Zero-line Automatic Calibration and Application for the Intelligent Medical Instrument / 医疗卫生装备

ABSTRACT

The intelligent level of the modern medical equipments is higher than before and the automatic calibration circuits are largely used. The control circuit of the intelligent equipments is quite complicated and its working modes have been simplified to four-terminal or double terminal nets. The intelligent medical equipments such as CT, MRI, DR, PET/ CT have more chances to have some "soft" errors that are usually related to the zero-line calibration. In actual use, it can be noticed and performed, and the detecting and servicing for the medical equipments can be much easier than before.
