Abstract EN
Computed tomography (CT) has been widely used in the healthcare environment.
Presently, the radiation dose in CT is determined using the size-specific dose estimate (SSDE).
Accurate assessment of individual’s body size is essential for dose estimation.
In this study, we integrated a somatosensory controller with a CT scanner to measure patient’s anterior-posterior diameter (APD) and lateral diameter (LATD) and calculate the corresponding effective diameter (ED).
A total of 108 individuals with an average age of 38.6 years were enrolled in this study.
Microsoft Kinect was used to acquire the depth image of subjects.
A grayscale-to-surface height conversion curve was created using acrylic sheets for APD estimation.
The APD, LATD, and ED were measured and compared with the results obtained using F ruler and CT images.
The mean absolute differences for APD, LATD, and ED between Kinect and F ruler measurements were 5.2%, 1.3%, and 2.5%, respectively, while those between Kinect and CT measurements were 8.8%, 2.6%, and 5.0%, respectively.
Kinect can replace CT or F ruler for real-time body size measurements.
The use of the somatosensory controller has the advantages of simple, low cost, no radiation, and automatic calculation.
It can accurately estimate patient’s APD, LATD, and ED for SSDE.
