Access data in a DICOM data object.
DICOM is a widely used file format for storing medical image data (CT, MRI, etc), defined by the National Electrical Manufacturers Association (NEMA) (http://dicom.nema.org).
This class, along with SoDicomTag, SiDicomElement, SiDicomValue and SiDicomSequence, allows an application to iterate over or randomly access all the attributes in a DICOM data object. This includes attributes that are not used by VolumeViz for rendering.
This class cannot directly open a DICOM file. An SiDicomDataSet object can be requested from an SoVRDicomFileReader object or an SoVRDicomData object using the getDicomDataSet() method.

pure virtual |
Create a clone of the current data set.
|
pure virtual |
Get the n-th element of this data set.
idx | the index of the element in the data set. |
|
pure virtual |
Get an element of this data set.
tag | the tag of the element to find. |
|
pure virtual |
Shortcut to extract an element's buffer value.
tag | The tag of the element to find. |
buffer | The buffer to fill with element's value. |
|
pure virtual |
Shortcut to extract a DOUBLE element's value.
If the value is of a numeric type different from DOUBLE, it will be casted to a double. That casting may cause a precision loss.
tag | The tag of the element to find. |
idx | The index of the scalar value to extract. |
defaultValue | The value returned if the extraction fails. |
|
pure virtual |
Shortcut to extract a INT element's value.
If the value is of a numeric type different from INT, it will be casted to a 64 bits integer. That casting may cause a precision loss.
tag | The tag of the element to find. |
idx | The index of the scalar value to extract. |
defaultValue | The value returned if the extraction fails. |
|
pure virtual |
Shortcut to extract a STRING element's value.
If the stored value if not of type STRING, this method will return a string representation of the value. currently works for INT, UINT, and DOUBLE.
tag | The tag of the element to find. |
idx | The index of the scalar value to extract. |
defaultValue | The value returned if the extraction fails. |
|
pure virtual |
Shortcut to extract a UINT element's value.
If the value is of a numeric type different from UINT, it will be casted to an unsigned 64 bits integer. That casting may cause a precision loss.
tag | The tag of the element to find. |
idx | The index of the scalar value to extract. |
defaultValue | The value returned if the extraction fails. |
