A medical data processing method for supporting determination of medical image data describing a spatial distribution of body tissue which is the subject of a medical procedure, the method comprising the following steps which are constituted to be executed by a computer: a) acquiring outcome atlas data describing a general probability that a specific anatomical structure can be treated successfully by means of the medical procedure, the general probability having been determined based on a statistical analysis of medical image data and/or treatment effect simulations conducted on said medical image data generated from a general population of human bodies; b) acquiring general population data describing at least one statistical feature of each member of the general population, wherein the at least one statistical feature of a patient can be compared to the at least one statistical feature of each member of the general population; c) acquiring patient definition data describing at least one statistical feature of a patient who shall become the subject of the medical procedure, wherein the at least one statistical feature of each member of the general population and the at least one statistical feature of the patient pertain to at least one of genetic information and information about the gender, age, ethnicity, mass and pathological state of the members of the general population and the patient, respectively; d) determining, based on the outcome atlas data and the general population data and the patient definition data, adapted population data describing an adapted population of human bodies taken from the general population, wherein the adapted population data is determined by comparing the value of the at least one statistical feature of the patient to the value of the at least one statistical feature of each member of the general population and wherein members of the general population which have a predetermined similarity to the patient are determined as the members of the adapted population and on the basis of the result of the comparison of the values of the at least one statistical feature, wherein the adapted population is to be used as a basis for generating adapted outcome atlas data describing an adapted probability that the specific anatomical structure can be treated successfully by means of the medical procedure, which adapted probability is determined based on the adapted population. a) acquiring outcome atlas data describing a general probability that a specific anatomical structure can be treated successfully by means of the medical procedure, the general probability having been determined based on a statistical analysis of medical image data and/or treatment effect simulations conducted on said medical image data generated from a general population of human bodies; b) acquiring general population data describing at least one statistical feature of each member of the general population, wherein the at least one statistical feature of a patient can be compared to the at least one statistical feature of each member of the general population; c) acquiring patient definition data describing at least one statistical feature of a patient who shall become the subject of the medical procedure, wherein the at least one statistical feature of each member of the general population and the at least one statistical feature of the patient pertain to at least one of genetic information and information about the gender, age, ethnicity, mass and pathological state of the members of the general population and the patient, respectively; d) determining, based on the outcome atlas data and the general population data and the patient definition data, adapted population data describing an adapted population of human bodies taken from the general population, wherein the adapted population data is determined by comparing the value of the at least one statistical feature of the patient to the value of the at least one statistical feature of each member of the general population and wherein members of the general population which have a predetermined similarity to the patient are determined as the members of the adapted population and on the basis of the result of the comparison of the values of the at least one statistical feature, wherein the adapted population is to be used as a basis for generating adapted outcome atlas data describing an adapted probability that the specific anatomical structure can be treated successfully by means of the medical procedure, which adapted probability is determined based on the adapted population.
