Performance of Hardware Accelerated Bone Segmentation with Noise Reduction on 4DCT Images



Software, hardware and results generated from testing the performance of a bone segmentation algorithm
implemented in both hardware and software for segmenting bone in medical

The bone segmentation algorithm used was one described by Haas et al.
(doi: 10.1088/0031-9155/53/6/017). The algorithm was implemented in full in
software. Details of this implementation can be obtained from the following
A simplified version of this algorithm for processing image volumes was developed for hardware implementation, which was implemented in both hardware and software. The results of applying the simplified algorithm can be obtained from the following DOI:
The simplified algorithm was extended to improve its segmentation performance on noisy image data. This was again implemented in hardware and software and it is the data associated with this work that is presented here.

The software algorithms were executed on a 2.6GHz Intel Core i5-3230M CPU,
while the hardware system was implemented on a Xilinx Zynq Z7020 device on an
AvNet ZedBoard development board.

Image data in the form of 4-dimensional computed tomography (4DCT) scans of a
Modus Medical QUASAR Programmable Respiratory Motion Phantom (Modus Medical
Devices Inc. London, ON) were obtained from Edinburgh Cancer Centre (n=8) and
used as the input data. Each of the datasets contained fifteen 3D image volumes
that were each segmented.

The time taken to process each image volume and each slice of each image volume
was recorded for each of the three implementations.
