The present invention provides a device for treating dementia, including: a plurality of ultrasound probes; an ultrasound transducer arranged in each of the ultrasound probes and configured to propagate unfocused ultrasound energy to a brain; and an ultrasound generator connected to each of the ultrasound probes.

Device for treating dementia, method for operating said device, and program

A probe () transmits and receives diagnostic ultrasound and therapeutic ultrasound. A transmission unit () forms a transmission beam of the therapeutic ultrasound having a higher wave number than the diagnostic ultrasound and scans the transmission beam of the therapeutic ultrasound in a therapeutic region set inside a diagnostic region by controlling the probe (). Since the therapeutic ultrasound having a higher wave number than the diagnostic ultrasound is used, the therapeutic effect is higher than when using a therapeutic ultrasound having a similar wave number to the diagnostic ultrasound, and since the transmission beam of the therapeutic ultrasound is scanned in the therapeutic region, the therapeutic effect is higher than when the transmission beam of the therapeutic ultrasound is not scanned.

Ultrasonic treatment device

When a user designates a treatment range on a diagnostic image, a switch () selects a transmitter for treatment (). Ultrasound with intensity for treatment is thereby transmitted from a probe () to the inside of an organism. When the treatment operation continues for a prescribed time, a control unit () controls the switch () to select a transmitter for diagnosis (). The probe () thereby emits an ultrasound beam for diagnosis, senses an echo thereof, generates a diagnostic image, and carries out an inspection of a positional shift of the site to be treated. In the inspection, the control unit () compares the diagnostic image with a reference image, and if a significant difference is detected therebetween, determines that a shift has occurred, issues an alarm, and urges the user to correct the positional shift. It is possible to resume the treatment when the positional shift has been corrected.

Ultrasound diagnostic apparatus

Data communication is achieved between different LAN segments without passing the data through a router. A cell segmentation selector selects either LAN emulation or native-mode ATM for a packet made at an upper level protocol higher than a network layer. A LAN emulator makes an ATM cell from the MAC frame after the packet is made with a MAC frame. The native-mode ATM unit directly makes the ATM cell from the packet. Either the LAN emulation or the native-mode ATM is selected for operation by the cell segmentation selector. Then, the ATM cell is made by the LAN emulator or the native-mode ATM unit with reference to the selection and then the data communication is carried out using the produced ATM cell.
