    • Examples disclosed herein relate to determining a power difference in sensor signals. Examples include a first sensor to transmit a first ultrasonic signal into a pregnant woman and to receive a second ultrasonic signal; and a second sensor to transmit a third ultrasonic signal into the pregnant woman and to receive a fourth ultrasonic signal. A processing resource determines a first power difference of the first sensor according to a difference between respective powers of the first ultrasonic signal and the second ultrasonic signal and is to determine a second power difference of the second sensor according to a difference between respective power of the third ultrasonic signal and the fourth ultrasonic signal. In examples, the processing resource is to determine a relative location of the fetal heart according to a comparison of the first power difference and the second power difference.

    •  基準フレーム選択部は、胎児の心臓を表すフレーム列の中から基準フレームを選択する。候補領域群設定部は、フレーム列を構成する個々のフレームに対して候補領域群を設定する。相関値演算部は、基準フレームとそれ以外の各フレームとの間で候補領域ごとに相関値を演算する。これにより、複数の候補領域に対応した複数の相関値波形が生成される。安定化波形部分特定部は、相関値波形ごとに安定化波形部分を特定する。安定化領域特定部は、複数の安定化波形部分の中で、安定化度が最も高い安定化波形部分(すなわち、安定化が最も高い候補領域)を特定する。心拍数演算部は、安定化度が最も高い安定化波形部分に基づいて胎児の心拍情報(心拍数等)を演算する。
    • 在本发明中,参考帧选择单元从示出胎儿的心脏的帧序列中选择参考帧。 候选区域组设置单元为构成帧序列的每个帧设置候选区域组。 相关值计算单元针对每个候选区域计算参考帧和所有其他帧之间的相关值。 由此,生成与多个候补区域对应的多个相关值波形。 稳定波形部分指定单元为每个相关值波形指定稳定的波形部分。 稳定区域指定单元从多个稳定波形部分中指定具有最高稳定度的稳定波形部分(换句话说,具有最高稳定度的候选区域)。 心率计算单元基于具有最高稳定度的稳定波形部分来计算胎儿的心跳信息(心率等)。
