Historically, anatomical CT and MR images were used to delineate the gross tumour
volumes (GTVs) for radiotherapy treatment planning. The capabilities offered by modern …

Charged particle beam radiotherapy requires dedicated measures to compensate for the
dosimetric influence of inter-and intra-fractional target motion. Independent of the delivery …

A tumor reaching the size of 1 cm3 (approximately 1 g wet weight) is commonly assumed to
contain 1 x 109 cells. This paper comments on the probable origin of this “magic” number …

Medical imaging systems often require the application of image enhancement techniques to
help physicians in anomaly/abnormality detection and diagnosis, as well as to improve the …

Purpose: The use of magnetic resonance imaging (MRI) in radiation oncology is expanding
rapidly, and more clinics are integrating MRI into their radiation therapy workflows. However …

The progressive integration of positron emission tomography/computed tomography
(PET/CT) imaging in radiation therapy has its rationale in the biological intertumoral and …

The emerging biological understanding of metastatic cancer and proof-of-concept clinical
trials suggest that debulking all gross disease holds great promise for improving patient …

The theory of task-based assessment of image quality is reviewed in the context of imaging
with ionizing radiation, and objective figures of merit (FOMs) for image quality are …

In modern radiotherapy, verification of the treatment to ensure the target receives the
prescribed dose and normal tissues are optimally spared has become essential. Several …

In radiation therapy (RT), staging, treatment planning, monitoring and evaluation of
response are traditionally based on computed tomography (CT) and magnetic resonance …
