Line plus arc source trajectories and their R-line coverage for long-object cone-beam imaging with a C-arm system.

Physics in medicine and biology

Yu Z, Wunderlich A, Dennerlein F, Lauritsch G, Noo F.
PMID: 21606557
Phys Med Biol. 2011 Jun 21;56(12):3447-71. doi: 10.1088/0031-9155/56/12/001. Epub 2011 May 23.

Cone-beam imaging with C-arm systems has become a valuable tool in interventional radiology. Currently, a simple circular trajectory is used, but future applications should use more sophisticated source trajectories, not only to avoid cone-beam artifacts but also to allow...

Combining Acceleration Techniques for Low-Dose X-Ray Cone Beam Computed Tomography Image Reconstruction.

BioMed research international

Huang HM, Hsiao IT.
PMID: 28676860
Biomed Res Int. 2017;2017:6753831. doi: 10.1155/2017/6753831. Epub 2017 Jun 05.

BACKGROUND AND OBJECTIVE: Over the past decade, image quality in low-dose computed tomography has been greatly improved by various compressive sensing- (CS-) based reconstruction methods. However, these methods have some disadvantages including high computational cost and slow convergence rate....

Diagnostic performance of cone-beam computed tomography for scaphoid fractures: a systematic review and diagnostic meta-analysis.

Scientific reports

Yang TW, Lin YY, Hsu SC, Chu KC, Hsiao CW, Hsu CW, Bai CH, Chang CK, Hsu YP.
PMID: 33510347
Sci Rep. 2021 Jan 28;11(1):2587. doi: 10.1038/s41598-021-82351-9.

Scaphoid fractures are the most common carpal fractures. Diagnosing scaphoid fractures is challenging. Recently, cone-beam computed tomography (CBCT) has been shown to be a promising strategy for diagnosing scaphoid fractures. The diagnostic performance of CBCT remains inconclusive in the...

Method of visualisation influences accuracy of measurements in cone-beam computed tomography.

Journal of cranio-maxillo-facial surgery : official publication of the European Association for Cranio-Maxillo-Facial Surgery

Patcas R, Angst C, Kellenberger CJ, Schätzle MA, Ullrich O, Markic G.
PMID: 26109234
J Craniomaxillofac Surg. 2015 Sep;43(7):1277-83. doi: 10.1016/j.jcms.2015.05.001. Epub 2015 May 29.

This study evaluated the potential impact of different visualisation methods of cone-beam computed tomography (CBCT) on the accuracy of linear measurements of calcified structures, and assessed their interchangeability. High resolution (0.125 mm voxel) CBCT scans were obtained from eight...

Signal detection and location-dependent noise in cone-beam computed tomography using the spatial definition of the Hotelling SNR.

Medical physics

Brunner CC, Abboud SF, Hoeschen C, Kyprianou IS.
PMID: 22755705
Med Phys. 2012 Jun;39(6):3214-28. doi: 10.1118/1.4718572.

PURPOSE: Quality assurance in computed tomography (CT) is commonly performed with the Fourier-based modulation transfer function (MTF) and the noise variance, while more recently the noise power spectrum (NPS) has increased in popularity. The Fourier-based methods make assumptions such...

Computed Tomography-Assisted Thoracoscopic Surgery: A Novel, Innovative Approach in Patients With Deep Intrapulmonary Lesions of Unknown Malignant Status.

Investigative radiology

Kostrzewa M, Kara K, Rathmann N, Tsagogiorgas C, Henzler T, Schoenberg SO, Hohenberger P, Diehl SJ, Roessner ED.
PMID: 28141614
Invest Radiol. 2017 Jun;52(6):374-380. doi: 10.1097/RLI.0000000000000353.

OBJECTIVES: Minimally invasive resection of small, deep intrapulmonary lesions can be challenging due to the difficulty of localizing them during video-assisted thoracoscopic surgery (VATS). We report our preliminary results evaluating the feasibility of an image-guided, minimally invasive, 1-stop-shop approach...

PMID: 23198420
Sheng Wu Yi Xue Gong Cheng Xue Za Zhi. 2012 Oct;29(5):851-4.

Cone-beam CT (CBCT) of Elekta can be used to analyze the setup errors in intensity modulated radiotherapy. A total of 240 patients with head and neck cancer were chosen in the period from October, 2009 to October, 2010. Their...

Centers and centroids of the cone-beam projection of a ball.
