Title: Specific area sampling method for image
Inventor: GOTO YOSHIHIRO
IPC: A61B6/03
Filed: 1994-02-08
Abstract: PURPOSE:To prevent processing time from being increased gradually without performing unrequired processing when a part of a specific area that is a sampling object is not required to sample and even when point replacement/addition processing is performed repeatedly and to prevent the sampling of even curved shape from leaking by setting a boundary with an unprocessed area as a protect line arbitrarily. CONSTITUTION:It is assumed that, for example, a part from which a hatched part 23 is eliminated out of a partial internal organ or lesion 22 in a diagnostic image 21 displayed on a monitor screen 20 is not sampled. In such a case, a cursor 25 is moved by using a mouse 24, and the protect line 26 is drawn on the diagnostic image 21. At this time, the value of picture element of the protect line 26 is set at a value separated apart from the range of a picture element set in advance as the specific area to be sampled. For example, when the cutis is sampled from a CT image, a CT value absolutely not relating to the cutis is written. In this way, the oblique line part 23 to where a chain is not moved is eliminated, and a sampling area can be limited.
