Benefits of technology

[0014] According to the present invention, the at least one first measurement reference element corresponding to the at least one second measurement reference element on the measurement reference image can be automatically set on the object image without the user's manipulation. Therefore, the automatic measurement of the geometric feature of the object image can be efficiently made.
[0038] (viii) The measurement processing apparatus according to the present invention may further comprise a display unit which allows the user to confirm the at least one first position of the at least one first measurement reference element which is automatically set on the object image, and a measurement-reference-element modification unit which facilitates modification of the at least one first position of the at least one first measurement reference element by the user. In this case, when the user determines that the at least one first position of the at least one first measurement reference element which is automatically set on the object image is not appropriate, the user can modify the at least one first position of the at least one first measurement reference element. The measurement-reference-element modification unit may comprise a pointing device such as a mouse.

Problems solved by technology

Therefore, conventionally, the efficiency of measurement of a geometric feature of an image and diagnosis based on the measurement is low.

Advantages of Embodiment

[0095] As explained above, the radiographic-image measurement apparatus 1 as an embodiment of the present invention can automatically set at least one measurement reference element (e.g., a plurality of measurement reference points) on an object image Q1 in an appropriate order so that the at least one measurement reference element (e.g., the plurality of measurement reference points) on an object image Q1 corresponds to at least one previously-set measurement reference element (e.g., a plurality of previously-set measurement reference points) which has been set on a previously-measured image Q2. Therefore, it is possible to efficiently make automatic measurement of a geometric feature (quantity) of the object image Q1.

[0096] In addition, the previously-measured image Q2 is displayed in the vicinity of the object image Q1, and at least one previously-set measurement reference element (e.g., a plurality of previously-set measurement reference points) are displ...

Abstract

In a measurement processing apparatus for measuring a geometric feature of an object image: a measurement-reference-element setting unit automatically sets at least one first measurement reference element for use in measurement of the geometric feature of the object image, at at least one first position on the object image based on first image data representing the object image and position information indicating at least one second position of at least one second measurement reference element which is set on a measurement reference image corresponding to the object image; and a geometric-feature measurement unit measures the geometric feature of the object image based on the at least one first position of the at least one first measurement reference element.

Description

[0001] 1. Field of the Invention[0002] The present invention relates to a measurement processing apparatus for automatically measuring a geometric feature of an image based on at least one measurement reference element set on the image. For example, the image may be a medical image, and the geometric feature may be a distance between measurement reference points, or an angle between lines determined by measurement reference points.[0003] 2. Description of the Related Art[0004] Recently, the computed radiography (CR) has become commercially practical as a technique for obtaining a radiographic image having an extremely broad radiation exposure range, and is currently used for diagnosis in the medical field. The current CR systems use a stimulable phosphor (accelerated phosphorescent material), which stores a portion of radiation energy when the stimulable phosphor is irradiated with a radiation such as X rays, and emits accelerated phosphorescent light having energy corresponding to ...
