How dicom-parser.js works with vtk.js to achieve dicom file display about dicomparser HOT 4 CLOSED

thank you for your reply I modified the code, the pixel data of the dicom file should be passed this time, but nothing is displayed after running, is it my mistake? I just got rid of medical imaging, and I am still not familiar with it, please guide me test () { axios.get('src/views/modules/generator/demo.dcm', { responseType: 'arraybuffer' }).then(response => { this.render3DModel(response.data) }).catch(error => { console.error(error) }) }, render3DModel (dicomData) { const byteArray = new Uint8Array(dicomData) const dataSet = DICOMParser.parseDicom(byteArray) const pixelDataElement = dataSet.elements.x7fe00010 const pixelData = new Int16Array(dataSet.byteArray.buffer, pixelDataElement.dataOffset, pixelDataElement.length / 2) const rows = dataSet.uint16('x00280010') || 1 const columns = dataSet.uint16('x00280011') || 1 const slices = dataSet.uint16('x00540081') || 1 const pixelSpacingX = dataSet.floatString('x00280030', 0) || 1 const pixelSpacingY = dataSet.floatString('x00280030', 1) || 1 const sliceSpacing = dataSet.floatString('x00180088') || 0 console.log("Rows:", rows); console.log("Columns:", columns); console.log("Slices:", slices); console.log("Pixel Spacing X:", pixelSpacingX); console.log("Pixel Spacing Y:", pixelSpacingY); console.log("Slice Spacing:", sliceSpacing); const dataArray = vtkDataArray.newInstance({ numberOfComponents: 1, values: Array.from(pixelData), dataType: 'Int16Array', name: 'scalars' }) const imageData = vtkImageData.newInstance() imageData.setDimensions(rows, columns, slices) imageData.setSpacing(pixelSpacingX, pixelSpacingY, sliceSpacing) imageData.getPointData().setScalars(dataArray) const volumeMapper = vtkVolumeMapper.newInstance() volumeMapper.setInputData(imageData) const volume = vtkVolume.newInstance() volume.setMapper(volumeMapper) const container = document.getElementById('vtk-container') const fullScreenRenderer = vtkFullScreenRenderWindow.newInstance({ container: container, background: [1, 1, 1] }) try { fullScreenRenderer.getRenderer().addVolume(volume) fullScreenRenderer.getRenderer().resetCamera() fullScreenRenderer.getRenderer().resetCameraClippingRange() fullScreenRenderer.getRenderWindow().render() } catch (error) { console.error('erro：', error) } finally { console.log('end') } },
