A computer-implemented method is for providing cross-linking between cloud-based web-applications. A consumer web-application calls a Uniform Resource Locator, URL, implemented in a customized provider webpage of a provider web-application to activate the customized provider webpage of the provider web-application via a cross link, the URL, including an URL extension with additional URL parameters to provide autonavigation to a customized specific internal view of the activated provider webpage. The customized specific internal view of the activated provider webpage is opened automatically on top of the calling web-application until the activated provider webpage is closed in response to a corresponding user command input via a user interface. The last state and context of the calling consumer web-application is kept and is used to restore automatically the original calling consumer web-application after the provider webpage of the provider web-application is closed.

Method and system for managing and editing data of a medical device

A device transmits a request to access image data stored in a cloud and then receives an access path to the image data. If the image data are in a first data format, the device reads the image data via the access path, converts them into the second data format, and stores the converted image data in the cloud. It also modifies the access path according to a modification rule and stores the modified access path in the cloud. If the image data are in the second data format, the device either always reads the image data in the second data format via the access path or checks whether a special instruction has been defined. On the basis of the special instruction, the device either reads the image data in the second data format via the access path or remodifies the access path using the modification rule.

Efficient method for accessing image data stored in a cloud

Measurement results are acquired by a number of medical imaging systems in each case using a respective measurement protocol and by applying a respective dose. Data records are automatically placed in a cloud by the systems or a PACS connected to the respective system. Measurement protocols, applied doses, and anonymized images of the data records are referenced among each other. The data records placed in the cloud are assigned the respective examination type and an identification of the respective system and/or an identification of the type of respective system. The cloud accepts data queries from users. The data queries as a search criterion specify at least the examination type, the identification of the respective system, and/or the identification of the type of the respective system. The data records are determined by the cloud in accordance with the respective data query and are made available to the respective user.

In a method, a topogram of an examination volume is received via an interface. A water equivalent diameter (abbreviated to WED) of a slice plane of the examination volume is then determined, via a computer unit, based on the topogram. Thereafter, via the computer unit, a noise level is determined based on the WED, the noise level being an upper threshold value for noise of a CT image dataset. Finally, via the computer unit, a reference dose parameter is determined, based on the noise level determined and the WED, the reference dose parameter corresponding to a first x ray dose, absorbable in the slice plane during a recording of a first CT image dataset of the examination volume upon noise of the first CT image dataset corresponding to the noise level determined.

In a method, a personal dose report image is received via a first interface. The personal dose report image includes personal data and dose data of an imaging by way of ionizing radiation. The personal data and the dose data are contained as rasterized text in the personal dose report image and the personal data or the dose data includes a first signal word. A first position of the first signal word in the personal dose report image is determined through optical character recognition. An image area in the personal dose report image is determined based on the first position, the image area including at least a part of the personal data. An anonymized dose report image based on the personal dose report image is determined, at least the image area of the anonymized dose report image corresponding to the image area of the personal dose report image being anonymized.

The present disclosure relates to methods for automatically controlling loading processes of dose information images. In one example, the method includes receiving a data record at a local data repository, wherein the data record contains a dose information image and a scanner index. The method further includes: comparing the scanner index against a whitelist from the central data repository; transmitting the data record from the local data repository to a checking directory of the central data repository when the scanner index is not contained in the whitelist; validating the dose information image from the checking directory by character recognition; and entering the scanner index in the whitelist in the event of successful validation of the dose information image.

Method for processing dose information images

In a method, a water equivalent diameter (abbreviated to WED) of a slice plane of an examination volume is received via an interface. In an embodiment, a noise level based on the water equivalent diameter is determined via a computer unit, the noise level being an upper threshold value for the noise of a CT image dataset. Furthermore a reference dose parameter is determined based on the noise level and the water equivalent diameter via the computer unit, the reference dose parameter corresponding to a first x-ray dose, which would be absorbed in the slice plane during a recording of a first CT image dataset of the examination volume upon the noise of the first CT image dataset corresponding to the noise level. Finally, the reference dose parameter is indirectly proportional to a power of the noise level.

In at least one embodiment, X-ray images of a human examination object acquired via X-ray equipment are each spatially-resolved in a plurality of dimensions. In each case, one dimension extends in the head-foot direction of the examination object. The respective body region is detected in the X-ray images in steps that are equidistant in the head-foot direction and, based on this, the water-equivalent diameter of the examination object is determined in a plane orthogonal to the head-foot direction. The water equivalent diameters determined for each respective position is stored with allocation to the X-ray images and the respective position in the head-foot direction.
