Scalable multimodal tomography system

Abstract

The invention relates to an expandable mode tomographic imaging system, which includes a main control module and each single mode tomographic imaging module. Among them, the main control module is responsible for the data communication function between each single-mode tomography module, and coordinates the data acquisition speed and timing of each single-mode tomography module; each single-mode tomography module can The multi-mode communication interface is connected with the multi-mode control line; use the multi-mode control line to connect the multi-mode main control chip and the control chip of each single-mode tomography module, and use the multi-mode main control chip, through the multi-mode The modal control line transmits status and instruction signals to realize the work timing and speed control of each single-mode tomography module, and coordinates the data communication between the modalities; the multi-mode main control chip adopts FPGA chip, read The level value on the status line, according to the prepared internal program, sends the start work command to each mode through the command line, and coordinates the working sequence of each single-mode tomography module.

Description

Technical field[0001]The invention belongs to the field of measurement technology, and relates to a multi-modal tomographic imaging system with expandable modalities, which can realize the free combination and expansion of different tomographic imaging modalities. The present invention takes the multi-modal tomography system as the description object, but it is not limited to this application. In other industrial processes and chemical reactions in the measurement, control and other systems of the coordinated work of multiple detection modalities, the main part of the present invention The control module and control method are still applicable.[0002]technical background[0003]Tomography technology has the characteristics of non-disturbance and visualization, which can realize the detection of complex flow media distribution parameters, visual testing and monitoring of multiphase flow processes in petroleum, chemical, metallurgy, power, energy and other industrial fields, as well as i...

Problems solved by technology

One is that it can only be applied to a specific measured medium. Once the measured medium changes, or the sensitive field distribution parameters of the measured medium change, the original multi-modal system may not be applicable.

The second is that the modality cannot be flexibly expanded and any combination of multiple modalities can be achieved. If you want to obtain more modality information, you can only redesign the multimodal tomography system
