How is large medical equipment categorized? Than how for category A, category B?

As noted in my understanding: three ministries (Ministry of Health, the National Development and Reform Commission, the Ministry of Finance) in 2005 jointly issued "large medical equipment configuration planning and use of management methods", which of the A, B equipment as follows:

A:

1. X-ray positron emission electron computed tomography (PET-CT, including positron emission tomography that PET). ).

2. Gamma-ray stereotactic treatment system (gamma knife).

3. medical electron cyclotron acceleration system (MM50).

4. proton therapy system.

5. Other unit price of 5 million yuan and above, large-scale medical equipment.

Category B:

1. X-ray computed tomography (CT).

2. Medical magnetic **** vibration imaging equipment (MRI).

3. digital subtraction angiography X-ray machine (DSA).

4. Medical electronic linear gas pedal (LA).

5. single photon emission computed tomography (SPECT).

A large-scale medical equipment purchases need to be approved by the State Ministry of Health, issued by the configuration license.

Class B large-scale medical equipment subject to approval by the provincial health administrative department, issued by the configuration license.

No configuration of the license can not be purchased, or seriously dealt with.

Other large-scale equipment on the classification of different units around \, more or less divided by the amount of acquisition costs.

Immunoassay analyzer is just a common test equipment.
