Disclosed is a system for injecting a radioactive product to a patient, wherein the system includes: a first syringe containing the radioactive product, whose plunger cooperates with an injection mass, acting by gravity, associated with deactivatable holding element; a mobile stop arranged to constitute an end-of-travel stop for the retraction of the plunger, as a function of the volume of radioactive product to be injected to the patient; a second syringe containing a rinsing product, whose plunger cooperates with a rinsing mass, acting by gravity, associated with deactivatable holding element; a trigger control element for triggering the injection of the radioactive product to the patient; and a management element including a unit for displacing the mobile stop structure as a function of the prescribed activity to be injected to the patient, and a unit for controlling the deactivatable holding element of the masses.

An engagement mechanism associated with a reciprocally movable piston of a fluid injector is configured for releasably engaging an engagement portion at a proximal end of a rolling diaphragm syringe having a flexible sidewall configured for rolling upon itself when acted upon by the piston. The engagement mechanism has a plurality of engagement elements reversibly and pivotally movable about a pivot pin relative to the engagement portion of the syringe between a first position, where the plurality of engagement elements are disengaged from the engagement portion of the syringe, and a second position, where the plurality of engagement elements are pivotally movable about the pivot pin in a radially inward direction to engage with the engagement portion of the syringe. The engagement mechanism further has a drive mechanism for moving the plurality of engagement elements between the first position and the second position.

An MRI system (100) is proposed (for generating one or more images of a body-part of a patient under analysis); the MRI system (100) comprises an injector head assembly (155), for injecting at least one medical fluid into the patient, having a clock unit (340) for providing a clock signal with a clock frequency. The MRI system (100) comprises means (420-425; 445-460) for adjusting the clock frequency in response to a manual command and/or to a detection of a degradation of the images. An injector system (155,165) for use in this MRI system (100) is also proposed. Moreover, a corresponding method (500) for managing the injector head assembly (155) is proposed. A computer program (400) for implementing the method (500) and a corresponding computer program product are also proposed.

Disclosed are an optimization method and system for a personalized contrast test based on deep learning, in which a contrast medium optimized for each individual patient is injected to implement optimum pharmacokinetic characteristics in a process of acquiring a medical image, the method including: obtaining drug information of a contrast medium and body information of a patient, in a contrast enhanced computed tomography (CT) scan; generating injection information of the drug to be injected into the patient by a predefined algorithm based on the drug information and the body information; injecting the drug into the patient based on the injection information, and acquiring a medical image by scanning the patient; and amplifying a contrast component in the medical image by inputting the medical image to a deep learning model trained in advance.

Provided herein is a system for homogeneous injection of medicine including a device for homogeneous injection of medicine, which may include a cylinder holding part having a cylinder of a syringe held therein, a plunger resting part being configured to be independent from the cylinder holding part and having an end of the plunger of the syringe rest therein, first and second pressurized lead screw supporting parts each being provided on one side of the cylinder holding part and one side of the plunger resting part, respectively, and being connected to a pressurized lead screw being provided with a screw thread, and a motor being connected to one side of the first pressurized lead screw supporting part so as to rotate the pressurized lead screw; and a monitoring unit monitoring injection dosage and having one side connected to a needle of the syringe or a medicine outlet of the syringe cylinder and having its opposite side connected to a tube providing medicine to a patient, thereby monitoring physical quantities related to the injection of the medicine.

Balloon catheters that includes inner and outer elongate shafts, each of which is secured relative to an end of an inflatable member. The inner and outer elongate shafts are secured relative to one another at one more discrete connection locations. The balloon bonding locations are disposed radially inward relative to an outer dimension of the outer elongate shaft.

A system and method for inductive heating applications includes positioning one or more inductive heating elements in a location, delivering electromagnetic radiation, by a radiation source, to heat at least a portion of the one or more inductive heating elements, and detecting, by a detector, the heat generated by the one or more inductive heating elements. The system and method also include controlling, by a processing unit, a condition based on the detected heat.

Methods and systems are provided for adaptive scan control. In one embodiment, a method includes upon a first contrast injection, processing acquired projection data of a subject to measure a contrast signal of the first contrast injection, estimating a time when a venous return to baseline (VRTB) of the first contrast injection is to occur based on the contrast signal, and commanding initiation of a second contrast injection at the estimated time.

A system and method for integrating and synchronizing an automated mechanical cardiopulmonary resuscitation (CPR) device with components of cardiac catheterization laboratories so as to enhance the efficacy of each intervention. Synchronization can include image gating so that a monitor shows real time images during relaxation of the CPR, and a static image during compression of the CPR.

A fluid delivery system is disclosed which comprises at least one supply station for supplying at least one fluid, a pressurizing unit for pressurizing said at least one fluid, an inlet fluid circuit in fluid communication with said at least one supply station and with a pump module of said pressurizing unit and an outlet fluid circuit in fluid communication with said pump module for discharging the fluid from the chamber. The chamber is provided with a piston reciprocating therein, thereby defining first and second variable-volume sub-chambers. The fluid delivery system further comprises a recirculation fluid circuit fluidically connecting said first and second variable-volume sub-chambers, and an actuator associated to said recirculation fluid circuit for managing the passage of said at least one fluid between said first and second variable-volume sub-chambers in both directions. A method of operating the fluid delivery system is also disclosed.
