He has made significant contributions to the field of medical imaging, particularly in the area of real-time target position estimation and 4D imaging reconstruction. With a total of 2 patents, his work has the potential to enhance patient care and treatment accuracy.
Latest Patents
Loo's latest patents include a method and apparatus for real-time 3D target position estimation by combining single x-ray imaging and external respiratory signals. This innovative system estimates internal position information of a target in real-time using a gantry-mounted x-ray imager and a respiratory signal. The x-ray imaging is performed periodically to minimize radiation exposure. Initial parameters for the estimation model are established during a pre-treatment session using four-dimensional computed tomography (4D CT) alongside the patient's respiratory signal. The model parameters are subsequently updated during treatment based on periodic x-ray image data and the respiratory signal.
Another notable patent is the 4D anatomically based image selection procedure for medical imaging. This advancement provides improved 4D imaging reconstruction for patients who are breathing freely. In this method, 3D patient images from an imaging dataset are categorized according to respiratory displacement or phase. The bins are defined by ranges, ensuring that every image in the raw 3D dataset is included. The 4D reconstruction is achieved by selecting one 3D image from each bin at each patient position, maximizing the anatomical similarity of 3D images at adjacent positions.
