It covers accessing file content, decoding pixel data, retrieving attributes by tag or name, and accessing pixel data properties. This functionality is crucial for any DICOM data processing. ```objective-c // Read a DICOM file with pixel data NSString *path = @"/path/to/dicom/file.dcm"; DCMObject *dcmObject = [DCMObject objectWithContentsOfFile:path decodingPixelData:YES]; // Access DICOM attributes by tag DCMAttributeTag *nameTag = [DCMAttributeTag tagWithName:@"PatientsName"]; DCMAttribute *nameAttr = [dcmObject attributeForTag:nameTag]; NSString *patientName = [[nameAttr values] objectAtIndex:0]; // Access attributes by name directly NSString *studyDesc = [dcmObject attributeValueWithName:@"StudyDescription"]; NSString *studyUID = [dcmObject attributeValueWithName:@"StudyInstanceUID"]; // Access pixel data DCMPixelDataAttribute *pixelData = [dcmObject attributeForTag: [DCMAttributeTag tagWithName:@"PixelData"]]; NSLog(@"Dimensions: %d x %d", [pixelData rows], [pixelData columns]); ``` -------------------------------- ### JavaScript Share Destination Change Handler Source: https://github.com/bettar/miele-lxiv/blob/lxiv/Binaries/WebServicesHTML/English/study.html This function `shareDestinationChange` controls the visibility of an element with the ID 'shareDestinationCreateTemp'. It toggles the display style of this element based on the selected value of a dropdown menu, showing it only when the selected value is 'NEW'. ```javascript function shareDestinationChange(select) { document.getElementById('shareDestinationCreateTemp').style.display = select.options[select.selectedIndex].value == 'NEW'? 'inline' : 'none'; } ``` -------------------------------- ### DICOM C-MOVE Retrieve Studies using Objective-C Source: https://context7.com/bettar/miele-lxiv/llms.txt This snippet illustrates how to initiate a DICOM C-MOVE operation to retrieve a specific study from a remote PACS server. It involves creating a move request object specifying the Study Instance UID and Query/Retrieve Level, along with connection parameters and the destination AET for the retrieved files. The operation returns a boolean indicating success. ```objective-c // Create move request for specific study DCMObject *moveObject = [DCMObject dcmObject]; [moveObject setAttributeValues:[NSMutableArray arrayWithObject: "1.2.840.113619.2.55.3.12345678.987"] forKey:@"StudyInstanceUID"]; [moveObject setAttributeValues:[NSMutableArray arrayWithObject:@"STUDY"] forKey:@"Query/RetrieveLevel"]; // Configure connection and move destination NSMutableDictionary *params = [NSMutableDictionary dictionary]; [params setObject:@"MIELE_LXIV" forKey:@"callingAET"]; [params setObject:@"REMOTE_PACS" forKey:@"calledAET"]; [params setObject:@"192.168.1.100" forKey:@"hostname"]; [params setObject:@"11112" forKey:@"port"]; [params setObject:@"MIELE_LXIV" forKey:@"moveDestination"]; [params setObject:moveObject forKey:@"moveObject"]; [params setObject:[DCMAbstractSyntaxUID studyRootQueryRetrieveInformationModelMove] forKey:@"affectedSOPClassUID"]; [params setObject:[DCMTransferSyntax ExplicitVRLittleEndianTransferSyntax] forKey:@"transferSyntax"]; // Execute move - PACS will send files to moveDestination AET BOOL success = [DCMMoveSCU moveWithParameters:params]; if (success) { NSLog(@"Move request completed successfully"); } ``` -------------------------------- ### JavaScript Form Checkbox Control Functions Source: https://github.com/bettar/miele-lxiv/blob/lxiv/Binaries/WebServicesHTML/English/study.html Contains JavaScript functions to control checkboxes within a form. `checkAll` and `uncheckAll` toggle the state of all checkboxes, while `checkboxChanged` updates the enabled/disabled state of 'CheckAll' and 'UncheckAll' buttons based on the selection status. It also manages the state of elements with the class 'if_selection'. ```javascript function checkAll(form) { for (var i = 0; i < form.selected.length; i++) form.selected[i].checked = true; checkboxChanged(form); } function uncheckAll(form) { for (var i = 0; i < form.selected.length; i++) form.selected[i].checked = false; checkboxChanged(form); } function checkboxChanged(form) { var allChecked = true; var allUnchecked = true; if( form.selected) { for (var i = 0; i < form.selected.length; i++) { if (allChecked && !form.selected[i].checked) allChecked = false; if (allUnchecked && form.selected[i].checked) allUnchecked = false; } } if( form.CheckAll) form.CheckAll.disabled = allChecked; if( form.UncheckAll) form.UncheckAll.disabled = allUnchecked; var ifs = form.getElementsByClassName('if_selection'); for (var i = 0; i < ifs.length; ++i) { ifs[i].disabled = allUnchecked; if (ifs[i].classList) { if (ifs[i].disabled && !ifs[i].classList.contains('disabled')) ifs[i].classList.add('disabled'); if (!ifs[i].disabled && ifs[i].classList.contains('disabled')) ifs[i].classList.remove('disabled'); } } } ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
