A medical imaging and therapy device is provided that may include any of a number of features. One feature of the device is that it can acoustically couple an ultrasound therapy transducer to a patient. In some embodiments, the medical imaging and therapy device is configured to conform to the anatomy of a patient's perineal area to acoustically couple an ultrasound therapy transducer to the patient for treatment of BPH. The medical imaging and therapy device can be used in therapeutic applications such as Histotripsy, Lithotripsy, and HIFU, for example. Methods associated with use of the medical imaging and therapy device are also covered.

Disposable acoustic coupling medium container

A head holder made of radiolucent material is attached near an end of a table to support a head of a patient during a CT scan. The head holder includes a base portion that supports the shoulders and upper back of the patient and a head rest that supports a patient's head. The head holder is moveable relative to the table in a direction that is generally parallel to a length of the table. A position of the head rest is adjustable in a vertical direction relative to the base portion. The radiolucent material of the head holder does not affect the quality of a resulting CT scan.

Adjustable head holder for use with CT scanner

A CT scanner includes a pair of shields to protect an operator from x-rays from the CT scanner. The CT scanner has a gantry that provides structural support and housing for the components including an x-ray source and a detector arranged on the gantry to face one another. Lead shields are located on opposing sides of the x-ray source and extend between the x-ray source and the detector. The CT scanner further includes a computer located on an opposing side of the gantry from the x-ray source and the detector. The lead shields rotate with the gantry and prevent the x-ray from reaching the operator while the CT scanner is in operation.

Self-shielded CT scanner

A surgical navigation system includes a CT scanner that takes a plurality of x-ray images of a patient. A patient tracker including locators is attached to the patient, and a registration appendage is removably secured to the patient tracker in a known position and orientation. The registration appendage includes radio-opaque markers arranged in a predetermined geometric pattern. The registration appendage is viewable in a CT scan in situations where the locators of the patient tracker are outside of a field of view of the CT scanner.

A CT scanner includes a base, two fixed portions extending transversely from the base, and a rocking beam pivotally attached to the base about an axis. The CT scanner includes four wheels that allow the CT scanner to move over a floor. A wheel is attached to each fixed portion, and a wheel is attached to each end of the rocking beam. If the CT scanner is positioned on a floor with an unlevel portion, the rocking beam rotates about the axis. One wheel attached to the rocking beam raises in a generally vertical direction, and the other beam attached to the rocking beam lowers in a generally vertical direction so all four wheels contact the floor, stabilizing the CT scanner and preventing rocking.

CT scanner with tripod base

A CT scanning system provides the ability to scan a patient's lower extremities while the patent is upright, i.e. either standing on the foot, or at least putting some load on the foot, or with the ankle at a given angle. The CT scanning system provides a generally horizontal upper support surface on which the patient's foot is supported. A gantry supporting an x-ray source and x-ray detector are rotated about a z-axis through the support surface. With the CT scanning system, the patient's lower extremities can be scanned while under load.
