Traditional displacement sensors and computer vision technologies exhibit significant limitations when measuring multiple targets, including restrictions related to the measurement environment, manual tagging wiring issues associated with sensors. This paper proposes a method for multi-point vibration that integrates bicubic interpolation, sparse optical flow oriented FAST rotated BRIEF (ORB) detection algorithms, addressing aforementioned limitations. The proposed eliminates need tags...
To compare the image quality of low-dose CT urography (LD-CTU) using deep learning reconstruction (DLIR) with conventional CTU (C-CTU) adaptive statistical iterative (ASIR-V).This was a prospective, single-institutional study excretory phase images for analysis. Patients were assigned to LD-DLIR group (100kV and automatic mA modulation noise index (NI) 23) C-ASIR-V NI 10) according scan protocols in phase. Two radiologists independently assessed overall quality, artifacts, sharpness urinary...
Bone density measurement is an important examination for the diagnosis and screening of osteoporosis. The aim this study was to develop a deep learning (DL) system automatic bone mineral (BMD) osteoporosis using low-dose computed tomography (LDCT) images.This retrospective included 500 individuals who underwent LDCT scanning from April 2018 July 2021. All images were manually annotated by radiologist cancellous target vertebrae post-processed quantitative (QCT) software identify Patients...
This paper shows the verification work of SARAX code system in reactor core transient calculation based on simplified EBR-II Benchmark. The is an analysis package developed by Xi'an Jiaotong University and aims at advanced R&D. In this work, a neutron-photon coupled power model spatial-dependent reactivity feedback were introduced. To verify models used SARAX, SHRT-45R test was to ULOF with input flowrate change curve fitting from reference. With model, gave close results both fraction peak...
Abstract Objectives To evaluate the clinical value of using a split-bolus contrast injection protocol in improving image quality consistency and diagnostic accuracy lower extremity CT angiography (CTA). Methods Fifty (mean age, 66 ± 12 years) 39 11 patients underwent CTA arteries fixed-bolus schemes, respectively. The objective subjective 2 groups were compared efficacy for degree vessel stenosis was digital subtraction as gold standard. A P < .05 considered statistically significant....
Abstract Objectives To explore the application value of body mass index (BMI)-based kilovoltage peak (kVp) selection and contrast injection protocol combined with different adaptive statistical iterative reconstruction V (ASIR-V) strengths in renal computed tomography angiography (CTA) reducing radiation medium (CM) doses. Methods One-hundred CTA patients were prospectively enrolled divided into individualized kVp group (group A, n = 50) conventional 100 B, 50), both automatic tube current...
Purpose: To investigate the feasibility and requirement for intra‐fraction on‐line multiple scanning particle beam range verifications (BRVs) with in‐situ PET imaging, which is beyond current single‐beam BRV extra factors that will affect BR measurement accuracy, such as diameter, separation between beams, different image counts at positions. Methods: We simulated a 110‐MeV proton 5‐mm diameter irradiating uniform PMMA phantom by GATE simulation, generated nuclear interaction‐induced...
Purpose: Cone‐beam CT (CBCT) is widely used in image‐guided radiation therapy. The high imaging dose from repeated uses a clinical concern and its image quality impeded by large amount of scattered photons. We propose to solve these two problems via random undersampling method. have performed Monte Carlo (MC) simulation studies for an initial test the Methods: place moving beam blocker with blocking pattern front x‐ray source. It blocks projection pattern, which varies among projections....
Purpose: Graphics Processing Unit (GPU) has become increasingly important in radiotherapy. However, it is still difficult for general clinical researchers to access GPU codes developed by other researchers, and developers objectively benchmark their codes. Moreover, quite often see repeated efforts spent on developing low-quality The goal of this project establish an infrastructure testing codes, cross comparing them, facilitating code distributions radiotherapy community. Methods: We a...
Conclusions: A novel modeling of the OER that explicitly includes dependence on ion type and dose per fraction was implemented.The model successfully included in a TPS to evaluate impact hypoxia with different species.
Purpose: Cone beam CT (CBCT) has been widely used for patient setup in image guided radiation therapy (IGRT). The dose from CBCT scans is a clinical concern. purpose of this study to quantitatively evaluate brain cancer patients under IGRT using GPU‐based Monte Carlo calculation package gCTD. Methods: We first performed measurements water phantom scanned Varian OBI system and the measurement data are commission Eight studied. For each patient, distribution standard head scan protocol...
Purpose: To investigate image quality as a function of number projections and tube load per projection in compressive sensing (CS) based low-dose cone beam CT (CBCT), achieve optimal scan protocols guided radiation therapy (IGRT). Methods: We have performed CS-based CBCT reconstruction with different combinations (from 46 to 364) mAs 0.2 2.4 mAs/view), which covers the whole clinically relevant range. Image is assessed each case. On this basis, are analyzed according various IGRT...
Purpose: Researchers write many computer programs with unique implementations, usually requiring a great amount of effort for other researchers to learn how install, configure, and use. Some require specialized hardware platforms such as GPU workstation or CPU cluster, which may not readily available researchers. This work develops general web platform ‘wrap’ radiotherapy software tools into user friendly, browser‐based interface. Methods: We developed wrapper based on existing technologies...
