Abstract:
Objective:Three-dimensional (3D) ultrasound (US) is increasingly being introduced in the clinic,both for diagnostics and image guidance.Although dedicated 3D US probes exist,because of its expensive cost,3D US can also be acquired with the still frequently used two-dimensional (2D) US probes.Methods:Obtaining 3D volumes with 2D US probes is a two-step process.First,a positioning sensor must be attached to the probe for 2D image matching;second,a reconstruction of a 3D volume can be performed into a regular voxel grid.Results:This paper presents a way to realize the 3D US in irled-based Image Guided Radiotherapy using a homemade 2D US.Conclusions:The experiments demonstrate a method of saving costs and having advantages in clinic application.
