ARISA Computerized Image Design

The ARISA computerized image design invented by the 701 Research Institute of the China Aero-Space Industry Corporation includes a clothing-on system and hair-complete system. By clothing-on system, garments of different styles can be automatically shown on the television screen for customers’ choice. At one press of the keyboard, another style can be seen. Customers can even try to change color and pattern of clothing material for the garment they have chosen, so as to achieve total satisfaction. If a customer’s image is recorded by camera beforehand, the system will, according to

Deep tissue near-infrared imaging for vascular network analysis

Subcutaneous vein network plays important roles to maintain microcirculation that is related to some diagnostic aspects.Despite developments of optical imaging technologies,still the difficulties about deep skin vascular imaging have been continued.On the other hand,since hemoglobin con-centration of human blood has key role in the veins imaging by optical manner,the used wavelength in vascular imaging,must be chosen considering absorption of hemoglobin.In this research,we constructed a near infrared(NIR)light source because of lower absorption of hemoglobin in this optical region.To obtain vascular image,reflectance geometry was used.Next,from recorded images,vascular network analysis,such as calculation of width of vascular of interest and complexity of selected region were implemented.By comparing with other modalities,we observed that proposed imaging system has great advantages including nonionized radiation,moderate penetration depth of 0.5-3 mm and diameter of 1 mm,cost-effective and algorit hmic simplicity for analysis.

Design of axial flaps with color Doppler flow imaging technique for repairing deep wounds of heels

To report the methods and effect of axial pattern flap on lower limb in repairing deep wounds of heels by using color Doppler flow imaging (CDFI) technique so as to solve the ever before problems that the vessel can not be displayed in designing axial flap.Methods Suitable axial flaps on lower limbs were selected according to the character of the wounds.There were 25 flaps including 10 cases of the distal-based sural neurovascular flap,nine medial sole flap and six medial leg flap.All the axial pattern flaps were designed on the basis of traditional design ways before operation;then,CDFI appliance with high resolution was used to examine the starting spot,exterior diameter,trail and length of the flap’s major artery.The flaps were redesigned according to the results of CDFI and transferred to cover the wounds.In the meantime,both the results of operation and examination were compared.Results The major artery’s starting spot,exterior diameter,trail and anatomic layers were displayed clearly,in consistency with the results of operation.The flaps survived completely and recovered well,with perfect appearance,color and arthral function.Conclusion CDFI is a simple,macroscopic and atraumatic method for designing the axial pattern flap on lower limb,can provide more scientific and accurate evidence for preoperative determination of flap transplantation and is worthy of clinical application.10 refs,4 figs,2 tabs.

Blended Teaching Mode Based on“Cloud Class+PAD Class”in the Course of Computer Graphics and Image Design

As a teaching tool,Cloud class is specially developed for teaching and learning in mobile circumstance,and the PAD(Presentation Assimilation Discussion)class acts as a creative teaching mode.The combination of Cloud class and PAD class helps build online-offline blended teaching model.In this paper,a Cloud+PAD class mode is proposed.An experiment of teaching is implemented and the practical effectiveness is evaluated and verified.The experimental results show,compared with the conventional teaching method,the proposed teaching mode is capable of creating more high-level,innovative and complex teaching content,and thereby noticeably enhancing students’learner autonomy and motivating them to develop creativity.
