Systems and methods are provided for managing and reducing the severity or impact of a collision involving an apparatus secured to a table associated with a medical imaging and / or therapeutic gantry. Example systems are provided in which an apparatus is secured to the table such that a distal region of the apparatus extends beyond a longitudinal end of the table. A pivot joint associated with the apparatus is provided such that when a collision between the distal region of the apparatus and an object occurs due to motion of the table, the resulting force causes the apparatus to rotate relative to the pivot joint, thus passively accommodating the applied force and preventing, or reducing the likelihood of, mechanical buckling of the apparatus in the presence of the force. In some example embodiments, the apparatus is configured to rotate and / or translate as a result of the force applied during the collision.

The present embodiments relate generally to enabling an end user - e.g. medical physicists - to monitor radiation therapy and, with integration to the LINAC, adaptive radiotherapy. Embodiments record signals already released during radiotherapy, requiring no new irradiation of the patient for in vivo, in line, dose monitoring. Furthermore, as the transducers will be coupled to the patient with ultrasound gel, the present embodiments are not invasive to patients and will not introduce new discomfort during therapeutic procedures. The addition of the RiAD system provides the end user with additional information during the treatment of the patient, allowing for real-time beam tracking and dosimetry, enabling the end user to practice adaptive radiotherapy. The RiAD system enables the end user to ensure that proper dose delivery is occurring with each new beamlet and dose deposition, empowering them to adapt the medical treatment as it is performed and increase its precision in conventional electron beam radiotherapy, electron FLASH radiotherapy, and intraoperative electron beam radiotherapy.

The invention discloses an execution mechanism, system and control method of a natural orifice passing diagnosis and treatment robot.

The application provides a magnetic response composite hydrogel for integrated repair of bone defects and a preparation method thereof, and belongs to the technical field of medical materials. The composite hydrogel can efficiently inhibit tumor cell activity under the time sequence regulation of an external alternating magnetic field, and then provide a suitable microenvironment and key components for bone tissue regeneration, so that signal conversion and function connection from tumor killing to bone repair are realized. The material has good injectability and self-healing ability, can minimally invasively fill irregular defects, and has significant advantages in simplifying the clinical treatment procedure, shortening the treatment course, reducing the risk of tumor recurrence and improving the repair quality, and provides a new and integrated treatment strategy for tumor-related bone defects.

Systems and methods for performing minimally invasive surgical procedures, especially for removal of tumors, and especially for brain tumors, using a robotically inserted therapeutic probe, which first detects tumorous tissue on a pre-planned path through the patient's tissue, before performing therapeutic procedures on the tissue, such as ablation. This pre-treatment detection procedure is thus able to avoid the destruction of healthy tissue. This also ensures that the therapeutic process indicated in a preoperative surgical plan is only performed on tumorous tissue, without sole reliance on preoperative image indications. This is important for neurosurgical operations performed on the brain, since preoperative images may not be accurate due to brain shift occurring during the procedure. Detection can be performed optically or ultrasonically, and treatment by laser or RF ablation. The probe insertion can be performed at 90° to the insertion axis of the device, thus minimizing passage through healthy tissue.

A diagnostic mode will guide the operator to optimize ablation parameters. This virtual pre ablation, the parenchymal ultrasound barrier and the diagnostic catheter operation should enable the operator to conduct the therapeutic procedure safe, fast and effective.

Various example embodiments of the present disclosure provide systems and methods for the dynamic correction and reduction of thermal variations in skull-induced aberrations during a focused ultrasound therapy procedure. Unlike conventional approaches involving static corrections for skull-induced aberrations, various example embodiments of the present disclosure employ ultrasound detection and a skull thickness estimate from volumetric image data to intermittently and dynamically determine corrections for skull-induced aberrations, such that aberration correction reduction is updated intraoperatively and maintained despite local thermally-induced changes in the speed of sound of the local skull region due to intraoperative intracranial heating. Furthermore, in some example embodiments, a measure dependent on the speed of sound with the skull is intraoperatively determined and compared to a previously determined value of the measure to determine a change in the skull temperature, based on a pre-determined relationship between changes in the measure and changes in skull temperature.
