ADAPTIVE CALIBRATION FOR TOMOGRAPHIC IMAGING Russian patent published in 2016 - IPC A61B6/03 

FIELD: medicine.

SUBSTANCE: group of inventions relates to radiological technologies for tomographic imaging. Tomographic imaging method comprises steps: collection of visualisation data using active visualisation means, updating of calibration based on the current information on radiological tomographic imaging device, calibration of visualisation data using updated calibration and reconstruction of calibrated visualisation data to form an image. System for tomographic imaging comprises a multimodal radiological tomographic imaging device, a calibration module and a module for image reconstruction. Data medium storing commands for implementing the method of tomographic imaging, comprises the following steps: instruction of radiological tomographic imaging device to collect data of CT imaging using a detector matrix, determining of a constant scale of intensity, adjustment of scanning pattern in air by means of a certain constant intensity scale, calibration of collected data of CT imaging to form calibrated CT imaging data and reconstruction of the calibrated CT imaging data to form an image.

EFFECT: use of the inventions enables higher accuracy of data of radiological tomographic imaging.
