ABSTRACT Purpose To develop a free‐breathing method for multi‐slice co‐registered cardiac T1, T2, and ADC maps using single‐shot spin‐echo echo planar imaging (SE‐EPI). Methods T1, T2, and diffusion weighted images in five slices were acquired with SE‐EPI readouts during free breathing using interleaved acquisition of slices, non‐selective inversion ...

ABSTRACT Background A detailed evaluation of hemodynamics, supportive morphology, and deformation may help uncover the pathophysiology of hypertrophic obstructive cardiomyopathy (HOCM) and the changes wrought by alcohol septal ablation (ASA). Purpose To investigate the global cardiac volume, myocardial deformation, and hemodynamic characteristics ...

ABSTRACT Purpose To implement and evaluate the feasibility of a Pilot Tone (PT)‐based prospective gating and tracking technique, which uses a long short‐term memory (LSTM) neural network to predict respiratory motion from PT signals. Methods A subject‐specific calibration scan consisting of 100 ECG‐triggered single‐shot images was performed ...

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

A Portable ULF scanner (1a) imaged a subject (1b) and phantom (1c) to give T2 (2a) and DW (2b) acquisitions alongside a regularised phantom fieldmap (2c). These were processed to give corrected DTI (3a) and CSD (3b) derivatives and were used for whole‐brain tractography (3c) in a feasible acquisition duration.

Abstract Maternal mortality remains a critical global public health issue, particularly in low‐ and middle‐income settings where failures in surveillance, early diagnosis, and clinical decision making compromise obstetric care. In this context, the present study aimed to critically review the scientific literature on the use of artificial intelligence (
