Measurement apparatus, movement control method, and program

摘要

Generally, as the time for mechanical scanning of an acoustic wave receiver increases, the load on an examinee also increases. The present invention provides the calculation of a target speed at which an acoustic wave receiver is caused to move for the measurement of an acoustic wave, using data of an emission period of pulsed light and data of an interval between target measurement positions in a subject being examined. In addition, the acoustic wave receiver is caused to move so as to reach an initial target measurement position at the target speed at a time when initial pulsed light for measuring an acoustic wave is emitted. After the target speed has been reached, the acoustic wave receiver is caused to move at a uniform speed which is equal to the target speed.

主权项

1. An apparatus comprising:
a light source configured to emit pulsed light; an acoustic wave receiver configured to receive an acoustic wave produced by irradiating a subject being examined with the pulsed light and to convert the acoustic wave into an electrical signal; a positional information detection unit configured to detect information on a position of the acoustic wave receiver; and a movement control unit configured to cause the acoustic wave receiver to move relatively to the subject being examined, a moving speed of the acoustic wave receiver being set based on the information on the position of the acoustic wave receiver, wherein the acoustic wave receiver includes a plurality of conversion elements configured to convert an acoustic wave into an electrical signal, and wherein the movement control unit is configured to cause the acoustic wave receiver to move so that a position where one of the conversion elements is positioned when one pulsed light is emitted coincides with a position where another of the conversion elements is positioned when another pulsed light is emitted.
