Background: RECIST 1.1 presents challenges when evaluating treatment response to angiogenesis inhibitors. The objective response rate, when evaluating the treatment effect of regorafenib, using RECIST 1.1, is < 2% and beneficial treatment could erron

Background A major concern following ablation treatment is the risk of insufficient heating leaving vital tumor tissue at the treatment site, leading to recurrent disease and reduced survival. Dynamic contrast-enhanced computed tomography (DCE-CT) ha

Publikováno v: Physics in Medicine and Biology, Vol. 63, No 14 (2018) P. 145015

We present an ultrasound-driven 4D magnetic resonance imaging (US-4DMRI) method for respiratory motion imaging in the thorax and abdomen. The proposed US-4DMRI comes along with a high temporal resolution, and allows for organ motion imaging beyond a

Quantum noise is common in CT images and is a persistent problem in accurate ventilation imaging using 4D-CT and deformable image registration (DIR). This study focuses on the effects of noise in 4D-CT on DIR and thereby derived ventilation data. A t

Purpose Physiological respiratory motion of tumors growing in the lung can be corrected with respiratory gating when treated with radiotherapy (RT). The optimal respiratory phase for beam-on may be assessed with a respiratory phase optimizer (RPO), a

Publikováno v: Cancer radiothérapie

The limited ability to control for a tumour's location compromises the accuracy with which radiation can be delivered to tumour-bearing tissue. The resultant requirement for larger treatment volumes to accommodate target uncertainty restricts the rad

Parathyroid adenoma is the most common cause of primary hyperparathyroidism. Advances in surgical techniques have made it possible to excise only the affected parathyroid gland in most cases. Imaging examinations play a fundamental role in the preope
