DICOM_Attribute_Sequence

Due to the recursive nature of DICOM structures, you need a "reference" structure. The "root" structure must always be "reset" before you start digging in the DICOM tags.

Syntax

DICOM_Attribute_Sequence_Reset(

HWND hwnd,

DICOM_Root *local_root

) ;

Parameters

hwnd

Current Window. (Note: You can use the "hwnd" external variable, so you don't have to search very far to find it.)

local_root

Pointer to a DICOM_Root structure.

Return value

This function

// Function: Get_Frame_Of_Reference_UID

// Parameters: frame (SliceO_Frame *)

// Returns: (char *)

// fetch this frame's "Frame of Reference UID" tag (0020,00052)

...

// --- get the frame's header ---

Tomo_Image *header = (Tomo_Image *) frame->m_ima ;

// --- Get the FoR from the image's header ---

DICOM_List *tag_FoR_UID = DICOM_Attribute_Get( hwnd, &local_root, header->DICOM_org, 0x0020, 0x0052 ) ;

if ( tag_FoR_UID ) {

char **str = NEMA_Value_Str( hwnd, tag_FoR_UID ) ;

if ( str )
