C.1 Class and Profile Identification

This Annex defines Application Profiles for Ultrasound Media Storage applications. Each Application Profile has a unique identifier used for conformance claims. Due to the variety of clinical applications of storage media in Ultrasound, a family of application profiles are described in this section to best tailor an application choice to the specific needs of the user. The identifier used to describe each profile is broken down into three parts: a prefix, mid-section, and suffix. The prefix describes the overall Application Profile Class and is common for all ultrasound application profiles. The mid section describes the specific clinical application of the profile. The suffix is used to describe the actual media choice the profile will use.

The prefix for this class of application profiles is identified with the STD-US identifier.

Note: Conformance Statements may use the earlier prefix of APL which is equivalent to STD. This use is deprecated and may be retired in future versions of the standard.

The midsection is broken down into three subclasses which describes the clinical use of the data. These classes are: Image Display (ID identifier), Spatial Calibration (SC identifier), and Combined Calibration (CC identifier). All three subclasses can be applied to either single frames (SF) images or single and multi-frames (MF) images. The SC subclass enhances the ID class by adding the requirement for region specific spatial calibration data with each IOD. The CC subclass enhances the SC subclass by requiring region specific pixel component calibration.

The suffix, xxxx, is used to describe the actual media choice used for the conformance claim. Any of the above mentioned classes can be stored onto one of eight pieces of media described in the Table C.3-3.

The specific Application Profiles are shown in the following table.

Table C.1-1ULTRASOUND APPLICATION PROFILE IDENTIFIERS

Application Profile Single Frame Single & Multi-Frame
Image Display STD-US-ID-SF-xxxx STD-US-ID-MF-xxxx
Spatial Calibration STD-US-SC-SF-xxxx STD-US-SC-MF-xxxx
Combined Calibration STD-US-CC-SF-xxxx STD-US-CC-MF-xxxx

The ID Application Profile Classes are intended to be used for the transfer of ultrasound images for display purposes.

The SC Application Profile Classes are intended to be used for the transfer of ultrasound images with spatial calibration data for quantitative purposes (see section C.4).

The CC Application Profile Classes are intended to be used for the transfer of ultrasound images with spatial and pixel component calibration data for more advanced quantitative purposes (see section C.5).
