Description

technical field

[0001] The present invention relates to the field of three-mode cooperative imaging of ultrasonic imaging, photoacoustic imaging and photoacoustic spectrum imaging, and in particular to an ultrasonic photoacoustic photoacoustic spectrum three-mode imaging system and method. Background technique

[0002] Ultrasound imaging for medical diagnosis is widely used in medical diagnosis due to its advantages of non-ionizing radiation, high-resolution imaging of anatomical structures, and low cost. However, ultrasound imaging is generally sensitive to tissue structures with differences in acoustic impedance and blood flow with movement speed, and is not specific to other physical and chemical properties of tissues, so the diagnostic function is limited. In many medical clinical diagnoses, ultrasound imaging needs to be combined with other diagnostic methods to provide doctors with more specific information about the lesion.
