PURPOSE: To provide an ultrasonic diagnostic apparatus which enables displaying of a CFM image more naturally. CONSTITUTION: Comparators 761a-761d compare CFM values R0T0, R0T1, RIT0 AND RIT1 with a second threshold '0', and output 'Hi' when they coincide and 'Lo' when they do not coincide. When the CFM values R0T0, R0T1, R1T0 and R1T1 all coincide with the second threshold '0', an NAND circuit 762 and AND circuits 763a-763d output 'Lo' to multiplexers 764a-764d. Otherwise, outputs of the comparators 761a-761d are inputted into the multiplexers 764a-764d. The multiplexers 784a-784d select a replacement value RP'8' when 'Hi' is inputted from the AND circuits 763a-763d and the CFM values (F0T0, R0T1, R1T0, R1T1) when 'Lo' is inputted from the AND circuits 763a-763d. |
