SIMULATION OF OBJECTS IN AN ATLAS AND REGISTRATION OF PATIENT DATA CONTAINING A SPECIFIC STRUCTURE TO ATLAS DATA

摘要

A data processing method for registering patient data containing normal patient data and specific object data to atlas data not containing this specific object data, the method comprising the following steps performed by a computer: a) acquiring the patient data which comprises anatomical information of the patient including normal patient data and the specific object data of the patient; b) segmenting the specific object data in the patient data; c) acquiring atlas data; d) acquiring meta-information about components of the atlas data; e) performing a fusion of the acquired patient data excluding the segmented specific object data and the atlas data to obtain registered atlas data; and f) simulating the growth of a simulated specific object within the registered atlas data using the registered atlas data and the meta-information about components of the atlas data being adjacent to the area of the specific object to obtain registered atlas data containing a simulated grown specific object.

1. A data processing method for simulating a change of growth of a specific object data describing or representing a location within normal patient data, the method comprising the following steps performed by a computer:
a) acquiring the patient data which comprises anatomical information of an associated patient including normal patient data and the specific object data of the associated patient; b) segmenting the specific object data in the patient data; c) acquiring atlas data; d) acquiring meta-information about components of the atlas data; e) performing a fusion of the acquired patient data excluding the segmented specific object data and the atlas data to obtain registered atlas data; and f) simulating the growth of a simulated specific object within the registered atlas data using the registered atlas data and the meta-information about components of the atlas data being adjacent to an area of the specific object, wherein in the simulation of step f) a set of rules for simulating the change or growth of the specific object is used, wherein the meta-information includes an information of the probability for a predefined rule for simulating the change or growth of the specific object to occur.
