摘要:
目前在国内皮肤疾病的临床诊疗中,皮肤三维成像仍然是一个未被解决的问题,我们因而提出用甚高频超声对皮肤三维成像。用中心频率为50 MHz的机械三维超声探头采集正常人前臂上侧皮肤切片,用光线投射算法和可视化工具包重建前臂上侧皮肤。重建100张576x760像素的图像所需的时间为1.1 s,三维重建图能够清晰的显示皮肤的表皮、真皮、真皮纤维和皮下组织,通过体数据的任意切面可以清晰的观察到血管的形态、走向及血管内红细胞散射斑点。甚高频超声皮肤三维成像克服了传统成像方式在皮肤成像中的不能兼顾深度和精度的缺点,对于皮肤疾病的诊断以及皮肤手术指导具有重要意义。
Abstract:
Three-dimensional imaging of skin is still an outstanding problem at present clinical diagnosis and treatment of skin diseases in China. Therefore, a three-dimensional imaging of skin with very-high-frequency ultrasound was proposed. Slices for reconstruction were collected from upper forearm skin of normal people with a mechanical 3D ultrasound probe the center frequency of the probe is 50 MHz. Ray casting algorithm and visualization toolkit were used to reconstruct the skin of the upper forearm. 1.1 s was needed to reconstruct a volume data with 100 frames 576x768 pixel images, 〖JP2〗The three-dimensional reconstructed images could display the epidermis, dermis, dermis fibers and subcutaneous clearly, the shape and direction of the vessel and the scattering spots of intravascular red blood cell could also be clearly observed through the arbitrary section of the volume data. Very-high-frequency ultrasound three-dimensional skin imaging overcomes the shortcomings of traditional imaging methods in the skin imaging, which cannot guarantee the depth and accuracy simultaneously. It is of great significance for the diagnosis of skin diseases and the guidance of skin surgery.
