Augmented reality system lets doctors see under patients' skin without the scalpel

(University of Alberta) New technology is bringing the power of augmented reality into clinical practice. The system, called ProjectDR, allows medical images such as CT scans and MRI data to be displayed directly on a patient's body in a way that moves as the patient does.

Publication date: Available online 20 August 2018Source: NeurocomputingAuthor(s): Junjie Zhang, Yong Xia, Haoyue Zeng, Yanning ZhangAbstractDetection of pulmonary nodules on chest CT is an essential step in the early diagnosis of lung cancer, which is critical for best patient care. In this paper, we propose an automated pulmonary nodule detection algorithm, denoted by NODULe, which jointly uses a conventional method for nodule detection and a deep learning model for genuine nodule identification. Specifically, we first use multi-scale Laplacian of Gaussian (LoG) filters and prior shape and size constraints to detect nodul...

This study aimed to compare the clinical effectiveness of urine exfoliated cells FISH examination, CT scan, and urine cytologic examination on the diagnosis of upper urinary tract urothelium carcinoma with hematuresis symptom. MATERIAL AND METHODS A total of 30 patients with suspicious upper urinary tract urothelium carcinoma between Aug 2010 and Aug 2011 were enrolled, including 23 males and 7 females. All the subjects received urine exfoliated cells FISH examination, CT scan, and urine cytologic examination. Twenty-one cases were diagnosed as urothelium carcinoma, including 14 cases of carcinoma of renal pelvis and 7 cas...

ConclusionFor the CBCT model used in this study, optimization implies the use of the highest kV along with the shortest exposure time and a task-specific mA. The proposed step-wise optimization approach could be applied to any CBCT unit, preferably during commissioning.

Conclusion: There is a considerable variation in the position of IAN throughout its course in the mandible. Henceforth, advanced diagnostic images such as CBCT should be strongly recommended in evaluating the position of IAN preoperatively before advanced implant surgical techniques, nerve repositioning, and any other surgical procedures.

AbstractAlzheimer ’s disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. Beta-amyloid (Aβ) deposition and neurofibrillary tangles (NFTs) of abnormal hyperphosphorylated tau protein are the pathological hallmarks of the disease, accompanied by other pathological processes such as microglia activation. Functional and molecular nuclear medicine imaging with single-photon emission computed tomography (SPECT) and positron emission tomography (PET) techniques provides valuable information about the underlying pathological processes, many years before the appearance of cl ini...

Further evaluation revealed bilateral visual acuity of finger counting close to face vision with an accurate projection of rays. Computed tomography scan of the head and orbit revealed diffuse orbital hemorrhage (mainly along the ocular coats) in the absence of any subperiosteal or intracranial hemorrhage. A complete hematological workup was done and it ...
