+# XP.Scan 扫描配置文件设计文档
+
+## 1. 需求概述
+
+在平面CT扫描采集过程中，需要将当前扫描的所有参数信息（项目信息、射线源参数、探测器参数、运动控制参数、扫描配置、校正配置）打包为一个配置对象，最终序列化为 INI 格式文件传递给重构电脑。
+
+INI 文件结构与立式CT采集配置兼容，包含 6 个 Section：
+- `[Project_Information]` — 项目基本信息
+- `[XRay]` — 射线源参数
+- `[Detector]` — 探测器参数
+- `[Move_Control]` — 运动控制轴位置
+- `[Scan_Config]` — 扫描配置
+- `[Correction_Config]` — 校正参数
+
+## 2. 设计方案对比
+
+| 方案 | 优点 | 缺点 | 推荐 |
+|------|------|------|------|
+| A. 单个大类 `ScanConfig` | 简单直接 | 字段太多，职责不清 | ✗ |
+| B. 分组模型 + 序列化服务 | 职责清晰，可测试，可扩展 | 类稍多 | ✓ |
+| C. Dictionary + 手写序列化 | 灵活 | 无类型安全，易出错 | ✗ |
+
+**选择方案 B**：用分组模型类映射 INI 的每个 Section，加一个序列化服务负责读写 INI 文件。
+
+## 3. 数据模型设计
+
+### 3.1 整体结构
+
+```
+ScanConfigData (顶层聚合)
+├── ProjectInfo          → [Project_Information]
+├── XRayConfig           → [XRay]
+├── DetectorConfig       → [Detector]
+├── MoveControlConfig    → [Move_Control]
+├── ScanSettings         → [Scan_Config]
+└── CorrectionConfig     → [Correction_Config]
+```
+
+### 3.2 类定义
+
+```csharp
+namespace XP.Scan.Models

+
+```csharp

+
+    /// <summary>探测器旋转偏移 (°)</summary>
+    public double Detector_Rotation_Offset { get; set; }
+}
+```
+
+## 4. INI 序列化服务设计
+
+### 4.1 接口
+
+```csharp
+namespace XP.Scan.Services
+{
+    public interface IScanConfigSerializer
+    {
+        /// <summary>将配置数据序列化为 INI 格式字符串</summary>
+        string Serialize(ScanConfigData config);
+
+        /// <summary>将配置数据写入 INI 文件</summary>
+        void SaveToFile(ScanConfigData config, string filePath);
+
+        /// <summary>从 INI 文件读取配置数据</summary>
+        ScanConfigData LoadFromFile(string filePath);
+    }
+}
+```
+
+### 4.2 实现方案
+
+不引入第三方 INI 库，手写轻量级序列化，原因：
+- INI 结构简单固定（6 个 Section，字段已知）
+- 避免额外 NuGet 依赖
+- 完全可控，格式与立式CT兼容
+
+核心思路：用 `[IniSection("Section_Name")]` 和 `[IniKey("Key_Name")]` 特性标注模型属性，序列化时通过反射自动生成 INI 内容。
+
+### 4.3 特性定义
+
+```csharp
+/// <summary>标记 INI Section 名称</summary>
+[AttributeUsage(AttributeTargets.Class)]
+public class IniSectionAttribute : Attribute
+{
+    public string SectionName { get; }
+    public IniSectionAttribute(string sectionName) => SectionName = sectionName;
+}
+
+/// <summary>标记 INI Key 名称（可选，默认用属性名）</summary>
+[AttributeUsage(AttributeTargets.Property)]
+public class IniKeyAttribute : Attribute
+{
+    public string KeyName { get; }
+    public IniKeyAttribute(string keyName) => KeyName = keyName;
+}
+```
+
+### 4.4 模型标注示例
+
+```csharp
+[IniSection("Project_Information")]
+public class ProjectInfo
+{
+    [IniKey("fileSave")]
+    public string FileSave { get; set; } = string.Empty;
+
+    [IniKey("filter1")]
+    public string Filter1 { get; set; } = "None";
+
+    // ...
+}
+
+[IniSection("XRay")]
+public class XRayConfig
+{
+    [IniKey("Current_uA")]
+    public int Current_uA { get; set; }
+
+    // ...
+}
+```
+
+### 4.5 序列化输出示例
+
+```ini
+[Project_Information]
+fileSave=D:\HexagonCTData\Test_2026-04-21\Image
+filter1=Cu 0.2mm
+filter2=None
+Project=Test
+SampleNo=
+ScanMode=QuickScan
+
+[XRay]
+Current_uA=1000
+Focus=450um
+Voltage_kV=450
+
+[Detector]
+Det_Avg_Frames=1
+Det_Binning=1*1
+...
+```
+
+## 5. 文件结构规划
+
+```
+XP.Scan/
+├── Models/
+│   ├── ScanConfigData.cs          # 顶层聚合类
+│   ├── ProjectInfo.cs             # [Project_Information]
+│   ├── XRayConfig.cs              # [XRay]
+│   ├── DetectorConfig.cs          # [Detector]
+│   ├── MoveControlConfig.cs       # [Move_Control]

+│   └── IniKeyAttribute.cs         # Key 特性
+│
+├── Services/
+│   ├── IScanConfigSerializer.cs   # 序列化接口
+│   └── ScanConfigSerializer.cs    # 序列化实现（反射 + 手写 INI）
+│
+└── ...
+```
+
+## 6. 使用流程
+
+```
+1. 扫描开始前，从各硬件服务收集参数 → 填充 ScanConfigData
+
+   var config = new ScanConfigData();
+   config.XRay.Voltage_kV = raySourceService.CurrentVoltage;
+   config.XRay.Current_uA = raySourceService.CurrentCurrent;
+   config.Detector.Det_Avg_Frames = detectorService.AvgFrames;
+   config.MoveControl.X = motionService.GetPosition(AxisId.StageX);
+   config.ScanSettings.AcquiresNums = acquisitionCount;
+   // ...
+
+2. 序列化为 INI 文件
+
+   var serializer = new ScanConfigSerializer();
+   serializer.SaveToFile(config, @"D:\HexagonCTData\Test\ScanConfig.ini");
+
+3. 传递给重构电脑（文件拷贝或网络传输）
+```
+
+## 7. 设计决策
+
+| 决策 | 选择 | 理由 |
+|------|------|------|
+| 数据模型 | 分组类（每个 Section 一个类） | 职责清晰，属性有类型安全 |
+| 序列化方式 | 自定义特性 + 反射 | 轻量，无第三方依赖，格式完全可控 |
+| INI Key 映射 | `[IniKey]` 特性 | 属性名可以用 C# 命名规范，INI Key 保持与立式CT兼容 |
+| 数值格式 | `InvariantCulture` | 避免不同系统区域设置导致小数点格式不一致 |
+| 文件编码 | UTF-8 无 BOM | 兼容性最好 |
+
+## 8. 扩展性
+
+- 新增 Section：创建新模型类 + 标注 `[IniSection]` + 在 `ScanConfigData` 中添加属性
+- 新增字段：在对应模型类中添加属性 + 标注 `[IniKey]`
+- 反序列化：`LoadFromFile` 支持从 INI 文件回读配置（用于加载历史扫描参数）
+- 验证：可在模型类中添加 `Validate()` 方法，检查参数范围合法性
