在Java项目中处理DICOM图像,通常可以使用开源库,如dcm4che2或PixelMed
- 添加依赖:首先,需要在项目中添加dcm4che2的依赖。如果你使用Maven,可以在pom.xml文件中添加以下依赖:
<groupId>org.dcm4che</groupId> <artifactId>dcm4che-core</artifactId> <version>5.23.0</version> </dependency><dependency> <groupId>org.dcm4che</groupId> <artifactId>dcm4che-imageio</artifactId> <version>5.23.0</version> </dependency>
- 读取DICOM文件:使用dcm4che2库读取DICOM文件并获取其中的图像数据。以下是一个简单的示例:
import org.dcm4che3.data.Attributes; import org.dcm4che3.data.Tag; import org.dcm4che3.io.DicomInputStream; import org.dcm4che3.io.DicomOutputStream; import java.io.File; import java.io.IOException; public class DicomReader { public static void main(String[] args) { File dicomFile = new File("path/to/your/dicom/file.dcm"); try (DicomInputStream dis = new DicomInputStream(dicomFile)) { Attributes attributes = dis.readDataset(-1, -1); String patientName = attributes.getString(Tag.PatientName, "Unknown"); System.out.println("Patient Name: " + patientName); } catch (IOException e) { e.printStackTrace(); } } }
- 将DICOM图像转换为Java图像:使用dcm4che2的ImageIO插件将DICOM图像转换为Java BufferedImage。以下是一个简单的示例:
import org.dcm4che3.imageio.plugins.dcm.DicomImageReadParam; import org.dcm4che3.io.DicomInputStream; import javax.imageio.ImageIO; import javax.imageio.ImageReadParam; import javax.imageio.ImageReader; import javax.imageio.stream.ImageInputStream; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; public class DicomToImage { public static void main(String[] args) { File dicomFile = new File("path/to/your/dicom/file.dcm"); try (ImageInputStream iis = ImageIO.createImageInputStream(dicomFile)) { ImageReader reader = ImageIO.getImageReadersByFormatName("DICOM").next(); reader.setInput(iis, false); ImageReadParam param = new DicomImageReadParam(); BufferedImage image = reader.read(0, param); // 现在可以对image进行处理,例如缩放、旋转等 } catch (IOException e) { e.printStackTrace(); } } }
- 保存Java图像:最后,可以将处理后的Java图像保存到文件中。以下是一个简单的示例:
import javax.imageio.ImageIO; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; public class SaveImage { public static void main(String[] args) { BufferedImage image = ...; // 从上面的示例中获取处理后的图像 File outputFile = new File("path/to/output/image.png"); try { ImageIO.write(image, "png", outputFile); } catch (IOException e) { e.printStackTrace(); } } }
这些示例展示了如何在Java项目中使用dcm4che2库处理DICOM图像。你可以根据自己的需求对这些示例进行修改和扩展。
