Ultrasonic inspection and imaging instrument

An ultrasonic inspection and imaging instrument for scanning an object under examination, said object having an interior test surface for detecting an echo level emanating from a position corresponding to a focal position obtained from said object under examination by means of a focusing-type probe and for making the echo level a measured value, and for generating display data according to said measured value in order to display a measurement picture of said test surface on the screen of a display, said instrument comprising:

• scanning means for scanning said object under examination in first and second directions along said test surface and in a third direction along a depth direction of said object under examination;
• image processor means for carrying out, by controlling said scanning means, slant scanning in the third direction during the scanning in either the first or second direction, for generating said display data according to the measured value obtained in either first or second direction in order to display a measurement picture on the screen of said display, and for placing said probe at a position in the third direction where the measured value is collected with respect to an image portion in response to an input signal when the input signal is externally supplied;
• and
• input means for feeding, to said image processor means, said input signal for indicating that said image portion has been selected from said measurement picture, said input means being connected to said image processor means.

An ultrasonic inspection and imaging instrument for scanning an object under examination, said object having an interior test surface for detecting an echo peak value emanating from a position corresponding to the focal position obtained from said object under examination by means of a focusing-type probe and for making the echo peak value a measured value, and for generating display data according to said measured value in order to display a measurement picture of said test surface on the screen of a display, said instrument comprising:

• scanning means for scanning said object under examination in a first direction along said test surface and in a second direction along a depth direction of said object under examination;
• and
• image processor means for carrying out, by controlling said scanning means, scanning in the second direction simultaneously with the first direction to collect said measured value at each of a plurality of measurement points determined by positions in the first and second directions, and for generating said display data for displaying a test picture in conformity with at least the second direction with respect to said measurement point, to display said test picture on the screen of said display for focusing purposes, said image processor means being equipped with a memory for storing relevant information for indicating the relation between a position at which the image is displayed on said test picture and a position in the second direction at which said measured value of the display data has been collected, said image processor means including input means for generating information indicating the position of an image portion when an image portion with respect to said test picture is selected, said image processor means being used to obtain the position in the second direction according to said relevant information and the information showing the position of said image portion from said input means, and to set said ultrasonic probe in position for focusing purposes.
