5.5.2.1　Measuring melanoma thicknesses

Thickness measurement is critical in the diagnosis of melanoma.Besides，tumor thicknesses are associated with different prognoses and treatment procedures.In 2006，Oh et al.imaged skin melanomas in vivo by using a table-top photoacoustic microscopy system.The results showed that both the top and bottom boundaries of the melanoma phantoms could be detected（Figure 5-10）.In addition，the measured thicknesses of the melanoma phantoms agreed well with the known values.To broaden the applicability to various anatomical sites，Oh et al.developed a hand-held photoacoustic microscopy system that could image melanomas in all tumor classifications，which is highly promising for clinical studies.(https://www.daowen.com)
