In this study,we obtained optical coherence tomography (OCT) images of hysteromyoma at different depths with a full field OCT (FFOCT) system,and then a fractal analysis of hysteromyoma was performed.It can be seen from the OCT imag es that the morphological structures of hysteromyoma are different at different depths in the same location.To quantitatively deseribe changes of the structural characteristics of tissues with depth,Fourier transforms were performed to gene rate the distributions of the power spectrum of the imaging signales at differen t depths,and a formula fit was carried out to fine the fractal parameter,providi ng a quantitative fractal representation of the structures of hysteromyoma.The f ractal analysis of morphological structures of hysteromyoma can provide us new q uantitative knowledge about tissue structure.The new method isa suplement of qua ntitative methods,and has a great diagnostic value,especially for detecting canc er at early stages.
