OBJECT INFORMATION ACQUISITION APPARATUS, OBJECT INFORMATION ACQUISITION SYSTEM, DISPLAY CONTROL METHOD, DISPLAY METHOD, AND PROGRAM

摘要

In a known apparatus, when a user defines a specified region (201) in which characteristic information is to be acquired, it may be difficult for the user to easily recognize a corresponding scanning region (303) that is to be actually scanned with a receiver (104). An embodiment of the invention provides an object information acquisition apparatus including a receiver (104) configured to receive an acoustic wave and convert it into an electric signal, a scan control unit (107) configured to scan the receiver (104) at least in one direction, and a display control unit (130). Upon receiving information associated with a region specified (201) to be scanned to acquire characteristic information, the display control unit (130) outputs information for displaying an adjusted region (502) obtained by adjusting the specified region (201) such that a length of the specified region in a first direction corresponds to an integral multiple of a scanning width of the receiver in the first direction, also called scan pitch of the receiver. The apparatus can be, for instance, a photoacoustic imaging system.
