Apparatus for digital imaging in the head region of a patient
An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. A control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means Collision detection means provided in the source and sensor detect a possible collision of the source and/or sensor with the patient during the motion of the source and/or sensor and the control unit responds to such detected possible collision.
X-ray emitter
An x-ray emitter includes an x-ray tube and an x-ray emitter housing. In an embodiment, the x-ray tube includes an evacuated x-ray tube housing, a cathode for emitting electrons and an anode for generating x-rays as a function of the electrons. Further, in an embodiment, the x-ray emitter housing includes the x-ray tube and outside of the x-ray tube, a gaseous cooling medium. In an embodiment, the x-ray emitter further includes a compressor for a forced convection of the gaseous cooling medium for cooling the x-ray tube, a pressure ratio between the intake side and pressure side of the compressor being greater than 1.3.
Deployable stabilization feet for a portable medical imaging system
A hydraulic stabilizer system for a portable medical imaging system. The system includes at least two hydraulic cylinders each having a shaft extending through a first wall of the respective cylinder, wherein each shaft is moveable relative to the respective cylinder. First and second ends of each shaft include a spring support element and a foot for contacting associated uneven floor portions. A retraction spring is located between the spring support element and an inner surface of the first wall of each cylinder. The system also includes a hydraulic circuit for supplying hydraulic fluid to the cylinders, wherein the cylinders are in fluid communication with each other. Hydraulic fluid is pumped into the cylinders to cause downward movement of the shafts until the feet contact the associated uneven floor portions such that the pressure exerted by the feet against the associated uneven floor portions is equalized.
SUB-SYSTEM X-RAY SOURCE MODULE
A modular x-ray imaging system includes an application specific module, a base unit in communication with the application specific module, and a mechanical support configured to support the x-ray application specific module. The base unit and application specific module are configured to communicate by wired and/or wireless communication.
BRAKING RESISTOR ARRANGEMENT IN A COMPUTED TOMOGRAPHY GANTRY
A gantry for a computed tomography device has a support structure, a pivot bearing, a rotating frame, a first braking resistor configured to electromotively brake a rotational movement of the rotating frame, and a heat conductor configured to dissipate heat from the first braking resistor. A heat conductor and a pressure duct wall are interconnected to form a heat-conductor-to-pressure-duct-wall connection that is detachable, form-fitting, planar, and thermally conductive. The heat is transferrable from the first braking resistor to the airflow via the heat conductor, the heat-conductor-to-pressure-duct-wall connection and the pressure duct wall.
Radiological imaging device with improved functioning
A radiological imaging device that includes a source that emits radiation that passes through at least part of a patient, the radiation defining, a central axis of propagation; and a receiving device that receives the radiation and is arranged on the opposite side of the patient with respect to the source. The receiving device includes a first detector to detect radiation when performing at least one of tomography and fluoroscopy, a second detector to detect radiation when performing at least one of radiography and tomography; and a movement apparatus arranged to displace the first and second detectors with respect to the source. The movement apparatus provides a first active configuration in which the radiation hits the first detector and a second active configuration in which the radiation hits the second detector.
C-arm with integrated CT system
A hybrid imaging system is disclosed including an arcuate arm defining a first and a second end the arcuate arm including a first detector assembly for 2D x-ray imaging of a patient and a second detector assembly for CT imaging of the patient, wherein the imaging system includes an internal drive mechanism for rotating the arcuate arm (e.g. translating the arcuate arm along an arcuate path) around the patient.
Self-shielded x-ray computed tomography system
A system for breast computed tomography includes a table supporting a patient in a prone position with an opening positioned for a breast of the patient to extend downwards therethrough, a gantry assembly positioned beneath the table with a platform driven to rotate by a motor, an x-ray source assembly coupled to the platform to rotate therewith and positioned to irradiate with an x-ray beam at least a portion of the breast, and a detector assembly coupled to the platform to rotate therewith and positioned to receive the x-ray beam from the x-ray source assembly. The system includes a shielding enclosure rigidly mounted atop the platform to rotate therewith, enclosing during rotation of the platform the detector assembly, the breast, and the x-ray beam, and having walls composed of a material and a thickness to attenuate an x-ray beam of a predetermined energy and intensity by a predetermined amount.
