An Application-specific integrated circuit(ASIC) of special chip circuits are used in ultrasonic probe array systems. The circuit architecture is to calculate the output of the ultrasonic probe signal in two different periods of time. In the odd-even mode, the mode setting module arranges one of odd ones and even probes of the address parameters in numerical order, followed by the other one of the...
This new method eliminates the possibility of false triggering in the traditional signal due to mutual cross between the ultrasonic systems. Such as: the second reflection, ultrasonic probe with the angle of the angle shift and other issues. It is the main principle for the probe geometry position after the dislocation. Each element of the probe received a drive signal does not affect the probe in...
In this paper, HV-ESD Clamp protected ultrasound transducer topology is proposed for driving multichannel medical ultrasound transducer array. High voltage power, low voltage logic and high voltage CMOS architecture were integrated in ultrasound chip. On-chip high voltage electrostatic discharge (HV-ESD) protection design in smart power technology of ultrasound chip is a challenging issue. Specially...
An intelligent data encoding algorithm to control high voltage multiplexers for multi-channel medical ultrasound applications is validated in this paper. The time interleaving scanning sequence is controlled spatially on the ultrasound transducer elements to avoid the strong interference caused by the excitation of neighbor elements. The output noise of multiplexer which is designed to enable 32-channel...
