What are the advantages and disadvantages of DR and CT produced by Siemens, GE, Philips and Kodak?

I'll give you some advice on these things, and I hope you can adopt them:

1, these companies have their own strengths. Siemens is a leader and expert in radiation products. Its main business is CT, magnetic resonance, DR, nuclear medicine and so on. Choose Siemens to buy radiation products. The equipment made in Germany has good quality, good image, low dose and advanced technology. GE's main business is ultrasound and anesthesia. If you buy ultrasound and anesthesia, GE is good. GE's radiation products are the worst among several manufacturers, not as good as Toshiba of Japan. Philips' main business is ultrasound and monitoring, but large 16 row CT and suspended DR are not bad, and the product quality is better than ge, but slightly worse than Siemens.

2. In addition, products: The components of CT and DR of Siemens and Philips are basically self-produced, such as high-voltage generators, electron tubes and detectors, with good matching and good imaging quality. Both DR flat panels are Trixll, but Siemens' update, Siemens' advanced CT technology, complete product line and numerous users. Even the institute of Chinese Academy of Sciences is using Shuang Yuan CT of Siemens and 16 of Philips. GE's CT and DR are not so good. There are many purchased accessories, which have poor matching and high failure rate. The quality of CT images is poor, the technology is backward, and the appearance is particularly ugly. GE's detector is also very poor. GE's DR adopts industrial flaw detection flat panel, with pixels basically below 4 million, poor image quality and high radiation dose, while Siemens and Philips flat panels are 9 million pixels, with low dose and high radiation dose. Ruike's words are mainly film suppliers, but CT doesn't. DR is also purchased parts assembly. Ruike's products are outsourced except flat panels, so it is recommended not to consider them.

3. Model: Siemens CT includes: spirit (low-end), emotion series (mid-end), perspective series (high-end) and clarity series (ultra-high-end); Siemens' DR includes: Ysio series (ultra-high-end), Fusion series (high-end) and Select (mid-end); Philips CT includes: MX series (low-end), Brilliace series (high-end) and ingenuity series (high-end); Philips DR: Essenta (low-end), DD2.0 series (mid-end, a little old), DD3.0 series (high-end); GE's CT: Brivo series (low end), optima series (middle end) and HD series (high end); GE's dr: brivo series (low end), Tian Fei series (mid end) and XR series (high end).

4. When purchasing, it is recommended that the hospital check it carefully. Starting from the product itself, considering the quality, matching, image quality and advanced technology, I suggest Siemens for MRI, Siemens for ct and Siemens and Philips for DR.

In addition, if you choose products of the same grade, I suggest looking at the nature of the manufacturer. After domestic assembly, the production nature is different, and the product quality is very different: Siemens is Shanghai Siemens Medical Equipment Co., Ltd. (a wholly-owned enterprise), which is assembled with German parts in Shanghai, and the standard is German standard; Philips is Suzhou Philips Medical Equipment Co., Ltd. (a wholly-owned enterprise), and Philips accessories from the United States and the Netherlands are assembled in Suzhou, with European standards; GE is Beijing Hangwei General Electric Co., Ltd. (joint venture). Hangwei Company is the major shareholder, and it purchases parts all over the world, so the product stability and matching are slightly poor.
