Interactive Echocardiography Translation Using Few-Shot GAN Transfer Learning.
Interactive Echocardiography Translation Using Few-Shot GAN Transfer Learning. Comput Math Methods Med. 2020;2020:1487035 Authors: Teng L, Fu Z, Ma Q, Yao Y, Zhang B, Zhu K, Li P Abstract Background: Interactive echocardiography translation is an efficient educational function to master cardiac anatomy. It strengthens the student's understanding by pixel-level translation between echocardiography and theoretically sketch images. Previous research studies split it into two aspects of image segmentation and synthesis. This split makes it hard to achieve pixel-level corresponding translation. Besides, it is also challenging to leverage deep-learning-based methods in each phase where a handful of annotations are available. Methods: To address interactive translation with limited annotations, we present a two-step transfer learning approach. Firstly, we train two independent parent networks, the ultrasound to sketch (U2S) parent network and the sketch to ultrasound (S2U) parent network. U2S translation is similar to a segmentation task with sector boundary inference. Therefore, the U2S parent network is trained with the U-Net network on the public segmentation dataset of VOC2012. S2U aims at recovering ultrasound texture. So, the S2U parent network is decoder networks that generate ultrasound data from random input. After pretraining the parent networks, an encoder network is attached to the S2U parent network to translate ultrasound images into sketch ima...

CONCLUSION: In this study, we found a strong correlation between ScvO2 and NIRS measurements taken from the internal jugular vein site. Accordingly, continuous noninvasive monitoring with transcutaneous NIRSijv can be an alternative method as a trend monitor for the central venous oxygen saturation in pediatric cardiac patients undergoing congenital cardiac surgery.

AbstractPurposeRobot-assisted laparoscopic radical prostatectomy (RALRP) using the da Vinci surgical robot is a common treatment for organ-confined prostate cancer. Augmented reality (AR) can help during RALRP by showing the surgeon the location of anatomical structures and tumors from preoperative imaging. Previously, we proposed hand-eye and camera intrinsic matrix estimation procedures that can be carried out with conventional instruments within the patient during surgery, take
Authors: Piłat P, Borzęcki A, Jazienicki M, Gerkowicz A, Szubstarski F, Krasowska D Abstract Introduction: There are many papers in the available literature on the pre-operative evaluation of malignant melanoma (MM) using a 20 MHz probe. In many Western European countries, this examination is standard in the diagnosis of such lesions in terms of the resection margin. However, few papers describe and compare the results of melanoma thickness measurements using 20 and 50 MHz frequency probes. Aim: The aim of the study was to evaluate the thickness of melanoma using 20 and 50 MHz probes. In addition, the obtaine...
CONCLUSIONS: As the tibial nerve and its branches presents a huge variability in the medial ankle area in order to prevent the iatrogenic injuries the preoperative or intraoperative ultrasound assessment (sonosurgery) of its localization should be introduced into the clinic.

Authors: Parker KJ, Poul SS Abstract After 100 years of theoretical treatment of speckle patterns from coherent illumination, there remain some open questions about the nature of ultrasound speckle from soft vascularized tissues. A recent hypothesis is that the fractal branching vasculature is responsible for the dominant echo pattern from organs such as the liver. In that case, an analysis of cylindrical scattering structures arranged across a power law distribution of sizes is warranted. Using a simple model of echo strength and basic transformation rules from probability, we derive the first order statist...
