• today one can find multi-slice machines available with CT Scan machine Dealers. The number of slices a machine has impacted the amount of time it takes to complete the examination. The advantages of a CT Scan machine with added slices are- examination times are abridged, resulting in less radioactivity exposure, pictures are more detailed, and have lesser artifacts and augmented patient outputs.

The different types of slice machines are

• 16-slice CT machines are quicker than the 4 and 8-slice machines, so x-ray clinics and radiology sections of the hospital that have a regular flow of patients could select these machines. These machines are useful for normal examinations and are useful in ER.
• CT machines with 32-40 slices are found in similar amenities as the 16 slice machine, but in distinction to the 16 slice machine, the added slices offer added coverage per gantry rotation, which reduces the amount of time it takes to complete an examination. As a consequence, the picture is not as pointedly obstructed by motion artifacts.
• The 64-slice CT machine has now become commonplace in imaging hubs and hospitals. As they take a lesser amount of time, these machines can be used for complicated examinations, such as cardiac inspections, which can now be approved. Its haste and precision make it well-suited for use in medical clinics with a reasonable to high number of patients.
• The 128-slice machine can generate complete body examinations in a matter of seconds and they deliver an amazingly clear 3D picture of any organ. Inside a typical medical environment, the abilities of these scanners are regularly extreme and needless. As a consequence, you will characteristically find them sustaining specialist practices, like cardiac sections, research hubs, or parts with very high patient traffic. 
• Use- when a hospital is buying a CT Scan machine, it must reflect on the purpose for what it is going to use it for. For general imaging purposes, a 16-slice machine must be adequate. The slice count works well for imaging hubs, ER, and hospitals. Though if you want the machine for cardiac examinations, the buyer must select a 64-slice scanner with higher hustles. This is because such machines move fast enough to capture pictures that check cardiac motion and stop motion distortion. The hospital must also safeguard that it has a Motion-Correction algorithm and Cardiac Metal Artifact Decrease Software to decrease retakes and yield more precise pictures. If the hospital treats several trauma patients, it must not select the older models that are restricted by the span of the scanning time and location, as this can be predominantly challenging for unhinged trauma patients. As an alternative, they must select 64-slice models with augmented area coverage, permitting them to perform examinations faster.
• The X-Ray Tube- As it produces X-rays Machine, the X-ray tube is one of the most dynamic apparatuses of a CT scanner, and it is expensive to replace. X-ray tubes are branded by the warmth they can resist, articulated in MHU (Mega Heat Unit). The better the MHU rating, the more warmth the tube can endure and the more inspections it can conduct. Due to the comparative expenditure of a new tube, there is substantial interest in forecasting the CT tube’s projected lifespan. However, various CT Scan Machine Manufacturers gauge it in different ways.
• Milliampere Seconds (mAs): This bids information on the length of exposures and the amount of power that has been accepted through the tube. This is the best technique for defining the tube’s remaining lifespan.
• Examination Seconds: This gauges the length of the tube’s experiences or how long the tube has been used. Though, this does not signify the amount of power or warmth passed through the tube.
• Clicks/Count: This technique of shaping CT tube count designates the number of exposures done by the tube. Though, it does not deliver the power usage used during these exposures.
• Total Patient Examinations: This is the aggregate of all person X-ray inspections that have been conducted with the tube. It does not comprise information on the span of the examinations or the amount of effort they took.
• Warranty and Installation- When purchasing CT Scanners, it is best to go for those with a guarantee as these are likely to be more dependable. Safeguard that you make the most out of your money by going for apparatus that will provide you guarantee in terms of toughness and the services arranged. Some CT Scan machine Dealers also offer fitting support for a fee or may endorse third-party connection services suppliers. Whichever choice is obtainable to you, guarantee that the connection is done well and follows the CT Scan Machine Manufacturers stipulations.
• Budgetary CT Scan Machines range from 1.5cr to 4.5 cr including accessories & table. While purchasing CT Scan Machine for hospitals the application of the machine must be useful for patients admitted in the hospitals. Higher slices rates are also high for CT Scan Machine. Generally hospitals go for refurbished CT Scan Machines with a good warranty & guarantee period at least for 2 years.

•  The CT Scan Machine which we are buying for our hospital must be user friendly for CT Scan Technician & it should not lag during scan & patient must feel safe while undergoing scanning. The base on which CT Scan Machine is Installed must have a weight bearing capacity of 6 to 8 tones.

• Radiation exposure measurements need to be taken care of while using CT Scan Machine & the walls of the room must be made up of or coated of lead material.
