Are EEG machines and brain topographers the same thing?

To be precise, they are not two kinds of equipment. An EEG machine is a mechanical device, while a topographic brain mapper is an electronic device. Both of them are used for EEG examination, one is to produce EEG waveforms, and the other is to display the topographic map (three-dimensional) analyzed by EEG waveforms.

But at present in our country, in fact, the two names are said to be the same kind of equipment, because now there is very little use of mechanical electroencephalography machine, all computerized electroencephalography workstations, and electroencephalography workstations, that is, you can record the electroencephalography waveforms can be analyzed by the electroencephalography topographic maps, so it's the same equipment, but only two kinds of names, the domestic health care market is not very standardized, the division is not very clear only. The two are the same device, only two names, the domestic medical market is not very standardized, the division is not very clear.
