Extension Modalität Mammografie, Röntgen, Digitales Röntgen

Die Extension für die Modalitäten MG (Mammographie), CR (Computed Radiography) und DX (Digital Radiography) ermöglicht das Erfassen relevanter DICOM-Tags, um Rückschlüsse über die Bildgewinnung ziehen zu können. Diese Modalitäten nutzen Röntgenstrahlen zur Erstellung von Bildern des Körpers, wobei die Strahlungserzeugung, Strahlenbelastung und spezifischen technischen Parameter der Bildgebung in den entsprechenden DICOM-Tags festgehalten werden.

Relevante DICOM-Tags:

Röntgenröhrenspannung [(0018, 0060) KVP] in Kilovolt [kV]
Expositionszeit [(0018, 1150) exposureTime] in Millisekunden [ms]
Exposition [(0018, 1152) exposure] in Milliampere-Sekunden [mAs]
Röntgenröhrenstrom [(0018, 1151) xRayTubeCurrent] in Milliampere [mA]
Blickposition [(0018,5101)] kann für MG- bzw. Röntgen-Aufnahmen über die von DICOM bereitgestellten Mappings in SNOMED CT überführt werden.

To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

value	Σ	0..1	decimal	There are no (further) constraints on this element Element id Extension.extension:xRayTubeCurrent.value[x].value Short description Numerical value (with implicit precision) Definition The value of the measured amount. The value includes an implicit precision in the presentation of the value. Requirements Precision is handled implicitly in almost all cases of measurement. Comments The implicit precision in the value should always be honored. Monetary values have their own rules for handling precision (refer to standard accounting text books).

comparator	Σ ?!	0..0	codeBinding	There are no (further) constraints on this element Element id Extension.extension:xRayTubeCurrent.value[x].comparator Short description < \| <= \| >= \| > - how to understand the value Definition Not allowed to be used in this context Requirements Need a framework for handling measures where the value is <5ug/L or >400mg/L due to the limitations of measuring methodology. Comments Note that FHIR strings SHALL NOT exceed 1MB in size Meaning when missing If there is no comparator, then there is no modification of the value Data type code Binding How the Quantity should be understood and represented.

code	Σ	0..1	codePattern	Element id Extension.extension:xRayTubeCurrent.value[x].code Short description Coded form of the unit Definition A computer processable form of the unit in some unit representation system. Requirements Need a computable form of the unit that is fixed across all forms. UCUM provides this for quantities, but SNOMED CT provides many units of interest. Comments The preferred system is UCUM, but SNOMED CT can also be used (for customary units) or ISO 4217 for currency. The context of use may additionally require a code from a particular system.

Hinweis
	Aus Gründen der Übersichtlichkeit wurde in diesem Beispiel darauf verzichtet, alle dazugehörigen Serien bzw. Instanzen mit einzubinden. Natürlich ist es bei der Implkementierung vorgesehen, dass alle zur jeweiligen Studie gehörenden Serien und Instanzen auch in der resultierenden FHIR-Ressource enthalten sind - dafür wird dann einfach die Sequenz "series" bzw "instance" für jede Serie bzw. Instanz wiederholt und mit den entsprechenden Werten befüllt.
