This paper provides linear analysis for a practical ultrasound imaging system with single-element transducers. A proper eighth-order linear ARMA model with inputs and outputs of voltage traces is given to present the transfer characteristics of such a practical system, so that echo signals containing tissue information can be collected and analyzed more properly.

Choledochal cyst or biliary tract cyst is a pathological condition characterized by abnormal dilation of the hepatobiliary system. In veterinary medicine, case descriptions and histological characterizations of this biliary malformation are scarce, requiring reliance on data from human medicine. A presumptive diagnosis typically involves imaging studies, with histopathological examination required for confirmation.

Metastatic lateral pelvic lymph node (LPN) in rectal cancer has a significant clinical impact on the prognosis and treatment strategies. But there are still debates regarding prediction of lateral pelvic lymph node metastasis and its oncological impact. This review explores the evidence for predicting lateral pelvic lymph node metastasis and survival in locally advanced rectal cancer.

Purpose: This study aims to analyze microvascular reconstruction in Oral and Maxillofacial Surgery (OMFS) in Europe.
Methods: Based on previous studies, a dynamic online questionnaire was developed and subjected to internal and external evaluation. The questionnaire comprised multiple-choice, rating, and open-ended questions, addressing general and specific aspects and the impacts of the COVID-19 pandemic on microvascular reconstruction in OMFS in Europe.

Background: Invasive systems are commonly used for monitoring intracranial pressure (ICP) in traumatic brain injury (TBI) and are considered the gold standard. The availability of invasive ICP monitoring is heterogeneous, and in low- and middle-income settings, these systems are not routinely employed due to high cost or limited accessibility. The aim of this consensus was to develop recommendations to guide monitoring and ICP-driven therapies in TBI using non-invasive ICP (nICP) systems.
