摘要：
The invention relates to a system (300) for performing and visualizing a measurement of an object viewed in an image computed from image data, the system comprising an image unit (310) for visualizing the image data in the image for displaying in a display, a deployment unit (320) for deploying a caliper (21 22 23 24) in an image data space based on the location of the object in the image data space, and a caliper unit (330) for visualizing the caliper (21 22 23 24) in the image, wherein the caliper (21 22 23 24) comprises a first planar surface (211) and a second planar surface (212) substantially parallel to the first planar surface (211), and wherein the measurement of the object is determined based on the distance between the planes of the first and second planar surface. Viewing the first and second planar surfaces of the caliper, visualized together with the measured object, improves the visualization of the measurement of an anatomical or pathological structure, because the first and second planar surface help a user to relate the measurement to the object—to see what is being measured. Advantageously, in an embodiment of the system (300), manually aligning the first and second planar surface with the object may also improve capturing the size of the object, because the system makes the measurement both easier to obtain and more accurate.
