contrast medium, or at least in small quantities. Above all the patient is feeling comfortable and the risk involved is minimal.

The only way to perform examination of blood vessels of the whole body, abdominal organs, lungs, virtual colonoscopy, scan of the spine (di-agnosis of spondilosis, discopathy etc.) is with the latest 64 slice LIGHT SPEED VCT tomography.All above mentioned exams can be performed in period of 3-15 seconds, with maximal comfort and speed in gaining the results.

In the youngest population – the children, during conventional mono slice CT you must give them total anesthesia to stop all movements and fear, while using the 64 slice tomography it takes only a part of a second to perform the scanning without any requirements of drugs. In that way the risk of anesthesia is being avoided and the stress in parents as well.

What does the patient get with 64 slice computer to-mography?

► Extremely low radiation, reception of very low radiation quantity ► Precision during examination: high resolution results, details of internal parts of human body and three dimensio-nal image, diagnosis of conditions and diseases which are difficult to detect; ► Fast and exact diagnosis – fast image processing, reduction of the stress, on time and right treatment of the patient; ► Comfort – appropriate care of the patients, comfortable examination, the highest standards of health care.

What does the patient get with 64 slice computer to-mography?

Beat Cardiac – Gives illustration of the heart and coro-nary blood vessels in sub millimeter resolution during 3 continuous cycles. Light speed VCT reduces the ar-tifacts from one to another heart beat and gives good visualization of the coronary blood vessels in shorter interval of breath holding, which is particularly impor-tant in adult patients.

Triple rule out – helps the clinicians in urgent diagno-sis over critically ill patients during acute chest pain, using only one scan. This special conditions may be: aortic dissection, lung embolism and acute coronary syndrome. Stroke Work Up – during stroke, it is supposed that the patient should be treated within one hour in order to gain maximal benefit.

Benefits for the patients:

► Fast diagnosis of patients with coronary diseases► Single organ diagnosis and fast diagnosis in trauma patients

► Less stress for the patient and shorter time of breath holding► Easier approach and accommodation of the patient on the scanning table

Benefits for the doctors► Complete diagnosis of head, abdomen, spine cord, chest and other organs;

► A working platform that enables diagnosis within 5-10 minutes;► The doctor may work with the patient during the examination, while the technician is performing

the examination;► Fast diagnosis with automatic reforms of clinical cross sections;► High quality image output in only 0.35 seconds.

Benefits from CT technology

► The CT Technology enables high automated operation, designed for work of only one technician;► The scanning process is automated so that the operator has only to choose among the best images necessary for the diagnosis;► The system is performing automatic reconstruction and image archiving;► System handling with the system is very easy and simple. System handling with the system is very easy and simple.
