Abstract: A multi-frequency ultrasound therapy apparatus is configured to operate at its center frequency and at the higher harmonic of its center frequency. The center frequency can be for the entire apparatus or for each ultrasound source element. At least one source element can generate ultrasound energy at its center frequency while, simultaneously, at least another source element can generate ultrasound energy at the higher harmonic of its center frequency. In addition, the same source element can generate ultrasound energy at its center frequency and the higher harmonic of its center frequency, respectively, but at different times. A data storage unit that stores encrypted and encoded data is disposed on the apparatus. The encoded data includes a unique identification code of the apparatus, the condition of use of the apparatus, the center frequency of each source element, the ultrasound efficiency of each source element, and/or other parameters relating to the apparatus.

Abstract: An apparatus and method for medical imaging uses a first and second contrast agent, the second agent targeted to a particular tissue type. First images are obtained using the first agent, and second images using the second agent using medical imaging systems. An image processing system is adapted to process the first and second medical images by fitting parameters of a pharmacokinetic model to the first medical images, identifying a nontargeted tissue type, scaling the fitted parameters to best match the nontargeted tissue in the second medical images, executing the pharmacokinetic model to prepare a correction image, and generating corrected medical images by subtracting the correction image from the second medical images.

Abstract: A computer-implemented method of performing deep learning based isocenter positioning includes acquiring a plurality of slabs covering an anatomical area of interest that comprises a patient's heart. For each slab, one or more deep learning models are used to determine a likelihood score for the slab indicating a probability that the slab includes at least a portion of the patient's heart. A center position of the patient's heart may then be determined based on the likelihood scores determined for the plurality of slabs.

Abstract: Systems and methods for tomosynthesis with an x-ray filter are disclosed. The present technology provides performing breast tomosynthesis in the presence of an x-ray filter. For example, an x-ray filter may be placed between an x-ray source and breast tissue. The filter may proportionally filter out a subset of the energies emitted by the x-ray source. A filter may include characteristics to filter x-ray energies based on a k-edge of a contrast agent introduced into the breast, such that the breast tissue has relatively greater exposure to x-ray energies above the k-edge of the contrast agent to illuminate the contrast agent without substantial illumination of other breast tissue. Thus, tomosynthesis images similar to those obtained using subtraction may be acquired without software-based contrast enhancing techniques.

Abstract: A three-dimensional model for a patient fixation device that serves to immobilize at least a portion of a particular patient when capturing CT image information of that patient is accessed and then registered with the pixels that correspond to the patient fixation device in the CT image. The model can specify rules of movement for each of a plurality of structural elements that comprise the patient fixation device and that are capable of movement relative to one another.

Abstract: A position sensor used in medical devices for use with medical positioning systems. The position sensor includes a core (80) having a body and one or more projections (841,842) extending from the body, wherein the core comprises a high-permeability material. The position sensor further includes a coil (74) surrounding the body, wherein the coil is configured to generate a voltage when subject to a magnetic field. The one or more projections extending from the body of the core are configured to concentrate the magnetic field into the coil and increase the voltage. Thus, various core designs are described which have projections which may increase the electrical and/or mechanical integrity of the position sensor and/or which may also induce magnetic flux flow within the position sensor thereby increasing the signals generated by the position sensor.

Abstract: The invention relates to a method for positioning an articulated arm of a medical robot assisted by a navigation system comprising an electromagnetic field generator and two sensors. The generated field forms a measurement zone in which the position of a sensor can be determined by the navigation system and communicated to the robot. A first sensor is positioned at an anatomical location of interest of a patient. A second sensor is positioned on the articulated arm. When the two sensors are located in the measurement zone, a so-called “region of reduced influence” of the measurement zone is determined, in which the introduction of a metal object has virtually no influence on the determination of the position of the sensors by the navigation system. The articulated arm is then configured so that any metal part of the articulated arm located in the measurement zone is situated within the region of reduced influence.
