PMT-ROOT-XCT

Product Name: CT Scanning Imaging System of Plant Roots

Brand Model: PMT-ROOT-XCT

Manufacturer: PM-Tech GmbH

[Product Uses]

X-ray CT system for measuring the roots of small plants, which can perform transmission imaging and tomography imaging of plant roots. PMT-ROOT-XCT is a new, high-efficiency, high-precision and non-destructive measurement system, which is used for in-situ imaging analysis of the root system of potted plants. It can not only take stereoscopic X-ray photos and tomography of the root system, but also monitor the growth of root system in different stages of plants for a long time. PMT-ROOT-XCT is very suitable for studying the dynamic response of plant roots to stress, with the world's most advanced GPU acceleration algorithm, which improves the fault reconstruction speed by 3 times. The imaging of the system is separated from computer control, which can realize remote control and radiographic shooting, with a safety interlock device and a working status warning device, which can effectively guarantee the body radiation requirements and wrong operation of the experimenter.

[Parameters Available]

1.1 The product is equipped with 2 sets of supporting software (standard) including ImageJ and RootAnalysis to assist in processing images to obtain root length, root angle and root spatial distribution (relative to the central axis).

Biomass parameters determination: a variety of biomass determination parameters, such as horizontal biomass (total value, mean value, median value, standard difference value, maximum value, maximum position, minimum value, minimum position, etc.), vertical biomass, root horizontal distribution, root length estimate, etc.

1.1. Root topology parameter determination: Under this function, 3 hierarchical modes of Pregizer, topology and user-defined can be freely switched, which can measure the parameters, such as number of roots, mean of weighted average width, mean of weighted average angle, average projection area, length standard deviation, standard deviation of weighted average width, standard deviation of weighted average angle, etc. of different levels, perfect fitting of tortuous roots by dragging key nodes, specify root parent-child topology, so as to automatically determine the root total projection area, total volume, average length, average width, average angle, angle standard deviation, volume standard deviation, number of connections, relationship angle and other topological parameters. The 3 modes can automatically analyze the length and bifurcations of the main root or any side root and display the corresponding parameters of any diameter section of the marked root separately (the number of grades and the range of the diameters of the grades can be arbitrarily changed, customized at unequal intervals), which can simultaneously perform root bifurcation clipping, merging, connection and other corrections, and the corrections can be regressed to get 100% correct results quickly.

1.2. Single-root parameter determination: a variety of single-root parameters, such as length, weighted average width, maximum width, minimum width, width standard deviation, weighted average angle, maximum length, minimum length, angle standard deviation, surface area, projection area, etc.;

1.3. Direction trend parameters: measure the width trend, angle trend, surface area trend, projection area trend, volume trend with the trend of root length;

1.4. Mycorrhizal parameter determination: The product can measure the fractal dimension of root system automatically by box dimension method, and analyze the proportion of rhizobia volume in the root system to determine the contribution of rhizobia objectively. Meanwhile, it can measure conventional parameters such as mycorrhizal length, weighted average width, maximum width, minimum width, width standard deviation, maximum length and minimum length and so on.
