Abstract: Automated image analysis used in vascular state modeling. Coronary vasculature in particular is modeled in some embodiments. Methods of “virtual revascularization” of a presently stenotic vasculature are described; useful, for example, as a reference in disease state determinations. Structure and uses of a model which relates records comprising acquired images or other structured data to a vascular tree representation are described.

Abstract: Provided is an inference apparatus according to the present disclosure including: a hardware processor that: acquires ultrasound image data on an ultrasound image generated based on a reflected wave of ultrasound transmitted to a subject; and inputs the ultrasound image data, as data to be inferred, to a trained model and performs inference on a nerve root in the ultrasound image based on output data outputted from the trained model.

Abstract: A medical imaging apparatus comprises processing circuitry configured to: receive three-dimensional flow data, wherein the three-dimensional flow data comprises data acquired by medical imaging of a subject; perform a first intensity projection to process first flow data corresponding to a first region in the three-dimensional flow data having a first direction of flow, thereby obtaining a first color; perform a second, independent intensity projection to process second flow data corresponding to a second region in the three-dimensional flow data having a second direction of flow which is different from the first direction of flow, thereby obtaining a second color; combine the first color and the second color to obtain a combined color; and generate volume rendering image data based on the combined color.

Abstract: In some embodiments, a blood flow sensor device such as a non-invasive cardiac arrest monitor (NICAM) that uses ultrasound to detect blood flow is used to monitor blood flow during cardiopulmonary resuscitation. One or more gating signal generation devices transmit gating signals to a blood flow monitoring computing device. The blood flow monitoring computing device uses the gating signals to determine time periods during which blood flow information generated by the blood flow sensor device is most likely to be accurate. The blood flow monitoring computing device measures blood flow during the time periods. In some embodiments, the blood flow monitoring computing device presents the measured blood flow to a user. In some embodiments, the blood flow monitoring computing device transmits a command to a chest compression device based on the measured blood flow.

Abstract: Interventional procedures on the carotid arteries are performed through a transcervical access while retrograde blood flow is established from the internal carotid artery to a venous or external location. A system for use in accessing and treating a carotid artery includes an arterial access device, a shunt fluidly connected to the arterial access device, and a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. The flow control assembly includes one or more components that interact with the blood flow through the shunt.

Abstract: An ultrasound diagnosis apparatus according to an embodiment includes processing circuitry. The processing circuitry includes: transmitter/receiver circuitry configured to transmit an ultrasound wave to the inside of an examined subject and to receive an echo signal emitted in response to the ultrasound wave; and processing circuitry configured to extract, with respect to each spatial point, information that is related to motion velocity of a target inside the examined subject and included in a signal data sequence obtained from the echo signal, to calculate periodicity information of a movement of the examined subject on the basis of the information, and to generate a spatial distribution of the periodicity information.

Abstract: Systems and methods for microvasculature imaging acquisition are disclosed. In aspects, a full frame corresponding to a field of view of an ultrasound scanner is divided into small portions, each of which is individually scanned for a desired period of time at a higher frame rate than the ultrasound scanner is capable of using to scan the full frame. These ultrasound data acquisition techniques enable super-resolution image processing or high-sensitivity microvascular-doppler image processing to be used to track low-intensity, slow-flow microvasculature of an anatomy of a subject.
