0. Extension
Definition	Die Extension ermöglicht es, Informationen zur ausgewählten Serie auf Instanz-Ebene anzugeben. Optional Extension Element - found in all resources.
Short	MII EX Bildgebung InstanzdetailsOptional Extensions Element
Control	0..* This element is affected by the following invariants: ele-1
Is Modifier	false
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
2. Extension.extension:pixelSpacingX
Slice Name	pixelSpacingX
Definition	An Extension
Short	ExtensionAdditional content defined by implementations
Control	0..1*
Type	Extension
Is Modifier	false

Summary	false
Invariants	ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
4. Extension.extension:pixelSpacingX.extension
Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element. 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.
Short	ExtensionAdditional content defined by implementations
Comments	There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
