PROBLEM TO BE SOLVED: To provide a medical diagnostic apparatus capable of suppressing influence of temperature fluctuation to a biological information signal even when the temperature around a receiving circuit is fluctuated, and obtaining accurate diagnostic information.SOLUTION: A receiving signal is obtained for each of predetermined obtained intervals using an array transducer (S1), temperature fluctuation is calculated based on temperature information around a receiving circuit obtained at a predetermined interval by a temperature sensor (S2), a sound ray signal generated in the receiving circuit is corrected based on a value of the temperature fluctuation and a peculiar correction coefficient of an ultrasonic probe and an obtained interval of the receiving signal (S4) when the temperature fluctuation around the receiving circuit is not below the predetermined value (S3), and an ultrasonic image is generated base on the corrected sound ray signal (S5). |
