Application type

Whole body permanent magnet open MRI system

Introduction to technology of product

mStar 4500 MRI is the world's first 4500 Gauss whole body permanent magnet open MRI system, which is a milestone in the history of MRI. At 4500 Gauss, XinAoMDT's mStar 4500 surpassed the open MRI strength limit predicted years ago for permanent magnet systems.

mStar 4500 MRI system is a brand new product benefiting from the companies' patented dynamic balancing technology, whose design philosophy is based on targeting the electromagnetic field. This is achieved by integrating the design of magnet, gradient and RF systems into one process. mStar 4500 MRI is characterised by its' high-quality images and fast acquisitions, making the clinical applications of advanced technologies feasible in low-fields.

MDT is the first company in the world to bring out some of the most talked about innovations in MR technology such as

• Diveded Current Active Shielding Technology (DCAST) which will reduce the addy current and residual magnetization.
• High order Active Shimming (HAOS) this helps in preventing field drift and thus improve homogeneity of the magnet.
• High Flux Efficiency Pole Design (HFEPD) this technology will help to maintain field strength vs weight of the magnet making mstart 4500 one of the lightest available in the world.
• Mstart 4500 has homogeneity less than 0.9ppm, one of the best so far among permanent MRI designs.
• The gradient strength, which is the critical parameter for high definition quality imaging like EPI, DWI is 25mT/m with a slew rate of 55mT/m/s, making MDT one of the most technically perfect systems.

Units Installed in India

SANRAD Medical Systems installed their first mstar 4500 system in India at Megavision, pune where the customer was thinking initially of a high field Supercon system. After seeing the demo images and going through the data sheets customer was convinced of MDT's superior design and quality and decided in favour of mastar 4500

Megavision is one of the primier imaging centre which caters the needs of a large number of patients and highly qualified consultants in and around pune.

SANRAD MDT engineers designed a spacious magnet and equipment room as per customer wish and completed the installation in planned one month time frame.

First trial images were very satisfactory and was matching what we have in mind from a high field open MRI, said Dr. Bhate, Director of Megavision.

"System operating system is windows XP based and is very friendly, You can almost learn the system in one day to operate" .said Mr.Sameer Deshmukh, director of MR imaging at Megavision.

"We have at least 3 confirmed order for 4500 in the first quarter of 2009 and new upgraded software is being tested now in the factory which will further enhance image quality and user friendliness. We have great expectation about this product becoming a big success in India", Added Som Panicker who is recently taken over as Head of MR Product division of SANRAD MEDICAL SYSTEMS

Best Technology MRI backed by SANRAD

SANRAD after making big success with ore than 250 CT installations in INDIA decided to enter in OPEN MRI market and for this they have evaluated more than 10 new MRI products from various manufactures.

We have carefully examined what a higly qualified n Indian Radiologist looking in an MRI and MDT matches their expectations. We have spent more than two years evaluating this product before entering an exclusive agreement with MDT, says Mr.Ratish Nair, Managing Director of SANRAD Medical Systems.

We want to be No1 in our product segment and we have learned from our competitor's success as well as failures and designed our business and product strategy.. We have hired some of the best talents with long experience in OPEN MRI recently to do serious business in India and neighboring countries.

We are a Customer first company and the focus is not just on the product but on customer and what they need from our product and company. He added

In short, MDT is the perfect answer to High Field open MRI and it is product matching some of the quality so far achievable only in Superconducting.

Testimonials

Dr Vivek Yadkikar, Hi-Tech Institute of Imaging & Research, Latur, Maharashtra

I am an old customer of Sanrad. I am using refurbished CT scanners of Toshiba, supplied and maintained by Sanrad since last eight years. About eight months back, I have purchased MRI machine from them.

Currently, I have two spiral CT scanners and one MRI machine supplied by Sanrad. It has got fast acquisition time and very good image quality. The examination time is short and the open design is quite comfortable for the patient. The image quality is exceptionally excellent. The diffusion weighed images are excellent and are best in the permanent magnet category.

The machine is very cost-effective for its performance. We are doing all routine and advanced imaging work on this machine since last eight months. We are very happy with its performance. The other most important aspect is the most reliable service of Sanrad. Overall, we are happy with the machine. The area of improvement according to me is in few musculoskeletal studies.

Dr Kedar Bhate,Megavision Scan Centre, Pimpri-Chinchwad, Pune

I would say, it's a very good machine. It is an open magnet 0.45 tesla. Other machines are closed, this is an open one. It makes the patients very comfortable. They don't feel claustrophobic. It is comparable to 1.5 tesla supercon machines. I bought this machine about a year-and-half ago.

It is cost-effective. It doesn't need helium. So far, there has been no breakdown, the power con is also very low. One can run the entire machine on a single point. It is also user friendly.

The only disadvantage or the area of improvement is the scan time. The scan time is 25 minutes. It can be reduced to 15-20 minutes using high-end softwares.
