Update summary
- Windows 2.2.0 users need a manual installation. Save your workspace and retain its source images before upgrading.
- Redesigned image-source dialog separates favorites and recent paths, with controls to remove one or all recent records.
- MTF accepts rectangular ROIs, shows actual sampling bounds, and computes only the 110% integration result, with simpler result details.
- Reopening the same series and view type activates its existing tab. Undo close is available from the tab bar.
- Image views support pinch zoom, with new shortcuts for opening views, annotations, export, and reset.
- Out-of-image ROIs use valid pixels for statistics. Improved drawing and labels; fixed confirmation keys and zoom-obscured highlight frames.
中文说明
升级须知
从 2.5.0 下载页选择对应平台安装包。Windows 2.2.0 用户仍需手动下载安装，该旧版本的更新器可能在开始安装前退出。
升级前保存工作区并保留副本，继续保留工作区引用的原始影像。已有自定义快捷键优先保留；若占用了新增的默认按键，新动作不会覆盖旧绑定，可在设置中重新分配。
已有 MTF 记录保留原数值与参数，不会自动重算。新计算采用更新后的取样规则，数值可能与旧版本不同；需要对比时请保留旧工作区副本，再主动重新计算。
主要改进
- 双指缩放：支持 2D、MPR、CPR、融合、对比、蒙太奇、3D 与 4D，无需切换当前工具。触屏以双指中心为锚点，触控板以鼠标所在视图中的位置为锚点；没有有效位置时使用视图中心。倍率范围为 0.1×–20×，已有缩放联动继续生效。
- 影像来源：扩大默认窗口，左侧分区显示收藏目录和最近打开，右侧浏览文件。最近记录支持单击打开、选中行末尾清除及删除全部；清除只影响记录，不删除文件或收藏。成功导入后记住最近 10 个来源和上次目录。
- MTF 取样：点源支持任意长宽的矩形选择框，由程序定位目标并确定积分和背景区域。可在影像上显示实际取样边界。日常加权 FFT 采用自适应基准的 110% 积分范围，不再重复执行 90% / 100% 对照；详情保留计算方式、取样尺寸、版本和时间。
- 快速打开视图：选中序列后，D 打开 2D、X 打开 MPR、T 打开 3D、Y 打开 CPR、O 打开蒙太奇、U 打开 4D、I 打开 DICOM 标签。右键菜单中的快捷键作用于右击的序列，仅允许打开该序列支持的视图。同一序列已存在同类页签时直接切换，保留其阅片状态。
- 常用操作按键：A 打开标注、E 打开导出、Q 整体重置当前视图；标注菜单中 A 选择箭头、T 选择文字。当前二级菜单优先处理自己的按键，退出后恢复通用按键；输入文字、打开弹窗或拖动时不会触发底层操作。
- 更清晰的测量反馈：长度、角度和 ROI 在满足最少有效点数及几何条件后显示指标。未选中的 ROI 显示名称和面积，选中后展开灰度统计；自动标签尽量避让轮廓、其他标签、方向文字和比例尺，仍可手动调整。
行为变化与问题修复
- MTF 改善目标定位、背景取样和积分范围确定，修复切换计算方式时未继续获取背景像素的问题。结果标签不再显示敏感性警告和来源分类；绘制新 MTF/FWHM 选区时，旧选区标签保持原有结果。
- “撤销关闭页签”入口从首页和工作区窗口移至页签栏右键菜单；关闭最后一页后仍可操作，Ctrl+Shift+T／⇧⌘T 保持有效。
- ROI 部分超出有效影像范围时，平均值、标准差、最小值、最大值和像素数只依据有效像素计算；绘制面积和尺寸不裁减。完全没有有效像素时明确提示，不显示伪造的灰度数值。
- Q 沿用“全部重置”的行为，包括清除当前视图相应的测量和标注；需要保留结果时请先保存工作区。当前工具的局部重置仍使用 R。CPR 整体重置补齐图像显示状态的恢复，不删除已有路径。
- 修复切换页签或关闭工作区弹窗后，曲线与 CPR 的 Enter / Esc 不能确认或取消绘制的问题。
- 修复开始拖动时丢失第一段位移，改善平移和测量编辑的跟手反馈。
- 修复 CPR 绘制新路径时结果状态文字重复、窗模板命名时 Esc 无法取消，以及伪彩影响影像外留白的问题。
- 修复蒙太奇缩放、平移后悬停边框被影像覆盖，以及底部边框偶发裁切。
安装兼容性与已知限制
- macOS：Apple Silicon DMG，ad-hoc 签名，未经 Apple 公证。
- Windows：x64 安装版及单文件便携版，未配置 Authenticode 签名。
- 手势识别依赖操作系统和设备提供的触控事件；自动化事件验证不等于所有实体触控屏和触控板均完成验收。
- 标签空间不足时仍可能重叠，可手动移动。CPR 仍为手动路径，不提供自动血管追踪。
- MTF 的 110% 是内部自适应积分范围系数，不是选区尺寸或背景取样范围的比例，也不保证比其他系数更准确。曲面背景、弱尾部及噪声仍会影响结果；未做有限目标尺寸修正，不自动判定合格。
- 未在干净物理 Windows 设备或另一台 Mac 上完成人工安装及阅片验收；具体完成与未覆盖范围见发布验收记录。

Released 2026-11-10. Easier image import and tab navigation, with improved MTF sampling and measurement feedback.
Upgrade notes
Choose your platform package from the 2.5.0 release. Windows 2.2.0 users still need a manual installation because that older updater may exit before installation begins.
Save a copy of your workspace before upgrading and retain its source images. Existing custom shortcuts take priority: a new action will not overwrite an occupied binding. Reassign it in Settings if needed.
Existing MTF records retain their values and parameters without automatic recalculation. New calculations use revised sampling rules and may differ from older versions. Keep an old workspace copy before recalculating for comparison.
Improvements
- Pinch zoom: Supported in 2D, MPR, CPR, fusion, comparison, montage, 3D, and 4D views without switching tools. Touchscreens use the finger midpoint; trackpads use the pointer position in the viewport, falling back to the viewport center when unavailable. The range is 0.1×–20×, and existing zoom links remain effective.
- Image sources: A wider dialog separates favorites and recent paths on the left from file browsing on the right. Open recent sources with one click, remove the selected record, or clear all history. Source files and favorites remain intact. Successful imports retain the last 10 sources and the last directory.
- MTF sampling: Rectangular selections locate a point target; the application determines integration and background regions and can overlay their actual bounds. Weighted FFT calculations use 110% of the adaptive integration baseline without repeated 90% / 100% comparisons. Details retain the method, sampling dimensions, version, and time.
- Open views quickly: With a series selected, D opens 2D, X MPR, T 3D, Y CPR, O montage, U 4D, and I DICOM tags. Context-menu shortcuts target the right-clicked series. Supported views reuse an existing tab for the same series and view type, preserving its reading state.
- Common actions: A opens annotations, E export, and Q resets the current view. Within annotations, A selects arrows and T text. Active tool menus take priority over general bindings; dialogs, text entry, and dragging isolate their input.
- Measurement feedback: Metrics appear after enough valid points and geometry are available. Unselected ROIs show compact name-and-area labels; selection expands intensity statistics. Automatic placement avoids nearby shapes, labels, orientation text, and scale bars when space permits, with manual adjustment available.
Behavior changes and fixes
- Improved MTF target localization, background sampling, and integration bounds; fixed missing background-context sampling after a calculation-method change. Result labels omit sensitivity warnings and source categories. Drawing a new MTF/FWHM ROI keeps previous ROI labels unchanged.
- Undo close moved from the home screen and workspace dialog to the tab-bar context menu, including when no tabs remain. Ctrl+Shift+T / ⇧⌘T remains available.
- Partially out-of-image ROIs calculate mean, standard deviation, minimum, maximum, and pixel count from valid pixels only. Drawn area and dimensions remain unchanged. Empty intersections explicitly report no valid pixels.
- Q retains the existing Reset all behavior, including clearing the corresponding measurements and annotations in the current view. Save results first. R remains the local tool reset. CPR now restores image display state through the shared reset action while retaining its paths.
- Fixed Enter / Esc failing to finish or cancel curve and CPR drawing after switching tabs or closing workspace dialogs.
- Fixed lost initial drag movement when panning or editing measurements.
- Fixed duplicate CPR result-status labels during new-path drawing, Esc failing to cancel window-preset naming, and pseudocolor tinting the canvas outside the image.
- Fixed montage hover frames being covered by zoomed or panned images and occasional clipping of their bottom edge.
Installation, compatibility, and known limitations
- macOS: Apple Silicon DMG with ad-hoc signing, without Apple notarization.
- Windows: x64 installer and single-file portable EXE, without Authenticode signing.
- Gesture availability depends on events supplied by the operating system and device. Automated event checks do not certify every physical touchscreen or trackpad.
- Dense labels may still overlap and can be moved manually. CPR uses manually drawn paths, without automatic vessel tracking.
- MTF's 110% scales an internal adaptive integration baseline, not the selection or background region. It does not guarantee greater accuracy. Curved backgrounds, weak tails, and noise still affect results; finite target size is not corrected and results are not automatically graded.
- Manual installation and reading workflows on a clean physical Windows device or another Mac remain unverified. See the acceptance record for completed checks and remaining limits.
