	1	Microwaves trigger thermo-acoustic ultrasound generation显示文摘Ultrasound is one of the most common modalities for diagnostic imaging of the body(biomedical imaging)and engineering structures(non-destructive evaluation–NDE).This is partly due to the lack of safety concerns when probing the body with acoustic waves and the availability and relative affordability of the equipment.Another very important strength of ultrasound is the penetration depth of ultrasonic waves into opaque materials.Frequencies in the low MHz range can usually penetrate deep inside tissue and other structures.However,ultrasound also has some drawbacks:in particular it usually has poor spatial resolution and requires the use of a range of special frequency band-limited transducers.There is on-going research work that tries to improve the spatial resolution by investigating techniques such as super-resolution algorithms,1 micro-bubbles2 and photo-acoustic(PA)imaging.
