    •  チャンネル数を増加させることなく、設定する環状領域を幅を狭め、焦点音圧を高めることが可能な超音波撮像装置を提供する。  制御部は、反射波の波面51~54と探触子1の2次元平面との交線に沿って、信号線よりも多い数の環状領域421~42pを設定する。制御部は、設定した複数の環状領域のうち焦点との距離が超音波波長λの整数倍ずつ異なる複数の環状領域(0,0)、(0,1)、(0,2)を選択し、選択した複数の環状領域内に位置する振動素子を、同一の信号線に接続する。これにより、選択した複数の環状領域から受信信号同士は、波長に相当する時間ずつずれた複数の時刻に到着し、互いに打ち消し合わない。また、信号線よりも多い数の環状領域を設定することができ、環状領域の幅を狭めることができる。

    • An ultrasonic inspection apparatus comprising a large number of array oscillators (101 ∩ 10n) in a columnar shape. The oscillators are excited sequentially to generate a sequence of ultrasonic beams to scan an object of inspection. The reflection from the object is analyzed to inspect the surface condition of the object and the existence of any fault inside it. Before an inspection, ultrasonic scanning of a reference material having a uniform quality and free from any defects is performed in order to collect the reference data for each ultrasonic beam (each channel). Correction values are prepared on the basis of these reference data and the reception signals obtained by the ultrasonic scanning of the object are corrected by use of these correction values. One correction means determines the ratio of the mean value of the reference value to the reference value of the channel for each channel, multiplies the reception signal of the same channel by the ratio as the correction value and uses the product as the data to be displayed on a display unit (21). Another correction means determines a damping ratio to the reference value of each channel so that the reference value of each channel becomes a minimum value or a predetermined value below the minimum value, and the reception signal of the same channel is damped by a sensitivity leveling circuit (31) using the damping ratio. Variance of sensitivity between the channels can be eliminated by these correction means.
