Matthew Toews, William M Wells
This paper presents a method for automatically calibrating and assessing the calibration quality of an externally tracked 2D ultrasound (US) probe by scanning arbitrary, natural tissues, as opposed a specialized calibration phantom as is the typical practice. A generative topic model quantifies the posterior probability of calibration parameters conditioned on local 2D image features arising from a generic underlying substrate. Autocalibration is achieved by identifying the maximum a-posteriori (MAP) image-to-probe transform, and calibration quality is assessed online in terms of the posterior probability of the current image-to-probe transform...

Gallbladder (GB) adenomyomatosis (ADM) is a benign, acquired anomaly, characterized by hypertrophy of the mucosal epithelium that invaginates into the interstices of a thickened muscularis forming so-called Rokitansky-Aschoff sinuses. There are three forms of ADM: segmental, fundal and more rarely, diffuse. Etiology and pathogenesis are not well understood but chronic inflammation of the GB is a necessary precursor. Prevalence of ADM in cholecystectomy specimens is estimated between 1% and 9% with a balanced sex ratio; the incidence increases after the age of 50...

BACKGROUND: Despite advances in non-invasive radiological techniques for the treatment of intussusception, management of the entity still remains exclusively surgical in many developing countries, including Ethiopia. Fluoroscopic units are rare or mostly dysfunctional. Ultrasound scanners are more commonly available. Ultrasound-guided hydrostatic reduction (USGHR) was recently introduced to the main referral hospital in Ethiopia, and subsequently has been adopted as the initial management option for intussusception...

Talimogene laherparepvec is a herpes simplex virus-1-based intralesional oncolytic immunotherapy and is the first oncolytic virus to be approved in Europe. It is indicated for the treatment of adults with unresectable melanoma that is regionally or distantly metastatic (stage IIIB, IIIC, and IVM1a) with no bone, brain, lung, or other visceral disease. Talimogene laherparepvec is a genetically modified viral therapy, and its handling needs special attention due to its deep freeze, cold-chain requirements, its potential for viral shedding, and its administration by direct intralesional injection...

Giant nonparasitic splenic epidermoid cysts are relatively uncommon. These lesions can lead abdominal pain, but most of then are asymptomatic, and they are discovered incidentally. We report a 13-y old female with a giant splenic epidermoid cystic, given the special interest of diagnostic and therapeutic decision-making of this rare entity. CASE REPORT: A 13-y old female with clinical history of abdominal pain since the last two months. On physical examination a firm, tender mass was palpable in left hypochondrium...

A new continuous-flow ultrasound assisted oxidative desulfurization (UAOD) process was developed in order to decrease energy and aqueous phase consumption. In this process the aqueous phase is injected below the horn tip leading to enhanced mixing of the phases. Diesel fuel as the oil phase with sulfur content of 1550ppmw and an appropriate mixture of hydrogen peroxide and formic acid as the aqueous phase were used. At the first step, the optimized condition for the sulfur removal has been obtained in the batch mode operation...

Perinatal autopsy remains the gold-standard procedure used to establish the fetal, neonatal or infant abnormalities. Progressively, perinatal pathology has become a specialized field with important roles of audit for fetal prenatal diagnostic tools, in parents counseling regarding future pregnancies, in scientific research, for epidemiology of congenital abnormalities and teaching. The differences between prenatal ultrasound and autopsy reports represent a strong argument for the autopsy examination following termination of pregnancy...

Conventional two-dimensional (2D) ultrasound imaging is a powerful diagnostic tool in the hands of an experienced user, yet 2D ultrasound remains clinically underutilized and inherently incomplete, with output being very operator dependent. Volumetric ultrasound systems can more fully capture a three-dimensional (3D) region of interest, but current 3D systems require specialized transducers, are prohibitively expensive for many clinical departments, and do not register image orientation with respect to the patient; these systems are designed to provide improved workflow rather than operator independence...

Background: Liver resection (LR) is the treatment of choice for most benign and malignant focal liver lesions, as well as in selected patients with liver trauma. Few other therapies can compete with LR in selected cases, such as liver transplantation in hepatocellular carcinoma (HCC) and ablative therapies in small HCCs or liver metastases. The present paper analyses a single center experience in LR, reviewing the indications of LR, the operative techniques and their short-term results. MATERIAL AND METHOD: Between January 2000 and December 2016, in "œDan Setlacec" Center of General Surgery and Liver Transplantation were performed 3165 LRs in 3016 patients, for pathologic conditions of the liver...

REVIEW
Jeroen J Kolkman, Robert H Geelkerken
Although the prevalence of mesenteric artery stenoses (MAS) is high, symptomatic chronic mesenteric ischemia (CMI) is rare. The collateral network in the mesenteric circulation, a remnant of the extensive embryonal vascular network, serves to prevent most cases of ischemia. This explains the high incidence of MAS and relative rarity of cases of CMI. The number of affected vessels is the major determinant in CMI development. Most subjects with single vessel mesenteric stenosis do not develop ischemic complaints...

The purpose of this work was to develop a multichannel ultrasonic measurement method for monitoring a spatially non-uniform blood clotting process. This novel method is based on simultaneous multi-channel measurements of ultrasound propagation velocities in different horizontal cross-sections of clotting blood. The most common method used for determining blood-clotting time is the capillary tube method. For this purpose ultrasonic methods based on measurements of the velocities of ultrasound waves in clotting blood are also used...

Nowadays noninvasive vascular imaging has an important role in the diagnostic work-up of the large vessel vasculitides (LVV), most importantly giant cell arteritis (GCA) and Takayasu arteritis. Among the imaging modalities available, ultrasound (US) has several important advantages, including low costs, rapid and repetitive availability without exposure to radiation, and high spatial resolution for assessment of large and medium-sized arteries. Therefore, US can be regarded the first line imaging method in suspected LVV...
