Abstract:
A new and improved anatomical imaging system which includes a new and improved movement system, wherein the movement system comprises an omnidirectional powered drive unit and wherein themovement system can substantially eliminate lateral walk (or drift) over the complete stroke of a scan, even when the floor includes substantial irregularities, whereby to improve the accuracy of the scan results and avoid unintentional engagement of the anatomical imaging system with the bed or gurney which is supporting the patient.
Abstract:
There is disclosed a mobile radiographic imaging apparatus including a component operable to emit radiation for imaging a subject, an arm rotatably connected at a proximal end thereof to a body section of the apparatus, such that it is supported by the body section and can slew relative to the body section about an upright axis, and to a distal end of which said component is connected, and a generator assembly arranged in the body section and including a generator arranged in the casing and electrically connected to said component, the apparatus being configured such that the generator assembly rotates with the arm, about said axis, wherein the generator assembly has a centre of mass which is radially offset from said axis in a second direction that is substantially opposite to said first direction.
Abstract:
A method includes receiving a subject support motion disable signal indicative of at least one of power removal of an imaging system, a collision of a horizontally moving tabletop of the imaging system, a decoupling of a horizontal motion drive system configured to horizontally drive the tabletop, or a collision of a vertically moving subject support of the imaging system, wherein a vertical motion drive system drives the subject support vertical motion, and disabling, in response to receiving the subject support motion disable signal, at least one of tabletop horizontal motion or subject support vertical motion.
Abstract:
When performing nuclear (e.g., SPECT or PET) and CT scans on a patient, a volume cone -beam CT scan is performed using a cone-beam CT X-ray source (20) and an offset flat panel X-ray detector (22). A field of view of the X-ray source overlaps a field of view of two nuclear detector heads (18), and the offset of the X-ray detector (22) minimizes interference with nuclear detector head movement about a rotatable gantry (16). Additionally, a locking mechanism (80) provides automatically locking of the X-ray detector (22) in each of a stowed and operation position, improving safety and CT image quality.
Abstract:
Die Erfindung betrifft eine Patientenpositioniervorrichtung (1), aufweisend eine Patientenliege (2), die eine Liegefläche (2a) für eine Person aufweist, einen Roboterarm (3) mit mehreren Gliedern und mehreren Gelenken, die in einer kinematischen Kette des Roboterarms (3) seriell abwechselnd hintereinander angeordnet sind, wobei das in der kinematischen Kette des Roboterarms (3) erste Glied (4.1) ein Grundgestell zum Befestigen des Roboterarms (3) auf einer Standfläche (6) bildet, und das in der kinematischen Kette des Roboterarms (3) letzte Glied (4.8) einen Befestigungsflansch des Roboterarms (3) bildet, an dem die Patientenliege (2) befestigt ist. Die Erfindung betrifft außerdem einen medizinischen Arbeitsplatz (8), aufweisendein medizintechnisches Gerät (9) und eine solche Patientenpositioniervorrichtung (1).
Abstract:
The present invention is a rotary C-arm type of digital radiographic mechanical positional system mounted on a floor that includes a fixed vertical column with a rotational freedom, an X-ray source that provides the system with a plurality of X-rays and a locking rotary C-arm. The system also includes a single image collector disposed on the distal end of the rotary arm, a rotatable wheeled trolley that is attached to the rotary C-arm and the X-ray source and one or more safety stops. The system can also be a radiographic mechanical positional Bucky system. The present invention provides a hybrid design combining the benefits of both C-arm and Bucky systems, while providing greatly improved safety features ηοί previously available on these systems.
Abstract:
The invention relates to an adjusting member (3) for adjusting an angle of inclination between an adjustable supporting part (2) and a fixed supporting part (1) of a patient support system for e.g. radiotherapeutic purposes. The adjusting member comprises a first part and a second part in which the first part of the adjusting member is fixedly mounted on one of the supporting parts and the second part of the adjusting member is mounted movable along the other supporting part, in which the second part can be moved along said supporting part with the help of a wire (18) system and an adjusting member.
Abstract:
A digital, flat panel, two-dimensional x-ray detector (34) moves reliably, safely and conveniently to a variety of positions for different x-ray protocols for a standing, sitting or recumbent patient. The system makes it practical to use the same detector for a number or protocols that otherwise may require different equipment, and takes advantage of desirable characteristics of flat panel digital detectors while alleviating the effects of less desirable characteristics such as high cost, weight and fragility of such detectors.
