ULTRASOUND DIAGNOSTIC DEVICE

Japanese Patent JP2018068851

A

PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic device capable of suppressing a decrease in image quality of ultrasound images more easily while suppressing a decrease in efficiency of a power supply part.SOLUTION: An ultrasound diagnostic device (1) that displays an ultrasound image on the basis of a received signal by an ultrasound probe with respect to an ultrasound wave reflected within a subject comprises: a power supply part (11) that includes at least one voltage conversion circuit (111) for converting input voltage into power supply voltage and then outputting it. The voltage conversion circuit has a coil (L), has a switching element (Tr) for switching a course of electric current flowing through the coil in accordance with a prescribed switching control signal, and outputs power supply voltage by repeating a switching operation in a state where the input voltage is supplied. The power supply part is provided with multiple coils, and the coils are arranged at such positions that a leakage magnetic field near an opening of at least one coil of the coils is partially cancelled by a leakage magnetic field from one or more other coils.SELECTED DRAWING: Figure 4
