4DCT is widely considered the standard for lung cancer radiation therapy treatment planning (TP) despite susceptibility to breathing-related motion artifacts that often render images unusable. Five-dimensional CT (5DCT), a model-...

Conventional diffusion-weighted MRI (DWI) uses single-shot echo planar imaging (ssEPI), which is highly susceptible to geometric distortion, limiting its use for radiotherapy guidance on MR-LINAC systems. Turbo-spin-echo (TSE) an...

This study investigates the use of a haptic ultrasound simulator to support the development of core competencies—including image acquisition, interpretation, and equipment handling—among undergraduate students enrolled in a Clini...

Background: Respiratory and gastrointestinal movements induce motion artifacts in cone-beam computed tomography (CBCT), compromising image quality for adaptive radiotherapy. Existing approaches, including phase-binned four-dimens...

Therapy Physics

Time-resolved volumetric MRI reconstructed from minimal k-space samples is critical for motion-adaptive radiotherapy to capture real-time deformable motion. We propose a Gaussian representation-based one-shot learning framework t...

Lung tumors are poorly visible on conventional on-board 2D X-ray imaging due to limited soft-tissue contrast and overlapping anatomy, posing a challenge for patient setup on proton therapy systems equipped with 2D X-ray imaging....

The excellent soft-tissue contrast provided by MRI offers improved 3D tumour delineation for radiotherapy beam adaptation on MRI-Linacs. However, long acquisition and reconstruction times pose a barrier to achieving volumetric MR...

Photon-counting detectors (PCD) exhibit high sensitivity for scattered photons, enabling kilovoltage (kV) scattered X-ray imaging with potential for real-time tumor tracking for lung cancer radiotherapy. The performance in this a...

During liver radiotherapy, respiratory-induced tumor motion can result in target underdose and increased irradiation of surrounding healthy tissue. Existing real-time image-guided approaches often require specialized equipment or...

Differentiating radiation necrosis from tumor recurrence after stereotactic radiosurgery (SRS) remains a major challenge in neuro-oncology, as conventional MRI often fails to reliably distinguish these tissue types. Magnetic Reso...
