Experimental Study on Observation of original shape of Crop Root System with Multi Helical CT Technology

XIANG Zi-yun1, LUO Xi-wen 2, ZHOU Xue-cheng2,YAN Xiao-long2 , LUO Liang-ping3,,ZHAO Xiang-sheng3 (1. The people’s Hospital of Longgang District, Shenzhen 518172, China ; 2. South China Agricultural University, Guangzhou 510640 ,China; 3. Ji’nan University, Guangzhou 510630,China )  
objective: To study the value of multi – helical(slice) CT with 3D reconstruction in the observation and measurement of original shape of crop(plant) root system. Methods: Nine flowerpots of three kinds of crop which were growing in three different culture mediums were scanned with multi - slice CT(MSCT), The volume parameters of the root system of the 3 plants were transferred to the CT 3D workstation . Soft wares including MIP,SSP,MPR and VR for the processing of the figures were employed to construct the images. The images were evaluated by 2 physicians specialized in CT and 2 agriculture specialists. Results: The attempt to get in situ plant root images was made with using MSCT imaging technology and implemented visualization of plant root growing in different medium.Conclusion: The root system of plants cultured with organic media can be shown with MSCT,and MIP is the most effective software to display the root system .
