A method for controlling multimodal tomography

Abstract

The invention relates to a multi-mode tomography control method. An applicative tomography system comprises a main control module and single-mode tomography modules. The method comprises the steps that when the main control module is powered on, a finite state machine is started, and according to the requirement of the finite state machine, through a mode command line, a pulse triggering signal issent to the specific single-mode tomography module which needs to start working; and after receiving an instruction signal, the specific single-mode tomography module starts to work for a complete measurement period, wherein the complete measurement period is defined as follows: the specific single-mode tomography module performs complete excitation and measurement on the cross sections of all sensor arrays contained in the mode once, and acquires data needed for reconstructing all cross section images in the mode; and during the working, the tomography modules, through a state line, continuously send working state signals to a multi-mode main control chip, and until the complete measurement period is completed, continuously send working stop signals.

Description

Technical field[0001]The invention belongs to the field of measurement technology, and relates to a multi-modal tomography system with expandable modalities, which can realize the free combination and expansion of different tomographic imaging modalities. The present invention takes a multi-modal tomography system as the object of description, but is not limited to this application. In other industrial processes and chemical reactions, the main part of the present invention is the coordinated measurement and control of multiple detection modalities. The control module and control method are still applicable.[0002]technical background[0003]Tomography technology has the characteristics of non-disturbance, visualization, etc., 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 in biology, medical, etc. The field...

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
