Spinal cord tolerance data for stereotactic body radiation therapy (SBRT) were extracted from published reports, reviewed, and modelled. For de novo SBRT delivered in 1 to 5 fractions, the following spinal point maximum doses (Dmax) are estimated be associated with a 1% 5% risk of myelopathy (RM): 12.4 14.0 Gy fraction, 17.0 2 20.3 3 23.0 4 25.3 fractions. reirradiation reported factors lower R...

Almost 20 years ago, Emami et al. presented a comprehensive set of dose tolerance limits for normal tissue organs to therapeutic radiation, which has proven essential to the field of radiation oncology. The paradigm of stereotactic body radiotherapy (SBRT) has dramatically different dosing schemes but, to date, there has still been no comprehensive set of SBRT normal organ dose tolerance limits...

The Collider Detector at Fermilab (CDF) radiation hardened silicon vertex detector (SVX’) is described. The new detector has several improvements over its predecessor such as better signal to noise and higher efficiency. It is expected to have a radiation tolerance in excess of 1 Mrad. It has been taking data for several months and some preliminary results are shown.

A novel multi-stage noise-shaping (MASH) delta-sigma (∆Σ) Time-to-Digital Converter (TDC) structure is proposed for applications in continuous-time pulsed time-offlight (TOF) rangefinders for nuclear reactor remote sensing, which requires both high resolution and multi MGy gamma-dose radiation tolerance. The converter, implemented in 0.13 μm CMOS, achieves a time resolution of 5.6 ps and an ENO...
