A guiding system and a guiding method for ultrasound scanning operation are provided. The guiding system includes a handheld guiding device, a display device, an ultrasound scanning device, a prompting device, and a control host. When the handheld guiding device generates a first physical motion, the control host detects the first physical motion and generates navigation prompting information accordingly. The prompting device is suitable for presenting the navigation prompting information to guide the ultrasound scanning device to move to generate a second physical motion. The control host captures an ultrasound image via the ultrasound scanning device and sends the ultrasound image to the display device at a guiding end for display.

Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

Described herein are accelerator devices for providing a couplant while moving an ultrasound probe over a surface. The devices may include a reservoir configured to hold ultrasound couplant. The reservoir may attach to a probe so as to dispense the couplant at one or more locations along a perimeter of the probe while moving the ultrasound probe over the surface. The devices may additionally, or alternatively, include a membrane configured to hold ultrasound couplant. The membrane may charge a couplant layer of an ultrashield prior to or while moving the ultrasound probe over a surface during an ultrasound procedure.

A clamping device for reducing blood flow in a human limb comprises a first rigid part having a first inner profile, and a second rigid part having a second inner profile generally facing the first inner profile. A coupling portion couples the first rigid part and second rigid part to each other. The first inner profile extends further away from the coupling portion than the second inner profile. The first and second inner profiles define a recess, the recess being shaped to enable the clamping device to be positioned on the human limb, and the clamping device being configured to shift between an expanded configuration and a clamped configuration. The first and second inner profiles are arranged to apply pressure against the human limb when the device is in the clamped configuration and thereby to apply pressure to blood vessels in the human limb and reduce blood flow through the blood vessels.

A system for providing navigational guidance to a sonographer acquiring images is disclosed. The system may provide haptic feedback to the sonographer. The haptic feedback may be provided through an ultrasonic probe or a separate device. Haptic feedback may include vibrations or other sensations provided to the sonographer. The system may analyze acquired images and determine the location of acquisition and compare it to a desired image and a location for obtaining the desired image. The system may calculate the location for obtaining the desired image based, at least in part, on the acquired image. The system may then provide the haptic feedback to guide the sonographer to move the ultrasonic probe to the location to acquire the desired image.

Disclosed herein is a medical system (100, 300, 500) comprising: a memory (110) storing machine executable instructions, at least one set of predetermined coordinates (124), and a position identifying algorithm (122). The position identifying algorithm is configured for outputting a set of current coordinates (128) for each of the at least one set of predetermined coordinates in response to receiving a current image descriptive of an object (306, 310). The execution of machine executable instructions (120) causes a computational system (104) to repeatedly receive (200) a current image (126) from a camera system (304). The execution of machine executable instructions (120) causes a computational system (104) to perform the following for the current image: receive (202) the set of current coordinates for each of the at least one set of predetermined coordinates in response to inputting the current image into the position identifying algorithm; calculate (204) a positional difference (130) between the at least one set of predetermined coordinates and its set of current coordinates; calculate (206) a one-dimensional value (134) from positional difference using an objective function; and provide (208) a one-dimensional position indicator (136, 314, 600, 602, 608, 800, 900, 1002) for each of and controlled by each one-dimensional value in real time using a user interface (108, 308, 416, 418).

Disclosed are a bladder monitoring apparatus which accurately determines a bladder status of a subject based on an ultrasonic image and a posture of the subject and a method for controlling the bladder monitoring apparatus. The bladder monitoring apparatus includes a processor, a memory configured to operably connected to the processor and store at least one code executed by the processor, and a transceiver configured to receive a reflection ultrasonic signal from a subject and a posture sensing signal obtained by sensing a posture of the subject based on a sensor, and the memory may store a code which is executed by the processor to cause the processor to determine the bladder status of the subject by applying the machine learning-based learning model to an ultrasonic image generated from the reflection ultrasonic signal and posture information generated based on the posture sensing signal.

Technology is described that can be used for continuous measurements of blood pressure and arterial blood flow to automatically derive time-varying estimates of multiple factors pertaining to a patients vascular system. Such factors can include, but are not limited to, resistive flow, capacitive flow, vascular resistance, and arterial capacitance. Determination of such factors can allow for the meaningful assessment of the control of vascular resistance and capacitance in real time.

A trigger point treatment system for treating a patient, includes a cart, including a display; a trigger point scanning device with a scanning probe, and a trigger point massage therapy device, including a pressure point tip, a pressure sensor component, and an actual pressure indicator. A method of trigger point treatment includes scanning for myofascial trigger points, including locating, mapping, and marking trigger points; measuring a pressure pain threshold; applying a massage treatment; and optionally applying an injection treatment.

An ultrasonic diagnostic device providing a user preset and a method of operating same. In one embodiment, an ultrasonic diagnostic device can display change history information and use history information of at least one user preset.
