Three-dimensional reconstruction of the uterine vascular supply through vascular casting and thin slice computed tomography scanning.

It was the objective of this study to construct a model of the uterine vascular supply through vascular casting and thin slice computed tomography scanning. This will provide a teaching aide for the understanding of uterine artery embolization (UAE) procedures, as well as normal uterine and ovarian arterial anatomy. Using 20% chlorinated poly vinyl chloride, we infused and cast a set of a normal uterus, vagina and bilateral adnexa through the uterine artery and ovarian artery.

[Study of three-dimensional computerized reconstruction and CT scanning with thin slice after filling hepatic duct system].

Objective: To establish the modal of perfusing and casting in hepatic duct system and explore the methods of three dimensional reconstruction with CT scanning image after filling hepatic duct.

Methods: All canal of livers with integral porta hepatic were perfused with various filling material after pretreatment, then fixed and casted. Hepatic preparations that had been perfused were put into the model of modelling abdominal cavity and scanned with thin slice.

[Study of three-dimensional reconstruction of digitized virtual hepatic images].

Objective: To study the methods of three-dimensional reconstruction of digitized virtual hepatic.

Methods: Images of DSCF 2511-2520 were taken from the database of digitized Virtual Chinese Human female No. 1 (VCH-F1).

[Improvement of specimen sectioning technique for Virtual Chinese Human study].

Objective: To improve the image quality of the specimen serial sections for establishing the Virtual Chinese Human dataset and to extend the durability of the milling tools.

Method: The image quality of the serial sections obtained by using tangential and radial indexable milling tools was compared.

Results And Conclusion: Compared with radial milling tools, tangential ones were more suitable for use in this study to ensure high-quality section image acquisition, showing the advantages such as high efficiency, long durability and low cost.

Construction of dataset for Virtual Chinese Male No.1.

Objective: To establish digitized Virtual Chinese Human Male No.1 (VCH-M1) image dataset with a 0.2-mm equal interval.

[Research report of experimental database establishment of digitized virtual Chinese No.1 female].

Objective: To establish digitized virtual Chinese No.1 female (VCH-F1) image database.

Methods: A 19 years old female cadaver was scanned by CT, MRI, and perfused with red filling material through formal artery before freezing and em- bedding.
