Problems solved by technology

[0005] However, these measurements according to the prior art are static and it is not possible to interact with these measurements except in some cases for moving the position of the measurement marker
When measuring angles with two lines, it is difficult to control which angle is desired, i.e. it is difficult to control in which of the four quadrants the user wants to place the angle measurement
Furthermore, for a typical user of a medical examination workstation, such as a doctor, it has so far not been possible to add measurements to already existing graphic objects
So when the measurement is not satisfactory, it has to be repeated as above, or it does not achieve some desired measurement at all

Embodiment Construction

[0028] figure 1 An exemplary medical imaging system 1 is shown with respect to one or more conventional imaging techniques, such as CT, MRI or others. Said system 1 comprises at least one image monitor 10 , keyboard 11 , mouse 12 and processor equipped with appropriate memory 13 . All these subsystems are interconnected by suitable interconnection devices 14, which can be bus based. I / O device 15 is interconnected to the outside world for receiving image data obtained from a detection subsystem (not shown for simplicity) and for outputting processed image data for long-term storage, hard copy and others. The user personnel can manipulate the medical images displayed on the monitor 10 in various ways, eg by mouse and / or keyboard actuation as described in NL031038 and US-A-20020067340. Various other system configurations will be apparent to those skilled in the art of graphics operating systems.

[0029] In the following, the current embodiment of the method according to the ...

Abstract

In a medical imaging system the flexibility and power of measurement tools is improved by making the measurements objects themselves, whereby flexible interaction is provided. The measurement objects(52) are aware of their position relative to other graphical objects (50, 51) in the image. A user of a medical imaging system is thus enabled to easily perform desired measurements and to display theresults thereof in a reliable and flexible manner. A method, an apparatus and a computer-readable medium are provided for processing cursored user interaction with a spatially displayed medical imagefor producing graphics related measurement data on the medical image. The medical image comprises at least one graphics object and dynamic measurement objects are attached to said graphics object, wherein the measurement object may be moved, removed or transferred to other graphic objects on the medical image at any time.

Description

technical field [0001] The present invention relates generally to the field of image-related measurements, more particularly to the measurement of parameters in medical images, and still more particularly to the measurement of geometric parameters such as lengths and angles associated with objects imaged on medical images Measurement. Background technique [0002] Medical workstations and applications provide several standard measurement tools for measuring distances (eg, length or diameter) and for measuring angles. For example, specialists in the field of orthopedics use medical software packages to measure physical properties of the skeletal system, such as the length of bones and the angles between bone axes. [0003] Distance is measured by drawing a line on the image, where the line is drawn between two points. Markers near the line then show the distance. Angles are measured by drawing two lines with the aid of three or four points on the image. The markers show t...
