AUTOMATIC DOSE CONTROL FOR IMAGING MEDICAL DEVICES

摘要

The embodiments relate to a method, an analyzer, a radiation dose disturbance system, and a computer program for automatically calculating a target radiation dose of ionizing radiation. In this case, both patient-specific parameters and equipment-specific parameters are taken into account. On a cloud-based data store, reference images are read out that concern the same anatomical target region in which the imminent examination is also intended to be carried out. The anatomical target region is advantageously determined in a manner dependent on the clinical issue. The reference images are evaluated with regard to radiation dose and image quality in order to generate a target radiation dose with a corresponding control command.

1. A method for automatically calculating at least one target acquisition parameter to control a radiation dose of ionizing radiation of a region to be irradiated by an imaging device, the method comprising:
acquiring patient-specific parameters, device-specific parameters, or both the patient-specific parameters and the device-specific parameters; determining at least one anatomical target region in which the ionizing radiation is to be applied; accessing a data store via a network, wherein a dose-protocol index for a plurality of images is stored in the data store together with associated radiation dose data for selecting at least one reference image that relates to the at least one anatomical target region determined, approximately corresponds thereto, or completely encompasses the at least one anatomical target region; and automatically evaluating the at least one reference image selected with respect to the image quality and the radiation dose used taking into account the acquired patient-specific and/or device-specific parameters for calculating the at least one target acquisition parameter, wherein the evaluating of the image quality includes a delimitation algorithm in order to automatically analyze how adequately a respective anatomical structure is configured to be delimited from surrounding structures in the reference image.
