Simplify Medical closes $23m in 2nd tranche of Series B
Simplify Medical said today it closed $23.3 million as part of the second tranche of its oversubscribed Series B financing, which brought in a total of $44.3 million for the company and its namesake cervical disc replacement. The Sunnyvale, Calif.-based company’s Simplify disc is designed to be magnetic resonance imaging safe and to eliminate imaging artifacts created by metals through the use of a PEEK-on-ceramic construction. The Simplify disc won CE Mark approval in the European Union in February 2015. “Having an oversubscribed Series B is a testament to the large opportunity presented by the Simplify Dis...

Framework of Computer Aided Diagnosis Systems for Cancer Classification Based on Medical Images
AbstractEarly detection of cancer can increase patients ’ survivability and treatment options. Medical images such as Mammogram, Ultrasound, Magnetic Resonance Imaging, and microscopic images are the common method for cancer diagnosis. Recently, computer-aided diagnosis (CAD) systems have been used to help physicians in cancer diagnosis so that the dia gnosis accuracy can be improved. CAD can help in decreasing missed cancer lesions due to physician fatigue, reducing the burden of workload and data overloading, and decreasing variability of inter- and intra-readers of images. In this research, a framework of CAD systems ...

Development of a Searchable System to Confirm MR Imaging Safety Information for Implantable Medical Devices.
Abstract The purpose of this study was to develop a searchable system to confirm magnetic resonance (MR) safety information of implantable medical devices (IMDs) to safely perform magnetic resonance imaging examinations. We labeled MR safety information for IMDs based on package insert descriptions and then categorized allowed MR conditions for IMDs. Finally, a searchable system was developed to use the database via the internet. This system enables efficient and accurate confirmation of MR safety information for IMDs.

Multi-Modal Deep Guided Filtering for Comprehensible Medical Image Processing
Deep learning-based image processing is capable of creating highly appealing results. However, it is still widely considered as a “blackbox” transformation. In medical imaging, this lack of comprehensibility of the results is a sensitive issue. The integration of known operators into the deep learning environment has proven to be advantageous for the comprehensibility and reliability of the computations. Consequently, we propose the use of the locally linear guided filter in combination with a learned guidance map for general purpose medical image processing. The output images are only processed by the guided...

Three-Dimensional Printing in Medical and Allied Health Practice: A Literature Review
Three-dimensional printing (3DP), first implemented as nonmedical science in engineering in 1986, has grown immensely in its current integration into the health care field. Three-dimensional printing may possibly lower health care costs and promote a higher quality of patient care. The implementation of 3DP in conjunction with postprocessing computed tomography and magnetic resonance imaging has opened up avenues for the medical and allied health fields including prosthetics, surgery, radiation therapy, medical dosimetry, biomedical research, and organ transplantation.

A review of deep learning based methods for medical image multi-organ segmentation
Medical image segmentation is one of the most important medical image analysis tasks. It has a wide range of applications in imaging systems such as microscopy, X-ray, ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET). Medical image segmentation plays an essential role in radiotherapy, which is the standard care for certain cancers [1]. The success of radiotherapy depends highly on accurate irradiation to the target and sparing of organs-at-risk (OARs) [2,3].

Consensus statement for the management of incidentally found brain white matter hyperintensities in general medical practice
Med J Aust. 2023 Aug 21. doi: 10.5694/mja2.52079. Online ahead of print.ABSTRACTINTRODUCTION: There is a paradigm shift in our understanding of white matter hyperintensities (WMH) found on brain imaging. They were once thought to be a normal phenomenon of ageing and, therefore, warranted no further investigation. However, evidence now suggests these lesions are markers of poor brain and cardiovascular health, portending an increased risk of stroke, cognitive decline, depression and death. Nevertheless, no specific guidelines exist for the management of incidentally found WMH for general medical practitioners and other clin...

The Guardian view on vital medical research on primates: don’t give in to the animal rights advocates
Some medical research on primates is vital. It must be humanely conducted, but abandoning it would be craven and foolishThe extraordinary triumph of the neuroscientists in California who have wired up a paralysed man’s brain so that his impulses to move can control a robot arm deserves a toast – and not just the drink that Erik Sorto can now raise unaided to his lips for the first time in 13 years. It also shows the importance of research on higher primates. Without detailed preliminary studies on monkeys, whose brains in important respects resemble our own, this kind of transformative treatment could never have b...

In Vivo Cellular Imaging for Translational Medical Research.
Authors: Arbab AS, Janic B, Haller J, Pawelczyk E, Liu W, Frank JA Abstract Personalized treatment using stem, modified or genetically engineered, cells is becoming a reality in the field of medicine, in which allogenic or autologous cells can be used for treatment and possibly for early diagnosis of diseases. Hematopoietic, stromal and organ specific stem cells are under evaluation for cell-based therapies for cardiac, neurological, autoimmune and other disorders. Cytotoxic or genetically altered T-cells are under clinical trial for the treatment of hematopoietic or other malignant diseases. Before using stem cell...

Four Challenges in Medical Image Analysis from an Industrial Perspective
Over the last 20 years, medical imaging systems have evolved considerably. Advances in acquisition technology such as multi-slice Computed Tomography (CT), digital Photon Emission Tomography (PET), parallel Magnetic Resonance Imaging (MRI) or Ultrasound (US) transducer technology have not only enabled the acquisition of much better images with higher resolution, they enabled also the generation of many more images. In addition, the diversity of imaging protocols in usage has increased. 2D imaging techniques such as 2D US and 2D X-ray remain important and are complemented by (rather than replaced by) 3D techniques.

Utility of Medical Imaging Displaying Method in 3D Magnetic Resonance Imaging.
Abstract The recent improvements in magnetic resonance (MR) hardware, especially 3T devices, scanning protocols, and three dimensional (3D) volumetric reconstruction software have facilitated great expansion of the role of 3D imaging. With the volumetric data, various post processing image reconstructions could readily be done on the 3D workstation. The reconstructions allow better demonstration of anatomic details, which help improve lesion localization and surgical planning. Particularly, in patients who are planned for surgery such as tumors assessment or pre-transplant evaluation, the 3D reconstructions provid...
