A photoacoustic probe and photoacoustic device implementing the photoacoustic probe may reduce an artifact caused by an ultrasonic wave generated in the photoacoustic probe without mounting a separate device. The photoacoustic probe and photoacoustic device implementing the photoacoustic probe may reduce an artifact by changing a configuration or a structure provided in the photoacoustic probe. The photoacoustic probe may receive a photoacoustic signal generated from an inner material of an object absorbing light of a predetermined wavelength and may include a piezoelectric module to convert the photoacoustic signal into an electric signal, and an object contact unit disposed on the front surface of the piezoelectric module, the object contact unit contacting the object and not absorbing the light of a predetermined wavelength.

A combined imaging apparatus in which heterogeneous imaging devices are combined and a method for controlling the same are disclosed. The combined imaging apparatus includes a photoacoustic imaging unit to irradiate an energy beam to a target part, an ultrasonic imaging unit to generate an ultrasonic wave, irradiate the ultrasonic wave to the target part, and collect an echo ultrasonic wave reflected from the target part to which the ultrasonic wave is irradiated or an ultrasonic wave generated from the target part in response to energy beam irradiation of the photoacoustic imaging unit. The ultrasonic imaging unit starts or stops operation according to an operation state of the photoacoustic imaging unit.
