Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.

听觉脑干诱发电位(Auditory Brainstem Response，ABR)为微伏级人体生理参量，采用TI公司的DSP TMS320F2812，通过D/A与高精度运算放大器，生成听力级可调整的掩蔽白噪声与短纯音TB进行刺激，同时对诱发脑电进行放大、滤波、并使用TMS320F2812的A/D进行信号采集与处理，得到数字化的脑干诱发电信号。

Though nowadays microwave therapy apparatus has realized digital control technically, the control result is not perfect because of the characteristic of microwave source and other factors. With the highly informatization of medicine, all kinds of medical apparatuses need computers to manage the medical data. The new kind of microwave therapy apparatus in this thesis has not only realized the steady control of microwave output power, but also developed a remedial record database management system based on LabVIEW, which has realized the medical informatization.

目前的微波治疗机虽然技术上实现了数字化控制，但是由于微波源本身的特性以及其它因素，控制效果并不理想；随着医疗信息化的快速发展，各种医疗仪器还需要进行医疗数据的计算机管理，本文介绍的新型微波治疗机，不但实现了微波功率的控制调节稳定，而且开发了基于LabVIEW平台的病例资料档案的数据库管理系统，实现了医疗的信息化管理。
