Imaging apparatus for diagnosis, method of controlling the same, program, and computer readable storage medium

A method of controlling an imaging apparatus for diagnosis accommodating an imaging core which has an optical transceiver for transmitting light from a light source toward a vascular tissue and for receiving reflected light from the vascular tissue, and reconstructing a blood vessel image based on interference light data obtained by converting into an electric signal interference light in which measurement light obtained by rotating the imaging core by using a catheter which has an open hole at a distal end portion and reference light separated from the light from the light source are synthesized, the method of controlling an imaging apparatus for diagnosis comprising:

• generating line data in a radial direction from a rotary center position of the imaging core based on the interference light data;
• determining whether or not a foreign substance other than a predetermined liquid enters between the imaging core and an inner surface of the catheter based on distribution of signal strength values in the generated line data;
• and
• displaying a message which indicates that entrance of the foreign substance is detected in a case where the entrance of the foreign substance is determined.

A non-transitory computer readable medium containing a computer program having computer readable code embodied to carry out a method of controlling an imaging apparatus for diagnosis accommodating an imaging core which has an optical transceiver for transmitting light from a light source toward a vascular tissue and for receiving reflected light from the vascular tissue, and reconstructing a blood vessel image based on interference light data obtained by converting into an electric signal interference light in which measurement light obtained by rotating the imaging core by using a catheter which has an open hole at a distal end portion and reference light separated from the light from the light source are synthesized, the method of controlling an imaging apparatus for diagnosis comprising:

• generating line data in a radial direction from a rotary center position of the imaging core based on the interference light data;
• determining whether or not a foreign substance other than a predetermined liquid enters between the imaging core and an inner surface of the catheter based on distribution of signal strength values in the generated line data;
• and
