Abstract: A magnetic resonance antenna includes a surface coil and a receive coil. The magnetic resonance antenna includes one or more antenna elements. The magnetic resonance antenna further includes a preamplifier for the antenna element and a coil former for supporting the antenna element. The coil former is formed from a porous material. The antenna is divided into an irradiation zone and at least one reduced radiation zone. The preamplifier for each of multiple antenna elements is located within the at least one reduced radiation zone. The multiple antenna elements are located at least partially within the irradiation zone. The coil former has a perimeter. The irradiation zone extends continuously from a first edge of the perimeter to a second edge of the perimeter. The first edge and the second edge are opposing edges.

Abstract: The present disclosure relates to a therapy system (100) comprising a radiotherapy device (102) configured to deliver and direct a radiotherapy beam along an axis to a predefined target position (117) in an imagine zone (138, 146) within an MR module (106) of the therapy system (100). The predefined target position (117) is matched with a position of an RF coil (140) of the MR module (106).

Abstract: The invention provides for magnetic resonance antenna (100), wherein the magnetic resonance antenna is a surface coil and is a receive coil. The magnetic resonance antenna comprises one or more antenna elements (104, 404). The magnetic resonance antenna further comprises a preamplifier (402) for the antenna element and a coil former (106) for supporting the antenna element. The coil former is formed from a porous material. The antenna is divided into an irradiation zone (204) and at least one reduced radiation zone (202, 206). The preamplifier for each of multiple antenna elements is located within the at least one reduced radiation zone. The multiple antenna elements are located at least partially within the irradiation zone. The coil former has a perimeter, wherein the irradiation zone extends continuously from a first edge (208) of the perimeter to a second edge (210) of the perimeter. The first edge and the second edge are opposing edges.

Abstract: The invention provides for a medical instrument (200, 300, 400, 500, 502, 600, 700, 702, 800, 802) comprising a LINAC guided by a magnetic resonance imaging system (204). Execution of the instructions by processor to controlling the medical instrument cause the processor to: receive (100) a treatment plan (260) for irradiating the target zone; modify (102) the treatment plan in accordance with an X-ray transmission model of an accessory; acquire (104) magnetic resonance data using the magnetic resonance imaging system; reconstruct (106) a magnetic resonance image (268) from the magnetic resonance data; register (108) a location (272) of the target zone in the magnetic resonance image; generate (110) control signals (274) in accordance with the location of the target zone and the X-ray transmission model; and control (112) the LINAC to irradiate the target zone using the control signals.

Abstract: An ultrasonic treatment apparatus comprised of: a patient support for supporting a patient, an ultrasound transducer system for ultrasonic treatment of the patient, a region formed in the patient support operable for transmitting ultrasound from the ultrasound transducer system to a treatment zone in the patient, a protective cover for covering the region, and wherein the protective cover is adapted to be removed from the region while the patient is positioned relative to the treatment zone such that the treatment zone is able to receive treatment from the ultrasound transducer system.

Abstract: The invention relates to a therapeutic system which comprises: an ultrasound therapy unit (1) arranged to insonify at least a portion of a body (2) of a patient with high intensity ultrasound, wherein the ultrasound therapy unit (1) comprises an ultrasound applicator (10) attached to a patient table (9) carrying the body (2) of the patient, and a MR imaging unit (3) arranged to acquire MR signals from the portion of the body (2) and to reconstruct a MR image from the MR signals, wherein the MR imaging unit (3) comprises a RF receiving antenna (14) for receiving the MR signals. It is an object of the invention to provide a therapeutic system which facilitates a good image quality close to the ultrasound applicator and improves the usability of the therapeutic system. To this end, the invention proposes that the RF receiving antenna (14) is integrally incorporated into the patient table (9).
