Company’s scanner to two clinics during the three months ended September 30, 2024 and six clinics during the nine months ended September 30, 2024.

Certain components and services used to manufacture and develop the Company’s products are presently available from only one or a limited number of suppliers or vendors. The Company’s QT Breast Scanner has more than six hundred components, of which less than five components have such dependencies on limited suppliers or vendors. The loss of any of these suppliers or vendors would potentially require a significant level of hardware and/or software development efforts to incorporate the products or services into the Company’s product.

#### Cash and Cash Equivalents
The Company considers all short-term investments with a maturity of three months or less when purchased to be cash equivalents. The Company had restricted cash equivalents of $20,000 as of September 30, 2024 and December 31, 2023.

#### Restricted Cash
Restricted cash is comprised of cash held in an account subject to a collateral agreement to be used for the Company’s corporate credit card program.

#### Accounts Receivable, Net
Accounts receivable are carried at the amount due. Accounts receivable are written off when management deems all realistic efforts to collect the amount outstanding have been exhausted. A provision for credit losses is estimated by management based on evaluations of its historical bad debt and current collection experience. As of September 30, 2024 and December 31, 2023, an allowance for credit losses was not required. Write-offs of accounts receivable were not significant during the three and nine months ended September 30, 2024 and 2023.

#### Inventory
Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average cost method. The Company periodically reviews the value of items in inventory and provides write-offs of inventory that is obsolete. Appropriate consideration is given to obsolescence, excessive levels, deterioration, and other factors in evaluating net realizable value. Once inventory has been written down below cost, it is not subsequently written up.

#### Property and Equipment, Net
Property and equipment, net are recorded at cost, less accumulated depreciation. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance, and repairs are charged to current operations as incurred. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations
