Three-dimensional simulation of aesthetic outcome from breast-conserving surgery compared with viewing photographs or standard care: randomized clinical trial.
(OXFORD UNIV PRESS, 2021-10-23)
INTRODUCTION: Over half of women with surgically managed breast cancer in the UK undergo breast-conserving treatment (BCT). While photographs are shown prior to reconstructive surgery or complex oncoplastic procedures, ...
Issues involved in the quantitative 3D imaging of proton doses using optical CT and chemical dosimeters.
(IOP PUBLISHING LTD, 2015-01-21)
Dosimetry of proton beams using 3D imaging of chemical dosimeters is complicated by a variation with proton linear energy transfer (LET) of the dose-response (the so-called 'quenching effect'). Simple theoretical arguments ...
3-D Microvascular Imaging Using High Frame Rate Ultrasound and ASAP Without Contrast Agents: Development and Initial In Vivo Evaluation on Nontumor and Tumor Models.
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019-05-01)
Three-dimensional imaging is valuable to noninvasively assess angiogenesis given the complex 3-D architecture of vascular networks. The emergence of high frame rate (HFR) ultrasound, which can produce thousands of images ...
Cancer heterogeneity and imaging.
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2017-04-01)
There is interest in identifying and quantifying tumor heterogeneity at the genomic, tissue pathology and clinical imaging scales, as this may help better understand tumor biology and may yield useful biomarkers for guiding ...
Radioactive 3D printing for the production of molecular imaging phantoms.
(IOP Publishing Ltd, 2020-09-08)
Quality control tests of molecular imaging systems are hampered by the complexity of phantom preparation. It is proposed that radioisotopes can be directly incorporated into photo-polymer resins. Use of the radio-polymer ...
MRI-based Assessment of 3D Intrafractional Motion of Head and Neck Cancer for Radiation Therapy.
(ELSEVIER SCIENCE INC, 2018-02-01)
PURPOSE: To determine the 3-dimensional (3D) intrafractional motion of head and neck squamous cell carcinoma (HNSCC). METHODS AND MATERIALS: Dynamic contrast-enhanced magnetic resonance images from 56 patients with HNSCC ...
Edge effects in 3D dosimetry: characterisation and correction of the non-uniform dose response of PRESAGE®.
(IOP PUBLISHING LTD, 2020-05-04)
Previous work has shown that PRESAGE® can be used successfully to perform 3D dosimetric measurements of complex radiotherapy treatments. However, measurements near the sample edges are known to be difficult to achieve. ...
Visualizing the autonomic and somatic innervation of the female pelvis with 3D MR neurography: a feasibility study.
(SAGE PUBLICATIONS LTD, 2020-12-01)
BACKGROUND: Treatment of female pelvic malignancies often causes pelvic nerve damage. Magnetic resonance (MR) neurography mapping the female pelvic innervation could aid in treatment planning. PURPOSE: To depict female ...
Evaluation of Performance Tradeoffs When Using Mechanically Swept 1-D Linear Arrays for 3-D DCE-US.
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2023-07-01)
Dynamic contrast-enhanced ultrasound imaging (DCE-US) may be used to characterize tumor vascular perfusion using metrics derived from time-amplitude curves (TACs). The 3-D DCE-US enables generation of 3-D parametric maps ...
Ultrasound Tomography Evaluation of Breast Density: A Comparison With Noncontrast Magnetic Resonance Imaging.
(LIPPINCOTT WILLIAMS & WILKINS, 2017-06-01)
OBJECTIVES: Ultrasound tomography (UST) is an emerging whole-breast 3-dimensional imaging technique that obtains quantitative tomograms of speed of sound of the entire breast. The imaged parameter is the speed of sound ...
