Pre-operative ultrasound scanning system for patient limb extending through a reservoir

An ultrasound scanning system adapted for scanning a joint of a limb, the ultrasound scanning system comprising:

• a reservoir defining a reservoir interior and being configured to hold a fluid and receive the limb within the reservoir interior;
• and
• a transducer disposed within the reservoir interior and comprising an array of ultrasound emitters and an array of ultrasound receivers, the transducer configured to surround the joint within the reservoir interior;
• and
• wherein the reservoir comprises one or more walls extending between a proximal reservoir opening and a distal closure, wherein the reservoir enables the limb to pass through the proximal reservoir opening and to extend beyond the distal closure, and wherein the distal closure is configured to fit around the limb to create a seal between the limb and the distal closure to prevent leakage of the fluid;
• and
• wherein the reservoir is oriented vertically such that the distal closure is located at a bottom of the reservoir, the proximal reservoir opening being located above the distal closure such that the distal closure supports a weight of the fluid within the reservoir interior.
