We developed a miniature quantitative optical coherence elastography (qOCE) instrument with an integrated Fabry-Perot force sensor, for in situ elasticity measurement of biological tissue. The technique has great potential biomechanics modeling and clinical diagnosis. designed the fiber-optic qOCE probe that was used to exert compressive deform tissue at tip probe. Using space-division multiplexed tomography (OCT) signal detected by spectral domain OCT engine, we were able quantify...
Speckle decorrelation analysis of optical coherence tomography (OCT) signal has been used in motion tracking. In our previous study, we demonstrated that cross-correlation coefficient (XCC) between Ascans had an explicit functional dependency on the magnitude lateral displacement (δx). this evaluated sensitivity speckle tracking using derivative function XCC(δx) variable δx. We can be maximized. other words, OCT optimized by signals with appropriate amount for XCC calculation. Based finding,...
Our aim was to evaluate the histologic characteristics of tissue extracted on probe immediately after radiofrequency ablation malignant tumors in liver.From April December 2001, 20 ablations were performed 19 patients with primary (n = 17) and metastatic 2) liver masses. Track according device protocol each ablation. Tissue adherent all passes. All pieces found collected preserved formalin.Tissue examined by study pathologist. In eight (40%) specimens, coagulation necrosis present. five...
In this study, we performed dual-modality optical coherence tomography (OCT) characterization (volumetric OCT imaging and quantitative elastography) on human breast tissue specimens. We trained validated a U-Net for automatic image segmentation. Our results demonstrated that segmentation can be used to assist clinical diagnosis cancer, is powerful enabling tool advance our understanding of the characteristics tissue. Based obtained from 3D images, significant morphological heterogeneity in...
We investigate a spatial coordinate correction (SCC) method to track motion with high accuracy for optical coherence elastography (OCE).Through SCC, we refer the displacement field tracked by tomography (OCT) in loaded sample individual material points defined fixed system.SCC allows OCE perform spatially and temporally unambiguous tracking of enables accurate mechanical characterization biological tissue cancer diagnosis tumor margin assessment.In this study, validated effectiveness based...

The purpose of this study was to determine the frequency and outcomes breast malpractice suits among all enrollees in One Call Medical Inc.'s panel interpreting radiologists nationally evaluate state-by-state variations. 8401 enrolled had 4764 suits, which 826 were related disease. In New York Jersey, ratio Radiologists 0.28 0.27, twice as much any other state. Breast radiology have a wide variation across country with Jersey far exceeding others relative number multiple suits.
Introduction: Granular cell tumors (GCT) are rare soft tissue neoplasms of neural origin that occur in the breast 6% cases.Although malignant GCTs extremely rare; due to unknown clinical course and radiographic similarities invasive mammary carcinoma, wide surgical excision is currently recommended upon diagnosis all granular tumors.We propose distinct features these may identify their benign nature, thus possibly sparing resection.Method: This a retrospective chart review patients with from...
Optical coherence tomography (OCT) is a versatile imaging technique and has great potential in tissue characterization for breast cancer diagnosis surgical guidance. In addition to structural difference, cancerous usually stiffer compared normal adipose tissue. However, previous studies on compression optical elastography (OCE) are qualitative rather than quantitative. It challenging identify the status of based OCE results obtained from different measurement sessions or patients. Therefore,...
Optical coherence tomography (OCT) signal can provide microscopic characterization of biological tissue and assist clinical decision making in real-time. However, raw OCT data is noisy complicated. It challenging to extract information that directly related the pathological status through visual inspection on huge volume streaming from high speed engine. Therefore, it critical discover concise, comprehensible massive novel strategies for analysis. In this study, we perform Shannon entropy...
We investigated a deep learning strategy to analyze optical coherence tomography image for accurate tissue characterization based on single fiber OCT probe. obtained data from human breast specimens. Using adipose (normal tissue) and diseased as confirmed in histology, we trained validated convolutional neural network (CNN) classification. demonstrated tumor margin identification CNN classification of at different spatial locations. further imaging manually scanned Our results that...
We performed depth resolved elasticity measurement based on a quantitative optical coherence elastography system with integrated Fabry-Perot force sensor. stiffness muti-layer phantom under different axial force.
We develop a spatial coordinate corrected (SCC) motion tracking method for optical coherence elastography. SCC refers the instantaneous velocity field extracted from tomography (OCT) data to laboratory system and accurately reconstructs displacement established during mechanical excitation (compression) process. acquired image compression OCE experiments on human breast tissue specimens, reconstructed through Doppler analysis of OCT data. Our results suggested that enables accurate...
