Abstract: For autonomous MR scanning for a given medical test, a simplified MR scanner may be used without or will little input or control by a technologist (e.g., by a physician, radiologist, or person trained in MR scanner operation). The MR scanner autonomously positions, scans, checks quality, analyzes, and/or outputs an answer to a diagnostic question with or without an MR image. Scan analysis, based on artificial intelligence, allows for on-going or on-the-fly alteration of the scanning configuration to acquire the data desired to answer the diagnostic question. By using a simplified MR scanner, both position of the patient relative to the MR scanner and localization of the scan by the MR scanner are jointly solved. Sensors may sense a patient in a scan position where the reduced radio frequency requirements allow for a more open bore.

Abstract: Embodiments of the present disclosure are directed to systems, devices, and methods of inducing physical effects in tissue, such as dermis, adipose, musculoskeletal, vascular, hepatic tissue, using unfocused or planar, non-cavitating acoustic shock waves. The physical effects include disruption of fibrous extracellular matrix of the targeted tissues. Embodiments of the present disclosure include applying rapid acoustic pulses (e.g., shock waves) to cause a breakdown in the fibrous extracellular matrix to reduce the appearance of cellulite or scars in a treatment area. Such unfocused or planar, non-cavitating acoustic shock waves may induce a tissue reaction, such as reduction of fibrosis, induction of angiogenesis, or lymphangiogenesis.

Abstract: The present invention relates to a system and method for determining a vital sign of a subject. To improve the detection of electromagnetic radiation reflected from or transmitted through skin of a subject (110) at least two differently modulated radiation sources (112, 114) are used. For both camera and single-element sensors, this allows access (after demodulation) to different mixtures of skin and non-skin reflections/transmissions that can be de-mixed and successively allows the skin-only signal to be used for photo-plethysmography, PPG, extraction. Thus, a sensor (130) detects the reflected or transmitted electromagnetic radiation and a demodulation unit (140) and processing unit (150) enable to determine a vital sign (160) from said detection signal.
