EXRH-3200A Two-Depth Transcranial Doppler (TDTD)

EXRH-3200A Two-Depth Transcranial Doppler (TDTD)
Characteristics:
Humanization design, simple, practical and easy to operate.
High-performance ultrasound transmitter and receiver system designed by ourselves could detect the good quality Doppler spectrum quickly, avoiding misdiagnosis and missed diagnosis effectively.
Adopting WIN XP operator and self-developed software system with independent intellectual property rights.
Doppler spectrum may be stored, ready reference, re-edit.
The monitoring parameters will be automatically calculated by dynamical calculating scale.
Built-in expert database of each age group for reference.
Adopting advanced digital technology, independently developed four segments M waves and automatically recognize the depth of the flow of energy and direction.
Single and dual window display modes are available for easy observation.
